I’ve tried various things from runderwear so the next was the support running bra!! I couldn’t recommend it enough!! The only tip I got from the designers themselves and lovely reviews was to go a cup size up!! It worked a treat!!

The bra is comfy, even on longer runs and fits extremely well even though there is no underwire! I wouldn’t be without it now!

Anna said: 50k ultra marathon- no chaffing!

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.

Jen F said: Very Comfortable!

I bought these as my first pair of Runderwear. I am so happy with them! They were very comfortable to wear while running (5 miles+ at a time) and kept things cool. No riding up, no tightness around anywhere. I found them to be true to size as well. I ended up buying two more Runderwear after testing these out.

Tom K said: Rundawear reviews

Whilst not used extensively to date, everything about the product and service seem very positive to me so far.

The product is light, comfortable and cosy enough; but noticeably less sweaty than traditional options, even in this hot weather. Size might be on the smaller end of average so if i doubt go for the larger. They are nice and flexy too though.

Good work Rundawear, i'm off to buy another pair.

Sarah Hocquigny said: Good product

These have been pretty good so far, comfortable, good fit, and no chafing. I had a discount code from the Leeds 10k but it is a bit pricey for just one pair, especially as most people who run regularly would likely want to have more than one pair.
