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.

Crucial Piece / Fit Issues

This is the missing link once you are done with your hot, pre-dawn hike to your hunting spot. Once there put these on and sit comfortably for a while. Full length zippers are brilliant. Packs very small and surprisingly warm. I find the leg openings entirely too small; can not zip them fully down over my boots. Do not wear these anywhere near brush or briars! The fabric is thin and delicate. Put a small tear in the inside of the knee while straddling over a log.

Uncompahgre Puffy Pant

VERY happy with the overall feel of this puffy pant and packability! I’m 5’7” with a 32” waist and the Medium fits perfect! It will be perfect in inclement weather where I can toss a Gor-Tex pant shell over them if it’s really nasty and glassing is needed. Would suggest these to everyone!

Awesome insulation piece!!!

I've been itching to try some of First Lite's gear and finally pulled the trigger. I purchased the uncompahgre pants to use as an insulation piece for several hunting styles. The obvious one is for during the sitting portion of big game hunting. I haven't used them in this application yet, but after wearing them, I'm confident they'll do just fine.
The other style of hunting I purchased these for is for underneath waders while duck hunting. These are perfect for this application. I was constantly battling sweat while walking to the duck blind with lots of insulation under my waders. The uncompahgre pants work perfect with the full side zips on the side. They give me the option to throw these on after the walk-in to avoid over-heating.
I'm 5'9" and 185lb. the mediums fit good

Great supplemental piece

This is a great piece to add to your gear. Super light, packable and easy to get on. Good for the deer stand down to 20 degrees w/ base layers and other pants, I don't think they'd be warm enough below that temp. Love the articulated knees and extra room in the seat so the waist doesn't pull down exposing your lower back if you're sitting. Looking forward to bringing these on a Western hunt in the future, I'm sure they'll be perfect.

Just what I was looking for

I wanted a insulating pant that was low on bulk and big on warmth. I like to hike in deep in the whitetail woods so most of the other whitetail systems where to bulky for me. I throw them in my pack then when I get to my stand I slip them on over my regular pants.
