Cooling Helmet Liner - Lightweight & Breathable - Cools Up to 2 Hours - UPF 50 Sun Protection - Machine Washable

I living in southern Louisiana, in 90 degree heat 80% humidity, this cooling liner works perfectly. I sweat profusely on my forehead and top of head/hair. I got this mainly to keep sweat out of my eyes while at work, it has worked great so far the 3days I’ve used it. Some reviews said the band is a little tight, I have a small to medium head and it fits perfectly for me. I wear it under a ventilated baseball style hat and safety sunglasses, I don’t find it to be any warmer than without the liner. It feels like really good quality without being too thick.

Been using this liner for my gym workouts lately, and it’s been great so far. It easily handles sweat through my entire 1.5-hour training session. I’ve used other headbands before, but they usually start failing halfway through. This one stays effective and comfortable the whole time. Highly recommend!

(edit: New Update added at the end Nov. 2024)Me: mostly bald road & MTB cyclist who sweats a lot from the head. I give you this background and the next paragraph to help people like me who read through great reviews of a product and purchase it based on those reviews only to find it doesn't work well for me.I've tried all sorts of sweat management equipment to keep sweat out of my eyes and off the inside of my glasses while I'm riding. The Sweat Guttr does OK but interferes with my helmet. The Halo headband quickly saturates and then starts dripping into my glasses. Skull caps trap the heat in and make my helmet feel like a furnace and I usually end up taking them off.Despite my previous bad experiences with skull caps, I decided to give this Mission model a try based on their marketing claims. As the review title suggests, this product definitely outperformed every skull cap I've tried previously. It wasn't a miracle worker, however, and it did eventually allow sweat to drip.THE GOOD*It didn't feel hot. Heat wasn't trapped in like other skull caps I've tried. The evaporation kept my head at what felt like the temperature it would be if I wasn't wearing any covering. This also wasn't dependent on airflow, so it wasn't hot when riding slow in the woods on a MTB or fast on the road with lots of airflow.*Comfortable- fit well with all 3 of my helmets and didn't move around during the ride.*Kept sweat out of my eyes. My first ride with it went great. It was a lower humidity day and I took the road bike out for a 2+ hour ride at an easy pace. I started with the cap dry as it wasn't hot enough to need the cooling right out of the gate and my head would wet it quickly enough. I only had two drops of sweat fall into my glasses the entire ride. Even better, the cap pushed the front pad of the helmet where the sweat dripped from beyond the top of my glasses, so it landed on the outside rather than the inside like usual, so that was a win. The second ride was a hard hour in maybe 65% humidity and lower 70s temps. The helmet and liner saturated after 49 minutes and started dripping regularly (again on the outside of my glasses at least). Without the liner I estimate I would've reached this point after about 25 minutes. The next test was a medium effort for an hour and a half at 80% humidity and mid 70s temps. I hit saturation at 43 minutes and sweat continued to drip profusefully for the rest of the ride. I will note that the sweat was dripping from the saturated helmet pad in front, not from the skull cap. Maybe a different helmet design could improve this.THE BAD*Didn't do much for mountain biking. High humidity in the woods, low speeds, little wind and hard efforts made for a drip fest. I couldn't tell any difference between wearing this and wearing nothing. It probably delayed saturation a little, but not by much.CONCLUSIONThis performs well enough to become my go-to sweat management for warm weather rides. 4 stars overall. Mission will need to get its tech team busy designing a new super-material that can evaporate the sweat faster than I can produce it to create the perfect cap that earns 5 stars from me.Update Nov. 2024: For those who have the same sweat dripping problems as me, I suggest giving cycling caps a try. I got one and like it better than this skull cap for sweat management. The brim of the hat draws the sweat out to the front and lowest point when my head is down in a riding position and gets the sweat drips far enough out that it doesn't drip inside my glasses. At road speed, the sweat can still get blown back onto the outside of my glasses at times, but this is easier to wipe away than the inside, so I rate it as an improvement over every other sweat management system I have tried so far. Some caps are made of a similar material to this liner that breathes fairly well.

Purchased for use under my full face motorcycle helmet. it is thin enough that it doesn't make my helmet fit any tighter. Definitely makes wearing a helmet much more comfortable especially in this 100 degree Texas Heat. Highly recommend!

Exactly what I needed. Not necessarily a "doo-rag", but I desired something that would "soak" up my head sweat instead of it being soaked up into my hat and hat lid.The description in the product details impressed me; when talking about moisture, wicking, perspiration, and evaporation. As it convinced me, I wanted this "cap" to absorb my head sweat rather than get sweat lines and sweat marks into the lids of my hats (I am one of those that "overly sweat"). I would say that it reduces that happening about 98%! So it worked for me for the most part, just a small bit of sweat was able to get absorbed by the lid, but not to any serious or permanent stain degree.I did lose this, so I ordered it again, and found that, straight out of the packaging, the new cap was rather loose. Then I remembered that after reading the tag (then and when I first had the original), you HAVE to machine wash it in cold water first to "activate" it (somehow)! Trust me, if you don't do this, the cap doesn't quite fit "tight" and work right. And this is a great cap, so you would be seriously missing out!

Unfortunately this helmet liner doesn't seem to work for my needs. I have to wear it under a helmet that has limited ventilation. It would seem the liner needs a fair amount of air flow. It requires moisture evaporation to keep the liner cool, it just takes more venting then expected for it to work. It was a chance I took and it doesn't work for that particular application I needed it for. I'm still holding on to it to see if I can use it in a different capacity but as of right now the only time I've tested it was with that helmet and it was unsuccessful.I soaked it in water, followed the directions to "activate" the cooling effect and it was cool on my head when I first put it on, and for breaks, but it just felt like I was wearing an extra pieces of lycra fabric under my helmet and actually made me hatter then it did cool my head. For breaks it was nice I could take it off and snap it, then it would cool a bit but my break times are fairly short so I know it cooled for about 20 mins but that was the longest I really felt it's effects in my experience.So I can't say for sure it doesn't work, but make sure you are wearing this under a helmet that gets decent air flow for it to really be efficient. Otherwise it would be good as just a cooling cap with no helmet. The fabric is soft, some of the stitching lines a re a little annoying if they rub your head, but not terrible. It didn't seem real tight, it was snug but not tight, and it didn't have a smell or anything to it like some of those cooling towels have.

Tight flat fit.

Works great for 8 hour braaps at over 100 degrees

これはいいよ

E' leggerissima.Non ci si accorge di indossarla.Tiene veramente fresco.La consiglio come sotto casco ma anche per chi lavora sotto il sole.

Works. Feels cool when sweating,

Great idea and it certainly makes a difference on a hot day

Très rafraîchissant et ne blesse pas comme d'autres produits mal conçus pour être mis sous un casque. Malheureusement le blanc est très salissant. Y aurait-il moyen de l'avoir de noir ?
