Wore on a late October Wyoming Backcountry hunt where temps ranged from 0-20°F overnight and in the mornings. Light, compressible and easy to put on upon arrival at the glassing spots for extra warmth. Paired very nicely with 30 degree bag overnight in low single digit temps in the tent. Never was cold, once. Huge fan of these pants.

Game changer! You don't know what you're mising until you've tried them. I always new I wanted to try puffy pants since they started to get more popular. I was skeptical about the 3/4 length with these but I'll be honest, they really grew on me. Late season when its wet, cold, snow, mud whatever nasty conditions, these works flawless when wearing gaiters. They are very warm and very light also. Super easy to pack and easy to throw on over wet boots keeping them clean to throw back into your back when you take them off and start moving again. No complaints here, they'll be with me late fall through early spring no matter what now.

These pants are very fragile. Ordered them on March 15, 2021 and wore them during a blizzard chasing turkeys in mid-May (Montana). The first time I wore these pants the underbrush cut a 1x1 inch tear in my lower right leg above the cuff. Pretty shameful a piece that cost so much money cant even withstand the simplest of brush. Needless to say, I had a ton of filling flying out, even though the hole was very small. I went to make a warranty claim and Sitka does NOT cover tears in their products. Guess I will throw a patch on them until I can find a better solution. Plus they are loud too, I would NOT recommend these pants to anyone, there are much better options on the market. Sitka struck out with these big time. I suspect the other Kelvin Lite pieces I have are just as vulnerable and weak.

I'm 5'10 and 175 lbs. I have a bunch of Sitka gear. In pants, I have the Mountain, old style 90%, Ascent , Territory and even an old style Kelvin lite. I was so impressed with the updated version of the Kelvin down lite hoody I went for a pair of the Kelvin 3/4 lite pants too. The quality is great and the design clearly sheds weight, it is definitely more compressible than the full length Kelvin lite. They also should be keep you warm. But the design features feel over done for me and I decided to return them. If you are looking for the absolute lightest warmth to weight ratio you can, this is a great piece. For me I would rather have the little bit of extra weight and slightly less compressible for a little more versatility. I really did not like the style and the zipper location might have its advantages for venting while sitting but then reaching into you inner pockets is difficult. I'd like to see a full length version of the Kelvin lite pant with the new down and mapping but the zipper straight down the side. I think for most hunters except those that care about shedding an ounce or two would feel similar.
