Overview
Highlights of the Nunatak Skaha Apex:
- Best warmth-to-weight ratio of all jackets in this review series. With the 5 oz/yd (170 g/m) insulation option, the Skaha Apex only weighs 15 oz (425 g). That’s 30-40% less than other similarly warm parkas.
- Even though the jacket costs less than its closest competitors, it is custom-made in Utah;
- Choose from six levels of insulation, three fabrics (want a highly durable fabric? – Ask for the HyperD or EPIC fabric), a variety of pockets, and select the width, length, and sleeve length that best fit your body.
The Skaha Apex is for anyone who wants a custom fit jacket or the highest warmth-to-weight ratio.
It can take Nunatak up to six weeks to make your jacket. If you are in a rush, consider the Patagonia Micro Puff.

- $225 base price with a hood;
- $260 and 9.9 oz (281 g) as tested;

Review Context
We tested this jacket as part of our Synthetic Insulated Jacket State of the Market Report (to be published on March 25, 2018), which compared fifteen of the best jackets over two years of hiking, climbing, mountaineering, packrafting, backcountry skiing, and ski mountaineering.
Description of Field Testing
The author used this jacket on a two-week ski mountaineering expeditions in the St. Elias Range, a two-week skiing-packrafting expedition in the Alaska Range, a five-day mountaineering trip in Southeast Alaska, and on a variety of overnight and day trips. The author’s friend purchased an identical jacket (different only in size and color) and used it for a month-long rock climbing expedition in the Arctic. Combined, we have close to 90 days of use.

Description of Custom Options Tested
The base Skaha Apex costs $200. The jacket we tested cost $260, weighed 9.9 oz, and was configured as follows:
- Size medium (+$0);
- 85 g/m insulation (+$0);
- 0.66 oz/yd (18.7 g/m) Membrane liner fabric (+$0);
- 0.8 oz/yd (25 g/m) Quantum exterior fabric (+$0);
- Hood (+$25);
- 2” extra sleeve length (+$5);
- 2” extra torso length (+$10);
- Elasticized “lycra stretch banding” cuffs rather than unfinished cuffs ($5).

Companion forum thread to: Nunatak Skaha Apex Review
The Nunatak Skaha Apex is our highest rated windproof synthetic insulated jacket. Even though the jacket costs less than its closest competitors, it is custom-made in Utah. We highly recommend the Skaha Apex to anyone who wants the either the best fitting jacket or the highest warmth to weight ratio.
Thanks for the thorough review!
I have a Skaha Apex jacket that I’ve been using about one year now. Â It’s also the lighter Apex insulation. Â This jacket has tremendous loft (at first I thought Jan may have sent me the wrong jacket), but it weighed 10 oz on the nose (Men’s Large), so it simply lofts well. Â No surprise, with the high loft comes warmth- I think the warmth to weight ratio is incredible with this jacket.
Mine is Robic and thus far I have found the fabric to be highly water and wind resistant. Â I agree with your assessment on breathability- this is not the jacket for high aerobic pursuits. Â With that said, I actually like the kangaroo pocket for rests, camp, glassing- all rather static activities.
I agree the jacket lacks the refinement of offerings from Patagonia, Arcteryx, etc, but I kind of expect that from a cottage shop. Â Certainly room for some improvement in that area, but much of the refinement seen on other jackets is simply eye candy- this jacket functions outdoors as it should.
In regards to the hood, I prefer a smaller hood as I don’t ever use a helmet. Â I do wish that in addition to the face closure adjustment, it had adjustment at the top, rear of the hood. Â It doesn’t add much additional weight and provides for a much better fit.
I choose this jacket to use on the 2017 Bob Marshall Open- wanted something light and warm, but more resistant to moisture than down. Â The jacket exceeded my expectations.
I didn’t purchase the jacket for elk hunting, but it went with me almost every trip this past fall. Â When combined with a base layer, a heavier mid-layer (R1 like weight) and windshirt, I was able to sit and glass for extended periods of time in quite cold conditions (more so than I would have thought). Â With that said I’d be better served with a warmer jacket for elk hunting and I’ll probably go with the same jacket in a heavier insulation for this next fall.
This is a very nice warm and light jacket that should fit nicely in someone’s quiver.

This jacket really shines at the heaviest insulation option. So impressed with the numbers (warmth:weight ratio), esp. if you’re willing to ditch the extra features and heavier fabrics, and just include the hood.
Reminds me of the Cocoon UL philosophy: warmth:weight, everything else be damned.
Mike, your photo at the Basin Cr Cabin! Ack, the memories of that place. Spent a few nights there sleeping on the porch recovering from long-distance / bad weather misery. It’s a nice refuge. Happy times. But a hard-sided Nalgene for the BMWO? I’m impressed ;)
Ryan- the morning after a 4-5 hour “nap” :) Â I think that must be John’s Nalgene (my Platy is off to my right)- he’s tougher than me, also uses a Stone Glacier pack!
Thanks for including our Skaha Apex in this review.
I am happy it apparently scored up there with the offerings from leading manufacturers with much more refinements in their products.
We are taking all Max’s observations to heart and will try to address any that were not entirely positive.
At this point we are no longer focusing on developing lightly insulated down jackets in the sub 8oz category. There’s simply no point to going that route anymore.
We see more warmth for similar or lower weight in Apex products, with better performance in damp conditions over the closely quilted, lightly filled down competitors on the market.
Thanks for this thoroughly researched and well illustrated article on what looks like my next cold weather parka.
Good to see that tests reveal, yet once again, that Climashield insulations are just about the most durable in terms of retaining loft after repeated compressions. This is why the US Army’s Nautick labs chose a version of it for military sleeping bags.
I’d like this parka more if I could order with a full length zipper and two “hand warmer” pockets. But if not I may still order it as a pullover. And the customizable fabric shell and arm and torso lengths are almost too good to be true! At last.
“Combining the Skaha Apex with an active insulation jacket, such as the Patagonia Nano Air Light, is a viable setup for fast and light winter travel in moderate temperatures (10’s and 20’s Fahrenheit). Carrying only 20 oz (567 g) of moisture-resilient insulating layers is truly outstanding!!”
this is my go to combo through all of shoulder season and most of winter; in colder weather I substitute Nunatak’s 2.5 Apex pullover w/ their 3.6 Apex jacket- this layered over Patagonia’s Air Light is extremely warm when stopped or at camp (with just a couple of ounces additional over the pullover)
