I am outdoors a lot during the winters in Colorado, and I own several balaclavas, from lightweight to heavyweight with Gore Windstopper. This Chaos-CTR Howler balaclava is the best of them all for several reasons:

-Windstopper fabric is soft and flexible unlike Gore Windstopper products which are effective but stiff;
-Mouth covering is more effective than any other for ease of breathing as well as no fogging of glasses or goggles, a big plus;
-the nape goes down farther than any other balaclava, more than covering the entire neck area; it's essentially a windstopper neck gaiter built in;
-the hood hinging means it will come down to your eyebrows, leaving only a small open area for your eyes, or it can be lifted incrementally to expose your forehead, front of head or entire head, and it doesn't make the facemask portion tight on your face as you adjust it. Rather ingenious;
-unlike many balaclavas you don't even know you have it on; it's roomy where it needs to be and snug where it needs to be.

Really, this is the perfect balaclava, and at $15 it's a bargain. Chaos products are high quality outdoor gear.
