FitsT4 Sports Active Sweat Wicking Bike Helmet Liner Cycling Skull Cap

Great little skullcap for use under a bicycle helmet. I'm 5'10", 170lbs with a shaved head, and this fits perfectly. Kept me cool on my last two 30+ mile rides in the GA sun, with temps in the mid 90s, and kept the sweat out of my eyes. No idea on longevity or stain resistance as I've only worn it twice, but so far, so good. i do wash it in a mesh laundry bag, and hang to dry. Will probably buy a couple more to rotate.

Works very well.

I initially purchased a white, Pearl Izumi, skull cap from REI to protect me from the sun. While the Pearl Izumi product was great, I wanted a second skull cap, but also wanted to spend less money.I purchased this product and hoped for the best. Honestly, it works just as well as the Pearl Izumi product. It fits great under my cycling helmet too!Save some money and purchase this product!

I just took the fully bald plunge but need to protect my head as I am super outdoorsy. The plan was to wear this under my MTB helmet to protect me from having my helmet pattern burnt Into my skull. Not only did it protect my head, it also kept it cool overall and wicked really well. Worked perfectly.

Does not absorb sweat at all not as adviertised would not buy again

I got this to try as a cheap alternative to either Pearl Izumi, Castelli, etc. On a warm day this is just as good. But when the heat turns up to about 85+, thats when this cant compare. There is no wicking property. At the end of the ride, my Pearl Izumi or Castelli caps come off damp but this one comes off drenched which when riding is not so comfortable. Also, on long rides past 25 the sweat starts to drip down. So, if you dont cycle in excessive heat then this is a cheap alternative but if you cycle into the heat of the summer (and humidity) I would stick with the name brands.

I've now purchased 3 o f these. I wear them in a small bakery instead of a hairnet. Great at wicking sweat and stays put on my bald head. Great product!

I have a 58.5 cm head and can usually wear a Medium or Large bike helmet. This sun cap has a snug, but not uncomfortable fit on my head and fits well underneath a bike helmet (usually requiring one extra 'click' on the size adjuster for proper fitment). It serves it's desired purpose of preventing sunburn through the helmet vents and does so without making my head feel noticeably warmer on hot days.
