The is the big sibling to the JMT Jacket. With warmer insulation, more features and a roomy fit, the APEX insulated PCT Jacket excels during adverse weather conditions, or in any circumstance where moisture can infiltrate the insulation. 


The warm puffy to wear during cold activities; short recovery breaks; freezing nights and mornings in camp; or as a boosting layer for sleeping.


Starting with a bare bones layout the PCT can be configured with or without an extensive feature set.

With 8 basic sizes as starting points, one can further customize with sleeve and body length adjustments.

Synthetic Fill

APEX by Climashield, a superior continuous filament synthetic insulation, is the choice here.

We have 3 weights available, from light (less warm) to heaviest (warm, but bulky). It's hard to attach a temperature rating to each, however we feel the most efficient balance of weight and warmth for 2-3 season mountain use in the continental US (and the Alps) is the 2.5 oz/yd. Folks who easily get cold might disagree, and for you we have 3.6 and even 5.0.

We also offer a few variable applications of fill. The option is to go down one or more levels for the sleeves and hood if the 3.6 or 5.0 is chosen. This will reduce weight and bulk in a fashion that makes sense: more insulation for the core, less for appendages. 

The APEX specs:

2.5 oz/yd Climashield APEX - 85 g/m - light, compact, 2 season
3.6 oz/yd Climashield APEX  - 122 g/m - in betweener, 3 season
5.0 oz/yd Climashield APEX - 170 g/m - bulky, light 4 season use


The PCT Jacket can be configured with different shell choices, each in a limited number of colors. These are ultralight fabrics for folks who want the lightest, but realize that abrasion and tear resistance is minimal. Listed below from lightest to heaviest:

10d ripstop. Smooth, comfortable and about the lightest material possible for practical shell use, at 0.67 oz/yd. Very breathable with minimal moisture repellency. Moroccan Blue, Brick Red.

7d Robic. A waterproof/breathable material based on an ultralight, yet relatively durable 7D base fabric with amicro porous coating. Altogether the total weight ends at a respectable 0.74 oz/yd. The Robic is useful at shedding water with a HH (hydrostatic head) of 1000mm, while providing enough vapor transfer for mild activities (good breathability). Bright Blue, Black, Dark Olive and Dark Grey.


The chart below outlines the many options for sizing the PCT Jacket. The cut is generally aimed at providing a roomy fit, easily accommodating layering and backcountry utility.

If you choose the bulkier, warmer 5.0 oz/yd fill - expect a less roomy fit and a stiffer garment.

Either way, since these are built to order we saw no reason to limit the choices. 8 general sizes can be combined with custom sleeve and back lengths. Have at it!


Skaha pullover

I just received my Large Skaha. Im 5'11 and weigh 180. It is well made and the sizing was great. Perfect for my backcountry fly fishing trips.
I couldn't have asked for better customer support while deciding on various options and I am so glad I ordered a semi custom jacket rather than going with an off the shelf jacket.

Thank you Nunatak!

Works as planned.

I have the 85g/m in the sleeves and
122 g/m in the body. I planned this to be good for camp chores to a few degrees under 0C and a bit beyond if need be. So far it has coped easily.
Wee bit over 320 grams. Elegant in design. Succeeds as planned.


Winter warmer update

Since my first review I have used my Skaha APEX jacket for about 6 months and it is awesome. On windy nights photographing the moon in 25f, around base camp in 18-30f even the occasional walk short walk when snowing. It has always kept me warm and snug.
Thanks again for a truly great jacket.


Toasty at 37f

Skaha APEX jacket
Body length is good, not being too short, and the cuffs don't ride up when raising my arms. The 13" zip makes it easy to get on and off. Elasticated hem which keeps the drafts out, could do with an elasticated collar to stop heat escaping. Climashield APEX 5oz filling is a little bulky like most Four season synthetic tops, having said that it fits well over my base layer and not that bulky under my waterproof jacket.
The outer shell is Grey Robic Ripstop fabric with a breathable micro porous coating. The Robic is useful at shedding water with a HH (hydrostatic head) of 1000mm, while providing enough vapour transfer for mild activities (good breathability). The inner material black taffeta and this is where the insulation is stitched in. This is the lightest version of the pullover style jacket, with the medium weighing 353g, 12.5oz.
You can of course specify the fill, back length, collar, pockets, hood and several other features.
I used this jacket on a recent overnight trip on the North Yorkshire Moors. Windy at 15-20mph and gusting 30mph with hill fog rolling in.
Around camp I was warm and dry and when I turned in for the night I left the top on over my base layer under my quilt. It soon became too hot so removed & added to my stuff sack pillow. Unfortunately, the temperature did not drop below 37f overnight, so the jacket did not reach its full winter status. Will be submitted to further use as winter draws on and the temperature drops.

Really impressed with it, very well made and the fit seems spot on, everything I wanted and nothing more.

Thanks so much for getting it to me in time for my Arctic Sweden trip.

WOW, super impressed!

I got the the 5.0 Apex and It is so lofty yet so light! Superb quality, looks great, feels great. Special thanks to Jan for working with me on some custom details- I really appreciate it! Look forward to ordering from Nunatak in the future they are a first class operation.


Skaha synthetic

An email from a customer, talking about initial impressions:

Just letting you know the jacket arrived today with two weeks to spare before my trip!. I am absolutely thrilled with the result. It's a beautiful, warm jacket and the finished weight came in at only a hair over 400g!!

I'm hoping to do a little write up for backpacking light when I get a chance.

Please pass on my thanks to the team. Superb work!



From an email we got:

Received the jacket yesterday- looks great! I was surprised (pleasantly) how much loft the 2.5 Apex has- wow :) I'm hoping to bag Stuart Peak tomorrow, the jacket will accompany me.
