3-4 season baffled down pants or knickers.

The basic configuration is a simple design with an elastic drawcord at the waist, unfinished leg bottoms, no pockets. Build upon this with side zippers for passing footwear through, suspenders, etc.

The cut is moderately roomy to allow for layering and to preserve the down loft. Warning: These will make you look fat!


Wow, these are warm!

Awesome customer service in making sure I got what I was looking for in a puffy pant and these exceeded my expectations. I can't believe how warm these are. The sizing is spot on and I can't find another set of pants that comes close to the warmth to weight ratio of these pants.


Kobuk down knickers

Have had a Kobuk Knickers in Quantum/Epic for years, it has held up well.
Very light, very warm.
Mine has buttons on one side: I can pull it over ski boots and under a shell without taking anything off.


Great cold weather companions

I ordered the Kobuk hoodie and pants last spring, and they had their first real test at Dolly Sods WV recently. Temperatures dropped to -12F with wind chills down to -30F. I used the Kobuk pants (and parka) around camp, and never felt the need to hit the tent and sleeping bag early. The combo easily extended my 0F sleeping bag down to the -12F reading that night, and would be good much lower than that. Impressed, and the degree of warmth for the weight is incredible.

3-4 season down pants or knickers.

Product Options
Pants Style
Adjustable Elastic Waist and Plain Jeans Style Leg Opening
Adjustable Elastic Waist and Elastic Leg Openings. Best Option for Knickers.
Waist Size
Size up when in doubt or when worn over more than running shorts/long johns.
Here are both pants and knickers options. Actual inseam length will measure shorter as insulated pants generally ride lower; and to protect the leg opening from wear.
Shell Fabric

These are the Classic breathable shell options, typically listed from lightest to most durable. Please go to the Fabric Page for help choosing the shell material.

Liner Fabric
10d Black Taffeta - Lightest, most breathable
20d Black Taffeta - Durable
Down Type

We use 900 fill power goose down, certified responsibly sourced.

Hyper-Dry moisture resistant down will help combat the effects of perspiration, misting tents and damp air. Nunatak products made with Hyper-Dry down will have a slight increase in bulk over those made with untreated down.

Pant Leg Zipper Opening
Located on the outside of the lower leg. Size the zipper to allow footwear to pass through. Trail running shoes need only 12 inches, while boots may require 20" zippers. Consider full length separating zippers for ease of use while skiing, mountaineering, doing winter sports, etc.
Pant Suspenders
Removable. Installed suspenders adds 15g
No Suspenders
Add Suspenders
Down Overfill
Adding overfill can prolong the life of the down, help maintain loft during moist conditions, boost the temperature rating by a small amount and keep the down volume from shifting. The amount depends on the product, the size and the rating.
No Thanks
Overfill evenly throughout
Plus quantity overfill throughout
Stuff Sack
Our stuff sacks are pretty dope, but current weight saving trends in ultralight circles eschews this once crucial item. So, opt out and save $ while also being very current.
No stuff sack
Yes, please include a stuff sack
