Great top

I brought this top 1 week before the London marathon and did 1 run before the big day and had no issues when running the 26 miles. Perfect fit just need more colours as was hard to spot

Thank you for your feedback on the Short-Sleeve Base layer. Congratulations on the London Marathon, We are so pleased to hear that you are loving it as much as we all do. I will pass your feedback onto the team about more colours!

Overall is a good baselayer

Fit & Material:
I weight around 55kg & 160cm tall. I ordered the smallest size but it's still big for me in the stomach and waist area. Hence it doesn't wrap tightly across my body. In the arm & chest area, it fits perfectly. The material is nice and I didn't feel any stitching at all.

Usage Experience:
I ran in the rain, under the hot sun, and high humidity jungle. There's no chafing in all my runs but it can get really hot during a humid run.

It doesn't chafe in a long run. When it gets really hot I'll just easily spray water and it'll control the temperature. Excited to try in a cold-weather environment.

Quality & Comfort

As with all of the Runderwear kit the quality of the product is clear to see as soon as you take it out of the packaging but the fact it’s a good fitting top Is a huge part of running kit as you really do need to feel as comfortable as possible when your clocking up the miles.

The material is breathable but think enough to keep you warm when running, definitely I’ll be using this in autumn and winter months as a top on its own or base layer when 🇬🇧 cold snap hits and the head-torch comes out! 🥶

Stuart Allen | Brand Ambassador
It is a great bit of kit!

I've just gotten back from my first run in Runderwear's new Short Sleeve Base Layer and it was a real joy! It's well fitting without being restrictive and super soft. Although the weather was warm the top was breathable and the fabric being moisture-wicking meant I was comfortable throughout. A fantastic addition to the already great range of kit by Runderwear!
