Body-skimming. Short, 8.5cm inseam.

A high, wide waistband that sits flat, and a short cut that stays close without compressing.

The difference is what it is made of. Cotton and modal do not turn slick and synthetic the moment you warm up, which is most of the reason people spend a workout adjusting their shorts.

Train in them. Then keep them on.

Two pieces or more: free shipping, applied automatically at checkout.

Size 10 UK medium fits perfectly, but it’s much more snug, I prefer a loser fit and bought a large as well. It’s definitely up to preference. I just prefer my clothes feeling not too tight.

Love these biker shorts! The material is so, so comfy. I've worn these to the gym and running and I'm happy to say that they pass the running test! They're pretty short and ride up a bit when running, but the cut is very flattering. I'm 165cm tall and 95cm hips and the M fit me perfectly!
