Note: Assos clothing has a very slimming, anatomic cut, if your build is less than slim or if you like your fit looser, go up in size.

How to Measure:
For best results, take measurements over your underwear.
Measure around the widest part of your chest.
Bend to the side and measure around the place where your waist bends, keeping the tape a bit loose.

Worked Brilliantly for Me

I've used it several times
True to size
Size Bought
6` 0"
200 lbs

To begin: I'm 6'0" and right at 200 pounds and wear a L-XL II in this Assos shirt. I also ride in South Florida, so the conditions are pretty extreme. I wear the long sleeve version, and for me I feel noticeably cooler when I wear it. When I open my jersey a little, it makes an even bigger difference (I've since this purchase bought an Assos Millie jersey that I also love). The sleeves are a little long, but because they're so tight you don't notice it. This is probably a function of me being a larger rider relative to my height. Cool shirts and undershirts are a tricky thing. Your mileage may vary, and you might not like the idea of wearing the shirt under your jersey. For me, riding in 80-90 degree temps every day, I love it. I've actually bought a second one so I don't have to wash them every day and I can rotate them.

Very weird sizing on the new SkinFoil

I returned this product before using it

I had the previous generation long sleeve skin foil base layer for Spring/Fall and it fit like a glove in a size I. Went ahead and ordered the Summer long sleeve version in the new generation skin foil in exact same size and the fit is totally different/off/bizarre. Ok in the abdomen and arms - in fact the sleeves maybe even a tad short and definitely snug (moreso than the previous generation). But the upper shoulders and neck feel 2 sizes too large and sort of billow there while the lower half fits snuggly. I get that Assos tailors garments to fit in riding position as opposed to standing in front of a mirror and the billowing does chill out a little in a riding position but not enough to make any sense. I am not a rail thin dude and for a cyclist am pretty muscular in the shoulders and chest relative to my waist size so this fit makes zero sense. May exchange for the size 0 but would be worried the sleeves will be waaaay too short and tight then. We will see. Scratching my head on this one Assos...

I have similar filling. Upper arm has strange sizing.
