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.

Pants and Jacket that you need

This pant and jacket combo kept me in the stand longer than anyone else at our camp by at least 2 hours. One day while sitting in the stand it started coming down in a mix of rain and snow, it was 0 degrees Celsius (32 Fahrenheit) and kept me toasty warm and dry with the water just running off, only issue I had was the button broke on the pants, thankfully Duke at customer service was awesome and fast and I should have my replacement before my next hunt. All in all this is a great pant and jacket and you should get it if you're thinking about it.

Perfect piece to put on when you need to get warm in a hurry. Stop waiting to get it, these are amazing and a steal for the price. Don’t break brush in them.

Great pant but not terribly water resistant

Very warm pant and did great in -20 degree weather and 30+mph wind walking through knee deep snow for several hours to pack out an elk! Only downside is they seemed to absorb quite a bit of moisture and took a long time to dry out. They also ripped on the inside of the knee while hiking over a lot of deadfall but I’ll try to figure out how to patch them. Otherwise, terrific pant for severe weather and kept me warm for about an 8 hour pack out.

Great insulated pants

I was concerned to order the U pants because I could not confirm based on the reviews whether or not I was going to get a good fit. Well, I am very surprised and extremely happy. I am 6'3" Tall and weigh 195. Typically 34"×34" everyday pants. I ordered the Large and they fit GREAT. Do not be concerned about the waist, many complaints about no belt loops, but the way these pants are designed, a belt is not required. The velcro in the sides can be adjusted accommodate larger or smaller waist by approx 2" either way. These will be used for Whitetail stand hunting, western big game glassing and fit perfectly under my rainsuit for fishing. Asl always, well done First Lite.

Not just for western hunters........

It's not listed under the whitetail section but it should be. Definitely a great option for early season north eastern whitetail hunting. Compresses down to nothing so it takes up little space in your pack but provides excellent warmth for the chilly morning or evening sits in the stand. The Uncompahgre jacket and pants have been in my whitetail day pack since I got them because the weather in New England is as unpredictable as the winning lottery numbers.

First Lite, don't sell the Uncompahgre short as a great whitetail option for those chilly sits.
