I have to replace the cheap liners in my helmets regularly because they do not hold up at all after you wash them even if you do it carefully. This is a product that exceeded my expectations and makes me wonder why manufacturers don't give you this kind of smart quality product in the first place.
4th Sweathawg...soon to be 5
I purchased my first helmet liner a couple years ago hoping to keep the sweat at bay. The only reason it didn't work for me is because my husband nabbed it to see if it would help stop the sunburning of his "shall I say hair-challenged head" from the air vents in the helmet. It solved that issue perfectly! Since then I've purchased a winter hat that works great for cross country skiing, a cap insert, and yes, another helmet liner for myself. It works excellent! Going to try the x2 version next for the upcoming hotter days of summer. Sweathawgs Rule...I highly recommend.
