Too Tight

  • Familiarity:I returned this product before using it

I love GORE products and was excited about these super awesome-looking arm warmers. Unfortunately I had to return them because they were way too tight in the upper arm and elbow. I always wear a small in everything, and although I never tried the Medium, I think those would have been too long and too baggy in the lower arm. The quality is fabulous, but the fit was wrong.

Good fit and solid wind stopping

  • Familiarity:I've put it through the wringer

A very nice set of arm warmers. I got these on sale during this summer and have used them for many early morning and fall rides. For reference, if it helps, I'm 5'10 and wear 33" sleeves on my fitted shirts and the large size fits me well.

Unfortunately we don't have a size chart and gore does not have a listed size chart. Generally for the arm warmers you size them in relation with your jacket/jersey size. If you wear a medium jacket/jersey you would want to go with a medium warmer. If you need any more assistance feel free to chat in with one of our gearheads and they should be able to assist you further

Is the entire arm warmer (other than the cuffs and band at the top) made of Windstopper? From the pictures, I can't tell if the upper arm is a different fabric.

The WINDSTOPPER is paneled into the areas that generally recieve the greatest wind chill effect.

Snug as a Bug

  • Familiarity:I've put it through the wringer

These are one of the most comfortable and snug arm warmers I've owned. The ergonomic paneling, seams and grip are quite perfect. Getting them on requires some effort but after that it just blends in with your physique and performance.



I'm female, 121 lbs and bought the Gore arm warmers in size S. They are too tight at the top and between the tightness and the grippiness, they feel pinchy and uncomfortable. So, I just don't see how a guy, no matter how lean, is going to be happy in a Small. I'd think about going up a size if you are considering buying these.
