Looking good and feel good
All I can say as to how good these nix feel to run in is that I am now seemingly spending all my spare time trying to source a quality unlined pair of shorts to wear over the top?
With leggings in the cold they are superb and I just want to lose that "extra liner" feel of wearing my runderwear with conventional liner shorts! But as the most comfortable fit ever? Yes undoubtedly this is true and I will be back for many more pairs I can see that!
If someone wants to post any suggestions please feel free? Salomon do a pair of unlined running shorts and they are pricey!
Perhaps Runderwear should get onto that too?
The best underwear I think I’ve ever worn. Comfortable and light. They are my new super pants for my weekend long runs. I’ll definitely be investing in more of these for my summer training and races.
I bought a pair of the merino briefs for my upcoming PCT hike (10th April). So far I've worn them around San Diego whilst preparing for my thru-hike. I've found them comfortable and they seem to manage temperature changes and moisture well.
Time will tell how they perform on my hike but I expect to update my review later on after an extended period of use.
So far I like them and are happy.
Having found Runderwear pants to be really good, I thought I'd try the merino version. Wow! They are so comfortable and, as with the others, no chafing issues at all. I'll be wearing them for the Brathay 10in10 in May. Thanks guys!
These are really comfortable and worth investing a few pounds more in the Merino material. Brilliant!!
Comfortable beyond my expectations.
Excellent quality, no chafing.
These are perfect for chafe-free comfort. I wore these on a recent marathon run and they were so comfortable . I would not wear anything else now when out running.
Der Vorteil von Merino besteht im Temperaturausgleich und der Tatsache, dass es keinen Geruch aufnimmt oder verbreitet. Wenn dann die nahtlose Technologie von Runderwear dazukommt, hat man die optimale Unterhose für jeden Tag. Tolles Tragegefühl!
My now go to running underwear. The merino is unbelievably comfortable and you don't even notice you are wearing it. Perfect product.
Very comfortable on a couple of outings - one in torrential rain. No chaffing and love the "don't go commando" on the inside waistband.
So light and comfortable
I bought a pair ahead of a half marathon. I didn't notice them at all which is the best praise I can give!! The perfect underwear for running.
The first time I wore these was to run the Great North Run and they were brilliant. Incredibly comfortable, chaffing is a thing of the past. I would recommend runderwear to anyone.
Was having trouble finding underwear that was comfortable and didn't make me feel to warm.
Have been wearing the brief in merino wool. Fantastic! Brilliant!
I wear them for everything now exercise , walking , in fact all the time now.
Wash well to and true to size
Excellent product that I thoroughly recommend.
Wore them in a 100 mile race . They were fantastic.. I loved them .
They were really comfortable and supportive and a really good investment. I would recommend them as sport and normal wear.
Does it exactly what it says on the tin
I wore them for a long run on a warm evening and forgot about from the moment I pulled on. Can't say better than that.
Recently I purchased a second pair of Runderwear's Merino Briefs...
I run 4 times a week and go to Crossfit twice a week, for a long time i went commando only because I could never find anything comfortable enough to exercise in..... Runderwear have solved this problem for me. These briefs are so comfortable in warm weather its hard to believe, never feel sweaty 'down there' anymore, looking forward to see how they work when the weather gets cooler.
A huge Runderwear convert.
I'm 6'1" 15 stone, wear size Large for a 35" waist.
Saying I had doubts about the efficiency of these underwear before buying them would be an understatement. However, I have completely changed my mind and I would not even consider competing without them again from now on. Once you start running, you do not even feel you are wearing anything, you do not feel any sweat after hours of running, and no uncomfortable at all with chafing, itching or anything like that.
The size is good. If you hesitate between two sizes, I would recommend you to go for the smaller one.
Purchased for hiking, i am very pleased, purchased more, I am a 33 inch waist and purchased a medium which fitted great
I wore them for two days hiking. Stayed comfortable and fresh for the duration. The sizing is generous. I tend to be between medium and large, I ordered large but another time I would definitely buy medium.
Very pleased I ordered a couple of pairs of these - they are light and comfortable to run in (ran a marathon the other week and no chaffing). Fast drying too.
Great alternative to wearing shorts under long leggings. Much more comfortable
Having tried different methods to prevent chafing on my long runs I tried these having listened to the Marathon Talk podcast when the creators were interviewed.
Perfect fit, comfortable to wear and no chafing. Buying another pair now because they so good.
Having been one of those runners that preferred to run 'commando' rather then putting up with underwear which chafed or remained damp for hours after I had finished running (for those occasions where there were no shower or changing facilities post run)these have been like a breath of fresh air. They are comfortable, in fact unlike my old underwear under running shorts you almost forget you're wearing underwear, and the wicking technology means that you're not sat in a puddle of your own sweat post run.
I sweat puddles on the running & stair machines in the gym, and every pair of synthetic shorts ends up stinking unbearably. Worn underneath, these merinos have fixed the problem. Other gym users are surely grateful, though they're too polite to say it.
I'm a male, 32 waist, and the small size merino briefs are the right size.
Will be the first to admit I was skeptic about these at first... they are quite pricey for a pair of pants.. however having previously suffered with some chafing from my running tights... I thought I would give them a go
They were really comfy and prevented any chafing, I don't even notice that I have them on when running they are that comfy !
I'm converted I won't run without them now !
Excellent product, they feel lighter, thinner and the material stretchier than the original which are still a very good product but for me these are even better. Have had several runs and you can not feel them at all but still get the required support. I have purchased two more pairs since and I could imagine wearing these in summer/hot climates/travelling etc as well as for support. I have not had them long enough to see if they are as durable as the original but time will tell.
Love these. Well made. Perfect fit. Hardly tell you are wearing them. Very comfortable on a long walk. Love the socks to!
