Ultralight Shell fabrics:

 15d - 0.8 oz Pertex Quantum: Black, Sage Green

your-image.pngyour-image.png

This .8 Pertex Quantum has a distinct large square ripstop pattern and a slight increase in vapor transfer compared to Quantum 20d. It is also nearly transparent, especially in sage, causing a change in color when filled with goose down. Same DWR+ treatment as featured with all Pertex fabrics.

Large ripstop grid, of about 1/8" squared.

USE: Shell appropriate on most ultralight quilts and jackets. These classic 15d fabrics have long been the go-to choice among backpackers aiming to take the step into the realm of ultralight gear. With normal care the 15d Quantum offer reasonable durability, yet is noticeable lighter and less bulky than 20d fabrics. 

 10d - 0.67 oz Ripstop Nylon: Dark Grey, Moroccan Blue, Brick Red

your-image.pngyour-image.pngyour-image.png

An ultralight 10 denier ripstop nylon that is breathable, calendered, and down proof. It offers excellent wind/water resistance, a soft hand, and tested downproofing in both lab and field use. At 10 denier and a finished weight of 0.67 oz/yd, our 10d ripstop is one of the thinnest/lightest nylon fabrics on the market today. Transparency makes it change hue with down fill.

USE: Shell and/or liner for projects requiring the lightest weight and minimal stuffed bulk. This is a specialist fabric, for users willing to adjust to a compromise in durability and tear strength. Well suited to the the protected life of a quilt or sleeping bag. The careful user can choose it for jackets and pants. 

The lightness of our 10d Ripstop translates to superior lofting ability of 900+ fill power down.

20d Pertex Quantum: Black, Sage Green, Purple

20d Argon Ripstop Nylon: Purple

your-image.pngyour-image.pngyour-image.pngyour-image.pngyour-image.png

1.0 oz/sq. yard ripstop nylon shell material from Pertex and Argon and RSBTR. Sporting a robust durable water repellent (DWR) coating and exceptional softness leading to high lofting down sleeping bags and top level performing down jackets.

High quality all round fabric with a semi matte sheen. Some users report the black to be bordering on silver/grey.

USE: Recommended without hesitation for all products in the Nunatak line-up. These popular shell materials can be custom requested if not featured on the product page.




Shell Fabrics, Tough & Abrasion Resistant with added Weatherproofing

40d Epic by Nex-Tec: Orange


your-image.png

EPIC by Nextec ™: At 1.7 oz/sq. yard, this polyester microfiber features a durable water resistant silicone fiber encapsulation. The result is a breathable, highly water resistant, soft and pliable material that allows for excellent loft. The silicone encapsulation is inherent in the fabric, thus easily outlasting traditional water repellent coatings.

Micro ripstop grid. Matte finish, silent.

USE: A good weather protective option especially for garments and possibly quilts. For users requiring more than the usual moisture and abrasion resistance. Epic excels in damp climates, open ended tarp shelters, bushwhacking and general hard use. Note: A quilt with an EPIC shell will gain a fair bit of weight and bulk compared to the significantly lighter materials listed above. 



Ultralight Shell Options, with Enhanced Water Resistance:

7d Robic Ripstop Nylon: Charcoal Grey, Black, Olive and Bright Blue

your-image.pngyour-image.pngyour-image.pngyour-image.png

Extraordinarily light, this 7D fabric is treated with a microporous PU coating on the inside and a solid DWR application on the weather side. The ability to hold out moisture is very good with a HH of 1000mm, but not quite on par with the DryDome below. Breathability rate is adequate for down products. For a fabric with a square yard weight of well under an ounce, the Robic is relatively durable, in that department easily edging out the highly breathable Membrane shell.

Semi-gloss sheen, super micro ripstop pattern

USE: For applications where both UL principles AND weatherproofing come together as a definite need. 



 10d - 1.4 oz/yard DryDome Ripstop Nylon: Moroccan Blue

your-image.png

This could be regarded as a classic laminate, manufactured like other well known waterproof/breathables (WP/B): A base fabric with a Teflon style film layer laminated onto the inside face and a DWR on the outside. However, the unique quality of the DryDome, not seen in many other laminates, is the low square yard weight of 1.4 ounces, easily 25% less than the closest competitor. Choosing a 10D ripstop nylon base fabric, together with an upgraded WP/B film, makes this possible. It is decidedly a cutting edge high-tech material, but best not exposed to much abuse. This is the case with most super-ultralight fabrics, but here the lamination process further pre-stresses the fabric, So, user beware!

Semi-mattte, large ripstop pattern, a bit noisy when new.

USE: For conditions where the best protection against moisture intrusion in a relatively lightweight package is desired. 



LINER FABRICS, Calendered & Breathable:

20d Nylon Taffeta: Black

This high quality, silky smooth 20d nylon taffeta is specifically designed for the lining side of down gear. Comfortable against bare skin, low friction for entering and turning, silent and soft. Tough enough to deal with calloused feet. Light DWR coating and a matte look. Black only.

USE: Liner material of choice on projects with 1.0 oz or heavier shell material.

10d Nylon Taffeta: Black

An ultralight 10 denier taffeta (non ripstop) nylon that is breathable, calendered, and down proof. It offers excellent wind/water resistance, a soft hand, and tested down proofing in both lab and field use. At 10 denier and a finished weight of 0.67 oz/yd, our 10d taffeta is one of the thinnest/lightest taffeta nylon fabrics on the market today. 

USE: Liner for projects requiring the lightest weight and minimal stuffed bulk.  This is a specialist fabric, for users willing to adjust to a decline in durability and tear strength. Well suited to the the protected life of a quilt. The lightness translates to superior lofting ability of 900+ fill power down.



CAMO SHELL FABRICS
