GORE WINDSTOPPER

GORE WINDSTOPPER

They do this with an ultra-light, ultra-thin membrane which blocks wind while allowing interior moisture vapor to escape. Your microclimate will be so cozy and inviting, you could probably timeshare it out.

Rated 4 out of 5 by from Beautiful bag and backed by an awesome team of people at WM My relationship with this bag can be best summarized as love at first sight. Unfortunately, the first time I used the bag I noticed that the stitching (though beautiful and perfect everywhere else on the bag) was loose in about a 1 cm section at the base of the collar, and it was slowly leaking down. I called WM and they were super nice and helpful. They told to mail in the bag on their dime (using their UPS account), and they would fix it and rush it back to me in time for a trip a month from now. I have never felt so good after dealing with a customer service department. I still have 100% confidence in the bag, and now I also have 100% confidence in the company and their warranty.

Rated 5 out of 5 by from pretty awesome bag on an ill fated (we had to hike out to closest road after getting dumped on by 20" snow over night) Pemi traverse last winter this bag was awesome. I am 6'6" 185lb and always cold in bags in the winter. This is the first bag that I was legitimately warm in the middle of a northern NH winter.
