We are pleased to offer some of the most technical shells, used by top brands. 

From the fabulous Polartec® NeoShell®, which is twice as water repellent and breathable than Gore-tex®, to HyVent DT used by companies such as North Face, as well as other technical shells being used by top brands, we have a great selection to help you make the most durable, lightweight, functional outerwear.

Most of these are almost impossible to find elsewhere. A few are experimental samples, so yardage is limited.  Browse through each category and decide what the best choice is for your special project. 

Whether you're looking for a lightweight shell, or an outer fabric to use with the fabulous Polartec® Alpha®, you're on the right page.


What's the point of waterproof if you are always soaked with sweat?

Polartec® NeoShell® is an engineering breakthrough for waterproof breathable fabric technologies. Dynamic air exchange at the surface provides the unrivaled ability to stop water and wind permeation without restricting the release of excess body heat and moisture vapor. This highly aerobic air permeability provides the unique benefit to function as a durable protective shell with advanced wicking capabilities to keep moisture vapor moving away from your core.

Releasing excess heat directly through the fabric membrane reduces the need to manually adjust gear during activity. Shedding entire layers or relying on pit-zips to dump heat often leads to overexposure that can be avoided altogether through enhanced breathability. This allows Polartec® NeoShell® to excel in both inclement weather and calmer conditions.  We offer several colors, each roll looks similar to the next however they may differ slightly in weight or composition. For example, the Navy Neoshell is approx. 9.5 ounces per linear yard (269 grams)  and is just under 56" wide. 


Available In: Charcoal, Grey, Cream, Coyote Brown, Bright Yellow, Digital Camo, Navy, Peacock Blue (Has Power Dry Backing) SOLD OUT, Hi-Vis Orange, Black (grey back), Black (Charcoal back) SOLD OUT, and Black Twill     





Polartec® describes this style as a 'warm shell' with a brushed tricot backing to give it a fuzzy feel as opposed to a regular tricot backing.  It does not have any stretch.





Polartec® Power Shield Pro® style 6617

This style is so crazy-light you won't believe it. A linear yard weighed approx 3 ounces (75 gram!)  It's 54" wide. It was intended to be a face fabric utilizing Polartec® Alpha Direct® insulation, but we've used it alone to make a super-light travel jacket that packed up to almost nothing!

NeoShell is not any one fabric, rather a family of fabrics that share the same technical qualities. If you are looking for a heavier NeoShell, we offer one in both Spring weight (backing is Power Dry) as well as High Loft.  For those styles, visit our Soft Shell page


Technical shells from other quality brands: 

Keep in mind that while most of these can be worn alone as a shell, they can also be used as a main face fabric and insulated with Polartec® Alpha®


A very strong and lightweight technical fabric that is water repellent and extremely wind resistant.  The feel is very soft and feels great against your skin.  It's an ideal fabric for making super lightweight/packable jackets or vests.

Fabric swatches of HyVent DT shell fabric in soft blue, gold and navy

HyVent DT

This ultralight waterproof technology ensures lightweight, packable protection that is ideal for outdoor adventures where you need maximum protection whilst taking up minimal pack space. This innovative fabric is created by applying a polyurethane coating with a DT print matrix which acts as a dry touch half layer coating, which adds greater durability and comfort by separating the PU coating from the surface of the skin and eliminating the need for a liner. Even so, you can beef it up with Polartec® Alpha® insulation to make a fabulous, warmer jacket.  HyVent is extremely water and wind repellent.

First Quality-Available in: Gold, Navy $20/yd

Second Quality-Available in: Soft Blue $10/yd.  The flaw is a variation in the fabric that runs lengthwise throughout the roll.  One stripe is fairly obvious, others are much fainter.  This fabric is perfect for making a muslin or for a backpack cover, stuff sacks, panier covers to name a few uses!

Example of a jacket that is made with similar technology:

Aluminum Back Shell

This fabric is rumored to come from Nike. It is 56" wide, and features an aluminum finish on the back to reflect body heat. Very water repellent and breathable. Lovely shell fabric. 

Royal Blue


Fabric swatch for shell fabric in black


We're not sure of the origin of this lovely shell, in fact we made up the name! Very soft but durable, and highly water repellent and breathable. 58" wide, weighs only 4.4 ounces (125 grams) per linear yard!  Although it makes a lovely shell for outerwear, we can imagine a lot of great uses, such as making a bivy and other outdoor gear for ultralight backpacking.
