Bought this crop top to wear in classes, running or on my bike. Chose large as I didn’t want one that felt tight - unlike Nike crop tops. Normally a medium in Nike and a 36 in bra size. Would recommend this product - would be nice to see some more colours in the future.
Very impressed with these. So comfortable and light. You don’t feel you have anything on. Also good medium support.
I bought one and then bought another.
I wore the under wear for my first 10k race last week. They were so comfortable to wear, no moving and kept the sweat at bay, I have my first 1/2 marathon on Sunday so I will definitely be wearing them again. Delivery was fast and I would use Runderwear again.
The crop top is very comfortable, but it’s the briefs that stand out from the crowd - I wore them yesterday for a 50 mile ultra with 11,000 feet of ascent which took me over 15 hours, and they were incredibly comfortable, didn’t move, seemed to wick sweat away, and no chafing! No more pulling knickers out of the “bum crack” every half mile, these covered where it mattered and didn’t budge.
Very comfortable, supportive, and washes well. All you need if you are not too well endowed. Sizing is possibly a bit on the small size - I have the medium and I'd say it's fine for a 32/34b, but might need to go up a size if you are any bigger.
Very comfortable wether you are running short or long distances I would definitely buy this product again.
This is my third running bra as I won't wear any other type or make.
This top is so comfortable, no chafing or rubbing. Felt really supportive but I am not the most well endowed lady :-). Bought in preparation for my 1st half marathon, i have no worries that it won't do the job on the day. Will be purchasing another
Great fit low impact bra and good price. Haven’t tried it running but will give it a go. Will buy a second one if ok.
Size small (size 8)
In the recent heat I’ve suffered from chafing on my back from my sports bras.
I’ve done 3 long runs now wearing this and have been delighted.
I’m a size 8. Small is perfect.
Super comfortable bra that conforms to your skin. Breathable and soft too.
Didn’t have time to trial this before my first ultra marathon. 50k later, no chaffing, so comfortable never noticed I was wearing it. I’m not exactly blessed in the chest department so not sure how supportive those more endowed would find it. Worked great for me.
Love my runderwear, am a size 12 so bought a large which fitted perfectly, no chafing or rubbing, wouldn't run in anything else!!
Very quick delivery.
Excellent product, fits well is very comfortable to wear.
I bought it to wear when walking the Yorkshire 3 Peaks Challenge for the British Heart Foundation, it does exactly what it says on the tin, I could not be happier.
Very comfortable to wear; bra great, as no seams, so prevents injuries over long distances.
It looked a little small when I took it out of the packet, but actually fits quite well. It's a great material and was very comfy.
I bought the crop trip specifically for an ultra run as my other running bras were rubbing after around 15 miles.
I ordered a medium which is a snug fit. It's not too tight for me but if you have larger boobs than a B cup then it may be a bit too tight for you as it flattens your breasts.
The crop top was fantastic during the ultra. No chafing or rubbing....in fact I forgot about it as other things were rubbing and took my attention!
I would defo recommend this as a good running top that's holds everything In place.
While I'm not wearing it myself my wife told me it's very comfortable and it's using it every day/
Lovely material, super comfy. It's not supportive enough for me to jump around in, but perfect for yoga, walking and cycling. I'll definitely buy more runderwear.
This was my first purchase of Runderwear top and brief. Already tested and love them.
I have just made an order for the same in black, I can only recommend. Comfortable, holds well.
These are the only ones I will wear for races and LSR the reason being the material is so soft and you would not know you are wearing then, they stay in place even for marathons
Another excellent Runderwear product. I love this crop top. Extremely comfortable.
Bought my first set at the National Running Show back in January and been eager to buy another set ever since. Absolutely fantastic! We all know that horrible sweaty under boob feeling - don’t get that with Runderwear crop top at all. So so pleased! Looking forward to some more chaff free running
I ordered this crop top in small and needed to return for a medium. I sent back on the Thursday and had my new top by the Saturday. Very Impressed with delivery and a great crop top which I use for running. I do not need much support but for an A cup does the job and it is so comfy and soft.
Can recommend the runderwear bra - just the right amount of tension for me 34B - found previously bought sports bra too tight.
Loving the feel of the pants - 31.5 miles done and no chafing. Result.
