Uncompahgre Puffy Pant

37.5 Active Technology Insulation


Color/PatternFirst Lite Cipher

Whether you're glassing late season goats, layering for a long sit in the stand or sitting around a chilled, backcountry camp, the Uncompahgre Puffy Pant provides the hunter with packable insulation for the lower body. At a mere 18 oz., this highly compressible layer features a very toasty 100 gram, 37.5 synthetic insulation. Full side zippers and Velcro waist clasps mean you can get this pant on or off in seconds without taking off your boots while allowing you to layer them over your pants if desired. An exterior DWR and reinforced seat resist moisture and tears while on the move or sitting pat. These features make the Uncompahgre Pant an excellent choice for the hunter who demands serious warmth from packable insulation.

Fervent fit

I just got my new pair of uncompahgre puffy pants. I have not had them in the field so this review is mainly for sizing. I am 6’ tall and I way 185-190lbs. I wear a 32-33 waist in jeans. I was not sure if I should go with the medium or large. I ended up going with the medium as I did not want them baggy.( I where large in all my first lite jackets and shirts) The medium pants fit me perfect. I tried them on with long johns and a standard cargo hunting pant underneath. They are perfect length and perfect width in the waist and leg. Can’t wait to try them out in the field.

adding suspender loops to mine

i wore these once last year in tree stand in the teens, with wool tights, then these, then a goretex shell pant over them. didnt get cold for a few hours. the downfall here was im in between sizes (l and xl) and the velcro didnt snug them down on my waist enough in the xl so i could not walk in them without them falling off me.

mother in law is adding suspender loops for me

4.5 Stars

These pants are amazing! The reason I called this “4.5 stars” is because of their durability. I tore mine slightly within the first week but I will say that I was walking out in them because I was too lazy to take them off and I got what I should have expected. They are super hot and not meant to walk around in. They pack down so small and take up little space in my pack. Get where I’m hunting, put on and zip up quick, and I’m toasty warm. My ultralight thermals, obsidian pant and the uncomphagre pants keep me warm down to about 40 degrees Fahrenheit. If I put on heavyweight thermals I’m good down to as cold as I’ve sat in, which would be around 20. I would imagine if I had a heavier weight pant than the obsidians and wore heavy thermals, these uncomphagres would allow me to be toasty regardless of temp. I plan on picking up the catalyst pants this year and use my obsidians during bow season only. I am very glad I bought the uncomphagre puffy pants!

Weight: 160lbs - 170lbs
Location: Alaska
Primary Use: Spot & Stalk
Fit Comments: Although it performs well, fit isn’t quite there. I wear medium, with my actual size being 31x30, they were a bit too large and would slide and shift off my waiste. Even when I had them over my pants and base layer. The Velcro was a nice touch but doesn’t work well. It was also very large at the rear where it looked like I was wearing a diaper. It needs belt loops. And should fit better overall.
What I needed for my Spring and Fall hunts

Pants are light weight and very warm...Enough insulation to protect from late August winds at 7000 ft hunting for sheep. Warm enough to sleep on top of my sleeping bag at 40-50 degrees and perfect for camp.

These pants haven’t left my pack

I bought these for western back pack hunting but I’ve found that They are perfect for my style of whitetail hunting. They allow me to wear a light outer layer pant on the outside on my long walk in and when I start to get cold I can pull these out of my pack and warm up. The full side zips are so handy. I can quietly put these on with little effort. They have been great this fall for all day sits and below zero wind chill. Just like my puffy coat, these pants have replaced my bulky fleece pants. Excellent product!!!!
