The Skaha is an upper 'mid-weight', fully baffled box construction zip neck sweater. It does not have sewn-through seams.

The fill weight represents over 50% of the total, with 5.6 ounces of down in the size medium

The resulting warmth makes this jacket a legit choice for shoulder season high mountain backpacks.


The fit is roomy to accommodate layering, especially compared to the popular form fitting, closely quilted down jackets. 

At night the Skaha can boost the temperature rating of your ultralight quilt, thus saving on weight otherwise invested in redundant insulation


We build the Skaha with simplicity as the overriding design parameter.

The standard front closure is a YKK #3 pullover style half zipper, backed by a draft tube. 

The options for pockets on the Skaha UL includes the hand warmer 'muff' style exterior pocket, and inside chest pockets. 

We make the Skaha both with or without a hood. The hoodie version features an integrated standard sized insulated hood. 

Hood and bottom hem are adjustable by shockcord.

The sleeve ends can be done in a number of different ways. See menu choices below.

Down Fill

The Skaha UL is insulated with 900 fill power goose down, available in regular untreated or moisture resistant Hyper-Dry down.

Both options are RDS certified responsibly sourced down from ethically committed harvesters.


10d Ripstop Nylon. Smooth, comfortable and about the lightest possible for practical shell use, at 0.67 oz/yd. Very breathable with minimal moisture repellency. 


A fairly accurate depiction of the fill weight is in the main chart below. The totals are representative of the lightest fabrics and several key features: 10d shell and liner, integrated hood and front pocket, standard sleeve ends, no overfill, etc.


Roomy fit to protect loft and accommodate layering. Cut with a straight torso and large sleeves for ease of passing over head and shoulders.


Skaha UL Down Sweater with hand warmer pocket

This is a great piece. I say that even though both plastic rivets used for reinforcement at the top corners of the hand warmer pocket broke off within 15 days of use. It's warm, fits well, is super packable, and light. I was skeptical about the lack of elastic in the cuff, but was surprised to find I prefer not having it. Other sweaters in this weight range that I looked at had approximately half the loft and were often sewn thru, whereas this one is a fully box baffled work of art.

Original Hoodless Skaha

I spoke to Jan and had my Skaha modified with 900 down plus and additional added down insulation. I also requested the Epic shell and a hand warmer pocket. I have worn the jacket every day for the last six months and it goes everywhere I go. I love this jacket and Jan was amazing to work with. His advice was invaluable and I greatly appreciate what I consider true customer service. I will be ordering more from this awesome company.


Alpinist & Skaha sweater

Thank you for both the down sweater and sleeping bag. I recently returned from 8 days in The Tasmanian Wilderness and was absolutely satisfied with both products. The other three on the trip were very jealous of my sweater. We all needed to carry light gear because there were no food or fuel drops. All the others left their down jackets behind because they were too heavy. Not mine. So light. So warm. I love it . Also very impressed with down quality in the sleeping bag. The first few nights were warm and with previous sleeping bags I would have been perspiring and sticky but I layed it over me with zipper open and it was perfect. The last four nights the weather turned with a cold front and I snuggled in fully zipped up. Perfect. I think your down quality must be really good because in the past I have always had to wrestle with too hot or too cold all through the night. I had the best sleeps thank you. I am ordering a down sweater for my husband so I will be asking questions over next 2 days about the order before you are out of contact. Thank you again.


Skaha UL

From an email we received:

After a lot of research, I decide that a Nunatak Skahah was the best UL down jacket I could find. I am tall and lanky (6’1’’ // 165lbs.) so I talked with Jan over the phone and we arrived at a couple of modifications in the fit (size medium body, size large sleeves, 1.5" added to the bottom hem). When I received the jacket the fit was excellent! I was also very impressed with the membrane .66 which seems to be very durable given its weight. I also really appreciate the fit of the collar/hood—it can seal up really tight for warmth, but still doesn’t feel constricting or restrictive.

I opted-in for hand-warmer pocket with my jacket, because in the past I have always liked having, well, a warm place for my hands. However, if I got this jacket again, I think that I would consider not get the hand-warmer pocket. I find the I don’t use it too much actually, and the added insulation makes the belly area of the jacket a bit bulky given how much loft the jacket already has. If anything maybe I would get two small non-insulated, pockets just to put small things in like a headlamp or whatnot.

Overall, I am very pleased with the service, materials and workmanship of this Nunatak jacket, and hope to invest in some more of their products in the future. Thank you Jan!

My most recent Nunatak order was the Skaha down sweater with extra fill.
My experience with Nunatak is one of complete satisfaction.The quality and construction is excellent and the materials used are superb.
I recommend Nunatak without reservation.

Thanks for such an awesome (and pretty) set-up! It served me well on the Lost Coast Trail this much so I slept with it when I got back home! I'll definitely be ordering from you guys again in the future.

From an email we received on 08/16/2016:

Hi Jan, My down sweater arrived a couple of days ago, and I just wanted to send you a quick note to say how much I love it! The custom fit is excellent—just as I was envisioning and I really like the feel of the shell fabric. I’m also very appreciative of your attention to detail in the design and the quality of your workmanship. Can’t wait to get outside and use it soon. Thank you so much! A...
