XCSS: Extreme Cold Sleep System

During my time at FELLFAB Limited, I was the project lead on the design of the Extreme Cold Sleep System (XCSS), working alongside fellow Industrial Designer, Alex Legault. Over the course of a year and a half, we developed dozens of sleeping bags. This work resulted in an innovative quick egress system, a patented no-snag ergonomic zipper, a clever cord management system, optimized fit, packaging, product manuals, label designs, multiple product videos, and ultimately a 2016 Red Dot Award for Product Design. 


The XCSS Extreme Cold Sleep System was designed to provide exceptional function and warmth in extreme environments. The patent pending LinZip technology has an ergonomic angled zipper to ease closing the bag, while the low-shear closure and unique dropped zipper allow the bag to be split open with little effort in an emergency. The innovative cord management system allows the hood and draft collar to be tightened from inside the bag, preventing heat loss and awkward pulling motions. Adjustment points are also mounted in place, making them easy to find in the dark. All hardware components are field replaceable for reliability during excursions.
