GSI Outdoors Introduces the Travel Stack Line, a Modular System Built for Hot or Cold Meals on the Go

April 6, 2026

SPOKANE, Wash. (April 6, 2026) /OUTDOOR SPORTSWIRE/ – GSI Outdoors, a leader in innovative outdoor gear for over 40 years, today announced the launch of the Travel Stack Collection. This modular system marks a shift in outdoor insulation solutions, allowing hikers, campers and backpackers to carry a sleek container that ensures food and drink are at the desired temperature upon reaching the destination.

The beauty of the Travel Stack Collection lies in its versatility: the double-wall vacuum-insulated sleeve, the 2 Can Cooler, acts as a thermal housing for specialized container sets that stack perfectly inside. This is not a bulky soft-sided cooler, but a streamlined, rugged tool built to maintain hot or cold temperatures – 24+ hours of cold insulation or 10+ hours of heat in standard testing conditions – designed to slide effortlessly into a pack or be easily attached to the outside of a backpack for quick access and hands-free transport.

“At GSI, the ideas for our best gear usually start with a problem our team encounters while we’re actually out in the field,” said GSI Outdoors Director of Design Kurt Gauss. “This project originally started as a simple quest to keep two cans cold in the backcountry. But as we tested the vacuum insulation, we realized its potential was much broader. We decided to build an entire modular food system around that core insulation so you can keep meals hot or drinks cold on a long trek.”

Designed with true crossover appeal, the Travel Stack transitions seamlessly from a backpack on a multi-day trek to a golf bag on the back nine, and from a remote campsite to a pre-game tailgate. It is as much a tool for the weekend warrior as it is for the technical adventurer.
