Western Mountaineering - Flight Pants - Unisex

The Western Mountaineering Flight Pants are the go-to choice for winter camping and mountaineering when the mercury plummets and conditions become more challenging. Winter protection for your lower body doesn’t have to weigh 700+ grams; the Flight Pants pack down to the size of a water bottle, are stuffed with 850 fill goose down, and weigh just 360 grams per pair. For added protection against moisture and abrasion, these pants feature Gore® Windstopper™ fabric on the seat and knees. Microfiber shell fabric is utilized for the rest of the garment for moisture resistance, increased breathability and reduced weight. Features include an adjustable waist belt, adjustable ankle closure with draft protection and dual full length, two-way separating YKK coil side zippers with locking sliders.
Western Mountaineering's top-notch construction methods, attention to detail, and years of experience working solely with premium down set them apart from other brands; they are simply one of the world's best down companies, bar none. Based in San Jose, CA, they are committed to manufacturing the in US and Canada. Their down is sourced from free-range mother geese who are never live-plucked or force-fed.

Product Reviews

Absolutely fantastic
Warm, comfortable with the zips they can be put on/off very quickly
I have had in the past many other brands but this one wins the first price
I use them in Himalaya in high altitude in very low temperature and I was very comfortable
Highly recommend Review by Margaret
Happy! Warm! Review by Olga T
Best down pant, super warm
If you are sitting out waiting for your turn on the line and your legs are cold, hanging outside in the cold stargazing or taking the pooch for a walk on a cold Vermont evening then these pants are for you. Worn either over a pair of street pants or over a base layer, these bad boys are the answer to cold legs. I love them so much I ordered another pair..... Sweet!!!!!! Review by rocco p
They're the missing link between the super-light useless synthetics and the I should be carrying an extra sleeping bag huge ones. Like that down coat everybody wears except for the rest of your body. Be prepared to be ridiculed for their fluffy nature until the person ridiculing you tries them and wants a pair. Review by bj
It's like wearing a sleeping bag
super warm insulation layer, perfect for wearing around camp or in extreme mountaineering conditions. The pants are super compressible making them easy to pack, and the 850 down fill keeps them super light. Used them during winter hunts and winter camping. Although they're expensive, they're worth the cost. I recommend them for anyone looking for a solid insulation layer during winter activities. Review by AgainstTheWild
