Review: Excellent. Highly satisfied - I bought it to wear under a Taekwondo sparring helmet, and it worked great for that. So well, that I now wear it when I'm not wearing a helmet as well. I have a shaved head and sweat copious amounts during a typical session. This is very effective at keeping the sweat out of my eyes and face. When wearing under the helmet it is definitely more comfortable than wearing the helmet by itself -- it's very thin and doesn't certainly doesn't retain heat. Under the helmet, though, I can't really feel the cooling effect. Now that I have worn it several times sans helmet during non-sparring training it also is excellent at keeping the sweat off my face, and I can certainly feel the cooling effect. During a one-hour training session, I would typically wipe my scalp/face/eyes with a sweat towel about 15 times. When wearing this, I can get by without wiping the sweat away much at all. When I take it off, it is heavy with moisture and I can wring it out. The label says it is machine washable, but I have just been thoroughly rinsing with clean water after each use, and weekly giving it about 1-2 minute hand wash in the bathroom sink with mostly water and a touch of soap or detergent. It smells as fresh as a daisy. It's only been about 10 uses, so I can't really comment on its longevity or how it will retain it's elasticity/shape/fit after about 10 uses. The fit is fine for me. First time on it feels snug, but it stays in place and after having it on for a few minutes, I forget it is there. I'm pretty hard on it, but so far, I won't hesitate to buy a second one or replace this. I will likely start wearing it when working in the yard or anytime I want to keep my bald-head-sweat out of my face and sunglasses.
Review: Works great, glad I bought 5 instead of 1 (Takes a licking but keeps on Wicking) - The MISSION Cooling Helmet Liner is an absolute game-changer! It keeps my head incredibly cool and dry even in the hottest conditions. Whether I’m just out in the sun, it makes a noticeable difference. It’s comfortable, fits perfectly on my bald head, and wicks away sweat like magic. Bonus tip: soak it in fresh water and toss it in the freezer for a few minutes. If you can handle a short brain freeze, the next 30-45 minutes will be amazing. My riding days might be over, but the yard still needs tending, even in 95-degree heat and high humidity. I highly recommend it for anyone looking to stay cool and comfortable!

## Questions & Answers

**Q: how long do you have to soak it?**
A: No need to soak, just wet it thoroughly under the faucet.

**Q: Are there different sizes or one size?**
A: One size but they fit everyone from our football team to the coaches. Really work well, just don't dry in dry or use fabric softener. Seems that breaks down the material.

**Q: What's the difference between this and the VaporActive model? I would be using it under a motorcycle helmet.**
A: Hello, Our new Mission VaporActive Cooling Skull Cap has an exposed elastic allowing more stretch for a better fit. More importantly it’s a different technology. Vaporactive is our hyper-evaporating technology and our Mission Enduracool (HydroActive) Cooling Helmet Liner is our wet-to cool technology (HydroActive).Please don't hesitate to contact us with any further questions.Thank you,

**Q: It says wring it out. Does that mean completely or leave a little cold water in it?**
A: Depends on what you feel like. I use mine mostly dry under a bicycle helmet to block the sun, but when it's really hot outside I wet it. If it's not rung out some, water runs down out of the cap, which isn't bad when HOT. Or ring out enough so it doesn't, you'll learn what you like/need. I have several now, even one with a flap at the back to protect my neck from the sun when mowing. Wish I had these years ago! I like the white best, but they show the dirt fast.

### ⭐⭐⭐⭐ Best cycling skull cap I've found
*by S***R on July 17, 2022*

(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. CONCLUSION This 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.