Very comfortable you don't even know you are wearing it keeps dry on the warm running days no rubbing does exactly what it says on the box would highly recommend and worth every penny
Absolutely fantastic... so comfortable you don’t know you’re wearing it!! Fully supportive and by far the best sports bra I’ve ever worn. To do a marathon with no chafing was wonderful... highly recommend
I've worn Sportjock running bras for years but decided to give a Runderwear bra a go when I had a voucher for a running shop. I wish I'd changed allegiance years ago! The bras are supportive, comfortable and dry really quickly. I bought 3 in black because the other colours were out of stock and I've ordered another 2 pink ones today!
Bought my first Runderwear Crop Top a year ago and I now have lots. Have tried other brand crop tops but find Runderwear fits well and I don’t get sweaty wet feeling whilst exercising.
I’m not a lady blessed with big breasts so this works well for me.
I love my runderwear money well worth spending
Bought it for my wife and she is very pleased with the fit and comfort during running especially long distances.
Superb product, highly recommend actually feels like you are commando! Exceptionally comfortable a must for anyone who is active.
Lovely soft material and ok support for small ladies, but would get something more robust if your cup size is more than a size D. I bought mine for Gig Rowing and it is excellent for rowing.
Top possibly a bit snug around the ribcage for an older runner but for the first time I completed marathon distance without 'intimate' chafing and blisters.... Happy days
Once again great product, comfortable and lovely to wear, bought for friends as we are running London marathon this year. A few of us in the club swear by this underwear so mow instead of a card I have bought runderwear for them even the other half likes them and wore his for Brighton marathon .... definitely would recommend.
Great quality, soft material that doesn't ride up. Low impact as it states, but this is just fine given my lack of chest. Ladies with a bigger chest would probably find this lacking support. Washes well and dries quickly. Really comfortable.
Very comfortable sports bra, used on a hard personal training season didn’t ride up. The bra comes up high on me which I like, I’m very small on top and should of ordered the smaller size good excuse to order another one
.....is there any chance you can add a bit of padding - I wear a running top over them but at times certain parts of my anatomy are quite visible....?!?!?!?!
Other than that, love love love this brand!
I love this bra! It’s so soft and I bought to wear underneath my running bra as I had awful chafing from all previous bras. I have just done Brighton Marathon and it’s meant I have no sore red raw pathed under my boobs. Love it
Very pleased with this, been thinking about buying for a while and so glad I did. Very comfortable !
Not enough support for me to run in but lovely, comfy top to wear for normal day to day.
I was unsure when buying this product as I never used a crop top instead of a proper sports bra while running and thought it might not give the same secure feeling. Now I never want to wear something else again. It just feels amazing because I don’t feel anything ;) I am definitely getting a few more and would recommend it to anyone. I’m using size s though so I cannot talk for women with a bigger chest size but definitely worth trying if it works for you.
These are lovely to wear, love the seem less construction, but do not provide enough support for me to run with. So kinda misses the point of the brand and purchase. Try Sweaty Betty instead.
I hadn't heard of runderwear before until my boyfriend pointed them out when he received an email from the organisers at Lincoln 10k regarding his race and that's when I saw the link. I looked at the reviews and the comments were really good so thought right I need some of them!!
I ordered the crop top and thong and when I received them I was amazed at how soft and comfortable they are to wear. The thong is perfectly high enough and easy to wear, love the message inside "Don't run commando" the crop top was a little tight at first but now I've got used to it. I definitely will order more, come on ladies try them you won't be disappointed I promise.
Now have two of these. Saw me safely and chaf-free in last years London and now wear them everytime i run, hence reason for the purchase of a new one. Prior to using Runder wear i suffered badly with rubbing from my bra- NO MORE!!!
I have struggled to find a decent bra top as most seem to be too short in length, so they don't cover what they should or are really uncomfortable.
This was perfect from the second I put it on. Fits like a glove, super comfy and a lovely colour. Already thinking about getting another one.
Brilliantly comfortable crop top, hardly know you’re wearing it. Doesn’t dig in under the bust like every other brand I’ve ever tried and is very supportive even without a sports bra underneath (I’m a c cup and thought I’d give it a try). Love it so much I bought 2 more!
Super comfortable and sexy. Just the sizing is tighter in the chest than expected
I received this product two weeks ago and have worn it once for a long run and four times for shorter easy runs. I found the crop to be soft, brilliantly wicking chafe free and very comfortable and unlike a lot of my sports bras easy to get on ... and off ! I do need something slightly more supportive for longer distance and I am looking forward to ordering the new runderwear bra very soon..
Really comfy and easy to wear. Definitely no chafing! I am running quite long distances (Marathon training!) and felt I would be better if I had more support, little bit too soft. Will use this one for shorter runs and more low impact stuff.
