EPGU Men's Outdoor Sports Jacket - Lightweight Waterproof Windbreaker for Hiking, Running & Camping - Perfect for Adventure Travel & Outdoor Activities

Comfortable and breathable. A little tight on my nose, but I can breathe fine while wearing it. Kind of makes me feel like a ninja.... Each of the 4 came in its own resealable plastic bag. They looked like they would be small, but they have a good deal of elasticity. So far I really like these. I wear it around my neck and easily pull it over my mouth and nose when needed.
