Fabrics

The beauty of pure custom work is the ability to fine tune a product exactly to the customer's need.
At Nunatak one of the many choices you can influence is the fabric used for your sleeping bags or jacket.
We have a number of different materials and colors in stock at all times. These all have varying properties and weights, and will have different applications.
To help you on the way understanding what is best for your Nunatak product we have a little introduction to each fabric later on this page.
Feel free to give us a call if you want to learn more.


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 treatments.
This modern arsenal of fabrics for down shells far outperforms previous generations ability to breathe and repel water. Please note that we do not re-sell our materials by the yard.

 
Fall 2008 Fabric & Color Choices
New 0.8 oz Pertex Quantum:


The new .8 Pertex Quantum is a fantastically light yet strong fabric, featuring a 20% mass reduction over our trail proven Quantum 1.0. Despite its tinfoil thin stature and low weight, this new contender for the lightest possible yarn is still hardcore outdoor worthy. A notably lighter hand and 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.
Time will tell if this is the best Pertex fabric yet, as the 1.0 Quantum is well regarded and very stout for the weight. We still recommend the 1.0 for most gear we build, but those shaving grams will find the new .8 a significant step up in performance.

NOTE: An additional material fee applies to all 0.8oz Quantum orders:

Sleeping bag, quilt and jacket shell and liner upgrade:
Half bag and vest shell and liner upgrade:
Balaclava and all booties shell and liner upgrade:

 

$25.00 each, $50.00 both sides
$20.00 each, $40.00 both sides
$10.00 each, $20.00 both sides

1.7 oz Epic by NexTec:

Pumpkin Orange, Ocean Blue, 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 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.

1.0 oz Pertex Quantum:
Black, Gunmetal Blue, Brick Red, Sage Green

This 1.0 oz/sq. yard ripstop nylon shell is a super breathable 20 denier material from our friends at Pertex. The best choice for down gear requiring the utmost breathability and lightest shell weight. Just a hair heavier than our .85, this is the lightest most breathable Pertex fabric ever. As with all fabrics from Pertex, a DWR+ and exceptional softness translates to high lofting down sleeping bags and down jackets.
1.3 oz Pertex Microlight:

Fire Engine Red, Sunflower Yellow

A light and breathable shell material weighing in at 1.3 ounces per square yard. More breathable and a bit less water resistant than the EPIC by Nextec, this Pertex rip-stop nylon is world famous for its durability and supple hand.
The fabric is significantly stronger than a .85 oz/sq. yard nylon, yet has the soft feel of traditional taffeta.
The Pertex special DWR+ (Durable Water Resistance) treatment will outlast and outperform other typical DWR treatments

 
1.0 oz Nylon Taffeta:

Black

Our silky smooth 20 D nylon taffeta is built especially for the lining side of ultralight down gear. This is the perfect liner for both a down expedition parka or 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.
