Rated 5 out of 5 by from If i could live in these..... I bought these pants to wear when touring Iceland, knowing I would be camping and sleeping in a tent and that I would probably want something to go from evening to night or night to morning in. These were the perfect pant for that. Some nights I slept in them, some days I wore them while travelling between places. They are comfortable, roomy enough to move easily but without having gaps to let cold air in, have nice pockets that don't stick out and look pouchy and are just the right level of warmth. I can see them being a favorite pant for lounging about in during winter. The material stayed clean and did not attract fluff and look dirty like other dark fleece can.

Rated 5 out of 5 by from Perfect for lounging at home or around a campfire I had a previous pair of REI fleece pants (can't remember the name of that particular model but they lasted for over a decade and they were great) and needed a new pair for camping (and chilly SF bay area fall/winter nights). When I found the Tetons they were perfect, lighter in weight than my previous and beloved fleece pants and a much better cut and fit. They're nice and toasty and VERY comfortable. I'd recommend them to anyone who is looking for cozy lounging around or for sitting around the fire on a chilly night camping. Thanks REI!

Rated 4 out of 5 by from Well made REI brand. Normal fleece. Better attention to some details and seems better built. Tapered at calf and ankle. Meant to give good under layer without bunching up or flapping around. Will be anxious to try it out Jan 2017 snowmobiling in Yellowstone as warmth base layer!

Rated 1 out of 5 by from Bad design I tried these on and they fit well, material is soft, however the logo is embroidered on the knee so it rubs and catches on my knee whenever I bend my knee.

Do they (REI Teton Men's Fleece Pants) have a fly?  If "yes," hook and loop, snap, zipper, button closure?  Thanks.

Asked by: backwoodsloafer
The Teton Men's Fleece Pants do not have a fly.

First, is the Teton being discontinued? Second, are the only pants they list (32" inseam) a children's size, or actually "men." Have they ever had, and/or will they ever have anything longer than 32" inseams? Who on earth wears an XXL 32" inseam. Thnx

Asked by: thebostonartist
As of November 2016, these pants are not being discontinued. They are men's pants, not children's. We have carried similar pants in a 34" inseam in the past but at this time do not have plans to carry them in a 34" inseam.

Does anyone know how much these weigh in a large or XL?

Asked by: HikingBear
​Size large weighs 11 ounces.

Saw you had no plans to carry in 34" ...WHY?... As large as the company is, do you really not have enough sales of this length to warrant offering it?
