The only good solution I've found

I'm a heavy sweater. No really, I sweat a lot! 25 degrees f outside mountain biking in just tights, a long sleeve jersey & I'm drenched, it's been a nightmare. I got fed up with trying to ride my bike with sweat all over my glasses, I just could not consistently see the trail due to streaking. I've tried just about any solution commercially available or otherwise but nothing worked until I tried a Sweathawg Helmet Liner X2. Did it completely eliminate my problem? No but let me explain... No matter what I use to help control sweat, sooner or later it is going to become saturated & begin dripping sweat onto my glasses (prescription, btw -can't see without them) With nothing in my helmet, I could get maybe 10 minutes into a ride before the drips started. With the Helmet Liner X2, I've gotten to 1.25 hours in 70 degree f temps before I need to address the situation. When I begin to see drips starting to form, I stop, remove my helmet & wring out the Helmet Liner X2. It's amazing how much sweat comes out of the thing! After doing so, I'm good for another 1.5 hours or so which is fantastic!

I couldn't be more pleased with this product, it has allowed me to quit worrying about what I couldn't see on the trail & allowed me to ride faster & safer than I've been able to in the past. Many thanks for a great product!!

The liner performed as advertised. Gets a little warm on sumner days in Southern Arizona. Using the liner there was no sweat on my sunglasses during my 23 mile mtn bike rides. Great product and light weight.
