Fabric shell choices for Nunatak 2015

One of the many choices you have is the fabric used for your sleeping bags or jacket. Our modern arsenal of down shells far outperforms previous generations abilities to breathe and repel water which are both essential traits for performance down wear. We have a number of different materials and colors in stock at all times which have varying properties and weights, and thus different specialized applications.

The unique fabrics that we offer are designed specifically to contain and protect goose down from the elements. They are breathable to permit body vapor to escape and have durable water-resistant or encapsulation treatments.

Here is information on care of our gear. Please feel free to email or give us a call if you want to learn more about what we build or how to care for a Nunatak Item you already own.




0.8 oz Pertex Quantum:

Sage Green, Black, Orange

.8 Pertex Quantum is a fantastically light and strong fabric, featuring a 20% mass reduction over our trail proven Quantum 1.0. Despite it's thin stature and low weight, this new contender for the lightest possible yarn is still hardcore outdoor worthy. A notably lighter hand, smaller packed size and a slight increase in vapor transfer in an already highly breathable material pushes this fabric to the top of the field. Same DWR+ treatment as featured with all of our mountain class Pertex fabrics.


1.0 oz Pertex Quantum:

Black, Sage Green.

This 1.0 oz/sq. yard ripstop nylon shell is a super breathable 20 denier material from our friends at Pertex. This is the best choice for down gear requiring the utmost breathability, maximum durability and minimal shell weight. As with all fabrics from Pertex, the robust DWR+ and exceptional softness translates to high lofting down sleeping bags and top level performing down jackets.

1.7 oz Epic by NexTec:

Orange or Black.

EPIC by Nextec ™: A revolutionary shell material for down! At 1.7 oz/sq. yard, this polyester microfiber features a unique and very durable water resistant silicone fiber encapsulation. The result is a highly breathable, extremely water resistant, soft and pliable material that allows for excellent loft. This fabric is a quantum leap in performance for a down shell material and is actually made stronger by the silicone encapsulation. The best choice for jackets and bags requiring the maximum water and abrasion resistance.





Epsilon 1.55 by Duro
Our new multicam 1.55 oz./ sq. yd. rip-stop nylon fabric balances lightweight with excellent tear strength. The NanoSphere® liquid repellency makes for an ideal sleeping bag. The fabric has been processed to reduce air permeability and increase down-proofness, which also creates excellent wind-break properties for a bivy. low IR
1.0 oz Nylon Taffeta:


Our silky smooth 20 D nylon taffeta is built especially for the lining side of our ultralight down gear. This is the perfect liner for both a down expedition parka and an ultra light summer down quilt. This new taffeta is 30% lighter than previous generations of material and boasts a superior DWR finish. A demanding role for a shell material, this strong nylon remains nicely breathable with a fine weave and a soft hand. At 1 ounce per square yard it is durable enough for the long haul, yet light enough for top level performance. We stock this in black only.




Zeta 1.9 by Duro


Zeta multicam is a breathable and water repellant lightweight polyester. It is soft and supple and is face treated with a durable water repellant finish. Zeta is a quiet and lightweight fabric best suited for hunting down jackets. It also has low IR properties for night time utility.
