This is the first of four articles sponsored by Arc’teryx LEAF to educate readers on softshell fabrics used in their garments. In this article we will cover Tweave, a product of Gehring Textiles.
Specifically, Arc’teryx LEAF currently uses two types of Tweave in their clothing and equipment; Tweave Durastretch (520E) and its lighter weight counterpart Durastretch LT (536N). The Sphinx Halfshell you see here actually incorporates both fabrics. Both weights of Tweave boast Durable Water Repellant coating as well as a material content of 91% nylon and 9% Spandex. Arc’teryx offers products manufactured from Tweave in Crocodile, Black, Coyote, and Multicam as well as the new Wolf color.
Arc’teryx actually worked with Tweave to develop the Durastretch fabric in the early 2000s for outdoor alpine climbing, trekking and backcountry ski apparel. But, after a few seasons it became too pricey for those markets. With the advent of LEAF, Arc’teryx revived use of the fabric for their new customer base whose main emphasis is on performance. Tweave is recognized worldwide as the most durable stretch woven available.
Tweave combines several properties to protect you from the elements. It is a plain weave four-way stretch that has superior durability and abrasion resistance. The fabric is very tightly woven and you will notice this on windy days. Additionally, its smooth face sheds snow and DWR finish repels moisture. The construction of the Durastretch fabrics, using covered yarn technology, keeps the more vulnerable spandex yarns protected from the elements by wrapping them inside the nylon, unlike many other fabric which feature exposed spandex without a sheath. Tweave chose nylon over polyester because of its superior abrasion properties and the yarns are extremely compacted and tight, yielding a very abrasion-resistant surface. All of this is topped off with special finishing techniques that still allow ample stretch for comfort and freedom of movement.
