I'm bald and trim what little hair I have I cut short. It's easy to get sun burn through the vents in typical helmets and sunscreen runs into your eyes. A skull cap is a must and this one works great. I previously purchased the version without the visor and purchased this one when it came on sale. Does wearing a skull cap make your head hot? Not at all, I soak it in water before a hot ride and keep it wet during the ride. The evaporation keeps my head cool, better than no cap at all. The visor extends over the top of my sunglasses and reduces glare especially in the early morning or late evening.
Was looking for a version of sun sleeves that would be a bit stretchier than my other sleeves (Specialized) and these fit the bill. They aren't as stretchy as arm warmers, which I am guessing is a function of the sun-shielding material, but they are an improvement for sure. My old ones tended to bunch at the elbows and would bind when I bent my elbows. These don't bunch much and allow for more movement, while still having good sun protection. The fabric also do seem to do a good job of cooling.
I was looking for some additional gloves and since I've found good quality and fit with Assos I decided to try these because i wanted a slip-on with some palm padding. Not having to worry about velcro snagging on sun sleeves is great. I was worried the amount of palm padding was too little but it is just right and in the right places. The mesh doesn't let the hands get warm on those sunny days. They are not the easiest to remove but my Castelli gloves with velcro aren't the easiest to take off either. Do wish that Assos offered these in more color choices.
