Say goodbye to sweat in your eyes

We're all in the sweaty skull crowd. After all, the perspiration has to go somewhere. The only debate is how we deal with it. Plenty of us understand the appeal of a cotton cycling cap, but it has its limitations -- the brim is hard to fit under the helmet, and the cotton stays damp after absorbing moisture. When you have to deal with sweat, take a good look at the roboFoil Cap from Assos.

It's a cap designed for both the modern age and modern helmets. It's an ultralight cap made from two different synthetic materials. The cap features an ultra-thin design with taped seams to both minimize volume and to guarantee that the cap won't create any pressure points on the skin. Overall, the construction makes the roboFoil easy and pleasurable to wear under your helmet.

The two bands down the middle of the roboFoil are the lightweight, wicking SPX fabric. The side panels create ventilation, which is why they're made with a wicking polyester mesh.

The Assos roboFoil Cap is available in the color White Panther. Sizes are Assos-specific -- 0, I, and II. Size 0 fits 48-53cm head, Size I fits 53-58cm heads, and Size II fits 58-63cm heads.

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

I've never got great use out of my Oakley glasses - they always end up sweat stained through the ride when things get down and dirty. A cap (I like the Rapha ones) seemed to hold back the sweat a bit.

Used it last weekend including a 17km mountain ascent - I still wasn't dripping by the top!

After 5 hours it was still wicking, very impressive.

love it

  • Familiarity: I've put it through the wringer

I got this hat while ago , and since day one , I loved it ! I wear it all year long , from cold spring tru late fall. It is very cool addition . If you , like me , like long rides , what I found out is , that , helmet with this hat feels very comfortable. Feels like , u not actually wearing a helmet. It protects your head from sun , wind , light rain , and of course , very stylish. Very durable. Easy to wash.

love it

Does the stitching bother you at all? I am a little concerned about the stitching that goes all around the seam.

Recently got this beanie, and am really liking it. The stitching doesn't seem to bother me (I was afraid it would), but the little LOGO BUTTON in front did! My helmet presses against it and is uncomfortable. SO? I just wear it backwards. Problem solved.
I have no idea how this works, but I've been wearing it in VERY hot weather, and I take it off and somehow my hair is DRY where the beanie was, and wet around the edges. Amazing. Finally found the solution to helmet head!
