Proprietary waterproof laminate developed specifically for Spyder by Toray Fabric. It's hydrophobic microporous breathable construction is best in class. The addition of 4-way stretch makes this laminate superior to others.

3M™ Thinsulate™

Thin yet protective, the trusted warmth of 3M™ Thinsulate™ Insulation is your low-profile answer to cold. The microfibers that comprise 3M™ Thinsulate™ Insulation efficiently trap insulating air, reflect radiant body heat, and deliver warmth that is two times greater than down and other polyester insulations, when equal thicknesses are compared.


When the powder is deep you need all the dry you can get. Enter Spylon™ durable water repellent (DWR) finish, which retains 80% of waterproofness after 20 washings, and guards against water- and oil-based stains.
