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.

These features make the Uncompahgre Pant an excellent choice for the hunter who demands serious warmth from packable insulation.

Great pants

These pants are very soft and stretchy so they don't bind or restrict like some pants can. I've worn them in the heat and they breathe well. They have plenty of pockets and my favorite feature is the elastic in the waistband. I generally wore a medium regular in bottoms when in the military and these fit very similar to those. In jeans I wear a 32-34 in the waist and 32 in length. These pants aren't baggy, but they're far from skinny jeans too. I have room to put on my merino base layers under these without being tight or uncomfortable. The feel is so soft that I worry about the durability, but time will tell. If these make it through the season without too much wear and tear I'll update my review and purchase another pair or two.

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!
