SS.skinFoilSpring/Fall_s7 Body Insulator

Maybe the Assos SS.skinFoilSpring/Fall_s7 Body Insulator has a handle that will tie your tongue in knots, but it's not actually that complicated if you break it down. Allow us: SkinFoil is Assos' name for its body-hugging, temperature-regulating baselayers, which are constructed with no visible seams to eliminate chafing and enhance mobility. A blend of nylon and polyester moves moisture quickly away from your skin, and the compressive fit helps support muscles to decrease fatigue. SS stands for, reasonably, short sleeve, which is pretty self-explanatory, and Spring/Fall denotes — ready? — the seasons in which the midweight skinFoil is designed to excel. Finally, the s7 suffix indicates that the skinFoil is part of Assos' newest line, which takes the already legendary Assos ethos to the next level.

  • A temperature-regulating base to get you through shoulder seasons
  • Nylon and polyester blend move moisture away from your skin
  • No visible seams makes for a chafe-free fit
  • Compressive construction is ideal for supporting muscles
  • Body-hugging fit is ideal for layering under your go-to jersey

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.

Great base layer, but needs more length

Assos base layers absorb persperation better than any others, but with all their clothing they should be made longer. I'm 5'5", 150 lbs, and got the large, but still it barely extends beyond my belly button.

Should have bought two

I've put it through the wringer

Love this garment. Use it for more than cycling as a base layer. Good for any cold weather activity. Arrive comically small but stretches to fit. Love it.

Assos Does It Right!

Top quality fabric and great design makes for a great fit. At 5’10” and 158 lbs. with a broader upper back I tried the medium. While it could work, it’s just a bit too tight. I prefer snug without extra fabric and the large is perfect for my frame. It wicks moisture very well. Will buy another.

Hands down this is the best base layer if worn since I started cycling almost 7 years ago. I have both the short and long sleeve versions. Top notch quality and great fit. Usually pair it with arm, knee warmers and gilet for my morning rides. Very seldom do I have to use a jacket in San Antonio TX. Will be purchasing both versions in the near future.

Invisible base layer - Perfect choice

I've used it once or twice and have initial impressions

I wore this to ride the Gran Fondo New York. Temperatures were expected to be in the 40s while waiting at the start on the GW Bridge and in the 60s during the ride. I paired this base layer with the ASSOS arm warmers, the GFNY Biemme race jersey, and alternated wearing a Castelli rain jacket. The base layer performs exactly as advertised. When I was putting in an effort on the climbs, the wicking properties kept me cool and dry. When descending Bear Mountain at 41 mph, it kept the chill off my chest. The fit is spot on - fits snug without binding. I asked for and received advise from the CC Staff and they were absolutely correct in their suggestion on this base layer being what I needed given the anticipated temperatures. They know the product and gave great advice.
