Easy to carry with you if you need it or not!
Tuck it in under a zipped up jersey or jacket and air leaks are sealed off.
A must for any commuterrecreational cyclistrunner who want to survive the trip in comfort.
Purchased the product to use a neck warmer, the fact it can be use as a bandana or cap is a bonus. It works well for me when the temps are 50 degree F and below. Very soft material that doesn't irritate the skin.
