ROCKBROSMen's Cycling Cap Breathable Sun Proof Helmet Liner Hat

I purchased two of these caps and could not be happier.For sizing purposes, I'm a big guy (6' 2" & 230#) and it fits fine with not discomfort for long periods of wear.I've been using a couple similar caps for over 10 years and it was time to replace them. Shopped a little and landed on these.I wear the cap backwards under my helmet to keep swear out of my eyes. I've used both several times on long (2-hour plus) rides in heavy humidity and the work like a charm. Plus the bill can be turned up to hold the back of my helmet in place or down to keep some sun off my neck.I was not familiar with the RockBros brand before this purchase and the quality is great. Good robust design I plan to wear for a long-long time.

It fits my large head, comfortable, and doesn't deform after a wash.

Product arrived different than in photos. The photos for the color I chose did not have a logo on the bill of the hat and the ones I received does. These hats do fit very well and are lightweight. I’ll be keeping them, but wanted to caution anyone purchasing this color.

I've battled sweat dripping into my eyes while riding for years. I've tried skull caps, Head Gutterz, Halo Headbands, different helmets, smearing vaseline on my eyebrows. They all saturate and fail at some point during my rides and start dripping sweat from my balding head into the inside of my glasses and eyes. I finally gave in and bought a cycling cap, figuring I would not like it because it would impair my forward vision when down low or in the drops.I was actually pleasantly surprised by this cap. First, it fit a little better than I expected under my helmet. With the brim down, I can push it further up on my forehead or lower down to adjust how much it blocks my upper peripheral vision. I was able to get my helmet to sit comfortably over it. I still end up having the center peak of the brim impede my forward vision a little bit when riding in an aerodynamic position, but it wasn't totally awful. I could live with it.Now for the good part- the brim of the hat directs the sweat drips to the front of the brim where they fall off, instead of into the inside of my glasses as with other sweat solutions, head bands or just a helmet alone. It isn't perfect- when I am hammering along at 20+ MPH the wind still blows the sweat drops back onto my glasses, but at least it is on the outside where it is easy to wipe or wash off while riding.The hat stayed reasonably cool when soaked with sweat as well. It does keep some heat in compared to wearing nothing, but again, it isn't awful. It rinses out easily after a ride and dries quickly. I won't comment on the style, other than to say that is the main reason I waited so long to try out a cycling cap and went through every other sweat handling device first.Overall, 5 stars, because it keeps the sweat out of my glasses and the price was reasonable. Despite the little problems I have with it, I have yet to find a better sweat control solution. Recommended.

You need a pretty big head for this to get a decent fit. It's ok under my helmet and I use it to block the sun on late afternoon rides and to soak up the sweat from my head, but it's pretty large and not comfortable to wear on its own. Much better for me under a helmet - and I'm 6'0 and 185 pounds.It's holding up well, but I would have preferred something with a better fit.
