Strange sleeves

I am used to wearing fitted clothing, but the sleeves on this shirt had an unusual, constricting seam between the elbow and the wrist that made this shirt uncomfortable, especially when you extend your arms.


Perfect fit and comfortable during warm weather. Quality fabric!

Very good travel and sports warm down top!

Easy to pack. Surprisingly warm for a lightweight top.

Very comfy

Nice material, breathable and keeps you dry. Great fit around the shoulders and chest.

Not as fitted as I expected

Comfortable for running in quite hot weather (30°C/86°F) and high humidity (above 80%). The size is not as fitted as I expected for the chest and abdomen, but it is for the forearm. I'm 172cm and 69kg.

Love the comfort, sleeves a bit tight and body length runs long (size XS)

I love the fit and the comfort of the fabrics, just the sleeves is a bit tight. You'll struggle a bit to put it on.

This product has great features

Very nice, comfortable, easy to move in. People loved it on me.

What I was looking for

Comfortable, good fix, good quality, just what I was looking for