This underwear, although more expensive than some is the best I have ever used, no chaffing, exceptionally comfy, well recommended!!
So impressed with this product. It is so comfortable to run in. I now have 3.
This crop top is very comfy ( as are the briefs). I usually buy the highest support level for sports bras and I bought this for comfort rather than support. I wear it in the gym but perhaps I’d go down a size if I wanted to wear for running support.
Can’t really say much more, she did mention that she forgot she had it on that it was that comfy
Very pleased with my purchase, very comfortable and most importantly no chaffing after my longer runs. I will be buying more.
Really happy with my purchase, very comfortable and most importantly no chaffing after my longer runs. Will be buying another one
Comfortable and soft, didn't notice it at all while out on my run. Supportive enough for me. Good fit.
Very comfortable sports bra, didn't know I was wearing it. Quite often I find sports bras too tight even though they are the correct size, this one is perfect.
Really happy with this as a running bra, super comfortable and perfect fit, will be buying more
Love, love, love this top. Really snug fitting and supportive. Forgot I was wearing it it is so comfortable. Will be buying another one and some coordinating pants!
When I received this top I was surprised by its apparent simplicity and I wasn't sure whether it would provide enough support when running. It is actually very comfortable, provides plenty of support for me (I do have a small bust) and washes well. I will be buying another one.
I have never had such comfortable underwear! So soft yet supportive.
I often run long distances of 18 plus miles at a time and this bra is the most comfortable thing I have ever worn! No rubbing whatsoever and very supportive.
Would love to give a review but have been waiting 2 weeks for delivery. No sign yet of when they will arrive!
I absolutely love this crop top. It gives you support but doesn't feel like you're wearing anything and is also rally quick drying which is always a bonus.
Brought for the wife as we both use runderwear briefs and knickers.
Purchased the wrong size but exchanged and communications were brilliant..
I love this top. I’ve already worn it for a couple of very long runs of up to 20 miles and it was super comfortable. I totally recommend this product.
I use mine with a sports bra and there is much less movement then with a sports bra alone.
I always use Runderwear running briefs, which are soft and comfortable, you don't you have them on 5*****.
Although I'm large busted 34FF, I bought the crop top to go under my running bra, it's a game changer for me, ran 10 miles yesterday and perfect skin when I returned. Goodbye to screaming in the shower, any one who chafes will understand this completely! :D Wholeheartedly recommend Runderwear products 100%.
I’ve just purchased another set in white from Runderwear and as usual the standard is consistently high. No chafing or swearing issues. I’ve also got socks which again are brilliant. In terms of fitting I would say they are true to size - I’m a size 10/12 and bought medium top but small pants. Previously bought medium pants but come up a bit high for me. On a practical note everything washes very well and I’m still using the original stuff I bought over a year ago. I’m seriously tempted to try one of the base layers as well. Items were at a discounted price when I purchased so excellent value for money. Really pleased. I also wear for cycling and gym classes too.
Beautiful material and so comfortable to wear. The bra has enough support without making you feel bound up. I use them for my running and also for my high impact fitness classes which I teach so need to feel supported. Knickers have a not there feel about them and as I wear them under 'second skin' style active wear it's very important to not have a VPL. Definitely recommend.
Bought a set for use with activities such as hiking and ski-ing. As I'm quite a large top, it was not sufficiently supportive for me to wear for running without a sports bra. However, brilliant for walking/hiking and other lower impact activities. Very comfortable and breathable to wear though, and the straps do not dig in. The crop top rolls slightly under the bust rather than stays flat., but still comfortable. Underpants, exceptionally comfortable, and brilliant for running and other activities, although they did come up quite large on me. Would consider ordering more.
Having come across Runderwear at the London Marathon Expo, I now swear by these bras. I was at the end of my tether as I got rubbed raw (to the point of bleeding) by most other bras but these have revolutionised my running. Absolutely brilliant.
I'd bought a crop top and pants previously and found the fit and comfort to be excellent. I have a small bust so I find these comfortable to wear while running although I suspect the support would not be enough for larger busts. I recently purchased additional sets to replace less comfortable alternatives and would recommend for anyone wanting something which stays dry and comfortable during runs of all lengths and efforts.
Delighted with the crop top ! Most comfortable I have ever worn
I’d heard a lot of good things about Runderwear so wanted to try it for myself. Well, I was not disappointed. I bought the crop top & hipster pants. Without a doubt, the most comfortable undies I have ever worn for running. I will be getting more as training ramps up as I now don’t want to run without wearing them!
