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

Did the job and put up with the intense sun and heat on the beaches of Manta in Ecuador 🇪🇨! Just don’t get attached to the logo as mine peeled off day one! I’m a sweater so this thing really mitigates the annoying discomfort of sweat just pouring down your face! Wet it and cool it or just refresh and wet it under running water and it really help cool you down!

Fits great, airy and snug against my head! Breaths well and very comfortable! My head is a 73/8! Covers down to my ears doesn’t cover them!

Works great but a little tight.

I've been a a huge fan of Mission products ever since I got my first cooling towel. This helmet liner is perfect for practically any helmet to help keep you cool. It fits nicely under my bike helmet as well as my airsoft helmet. I also found it extremely useful for VR headsets, as they can get pretty uncomfortable when you start to sweat. I actually expected for my headset to fall off because the helmet liner wouldn't have a good trip on the padding, but it held just fine even with constant head bobbing. The only thing I don't really like about it is the size. It's just a little too small for my liking. I would have preferred it to be like a beanie and have it go over my ears completely, but it only covers them partially and the seam is uncomfortable against my ears. Still, this is a very good product and I definitely recommend it.

I have been using head bands and sweat caps for years. I use them biking, working out, yard work. Honestly, this is my favorite. Wish I would have bought one sooner. Fits my head perfect. Total comfort. Although there is no terry cloth band, it seems to manage my sweat better than my head bands with the absorbing cloth. And yes, it does disperse the sweat and make you feel like you have a mild cooling sensation. Especially under the fan at the gym. The moving air really makes the cooling sensation nice. Anyway, this seems to be a pretty high quality sweat cap. It is thin enough for me to wear under my helmet when biking, or just going for a walk. Maintaining it is easy. In my experience, sweat and salt can ruin elastic and some cloth, so I hand wash with a bit of laundry soap after each use. It dries quick and you are ready to go again. To sum this up, I am a believer and really enjoy this cap.

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.

This cooling cap WORKS...when working outside in the heat and humidity it really does keep my head cool under a hat. What impressed me the most was the innovative cooling technology used in this helmet liner. The fabric is comfortable to wear, even on a bald head. All I have to do is soak the cap in water, wring out the excess, and put it on under my hat. The instant cooling sensation is incredibly refreshing and helps keep me comfortable for hours...then just wring out the sweat, snap it 3 times and put it back on and it feels 20 degrees cooler. It has a snug, yet comfortable fit that stays securely in place under my hat, even during heavy working conditions. The stretchy and breathable fabric ensures it doesn't feel restrictive, feels like I don't have it on. As a heavy sweater in the heat, the cap's moisture-wicking properties are a godsend. It effectively absorbs sweat and moisture, preventing it from dripping into my eyes and obstructing my vision.

Fits great and I use it under my golf hat. Protects the hat from those nasty sweat stains.
