The Peregrine Boreal 4 is an ultra-versatile, ultralight 4-person shelter designed for demanding backcountry missions. Built for adaptability, it excels as a group sleeping shelter, ski-touring cook tent, or a spacious ultralight basecamp solution. With its minimalist design and premium materials, the Boreal 4 delivers reliable weather protection without excess weight.
Constructed with 20D ripstop nylon with silicone/PU coating, water-resistant YKK zippers, and fully taped seams, the Boreal 4 is built to withstand harsh alpine and backcountry conditions. The 8-sided shape improves stability, simplifies setup, and maximizes usable interior space.
With 77 sq ft of floor space, the Boreal 4 comfortably shelters:
4 people with minimal gear, or
3 people with extensive gear
Pair it with optional half or full bathtub floor footprints (sold separately) to create a 4-season ultralight backpacking system.
A single included aluminum center pole keeps weight low while maintaining structure. Interior storage is provided via a gear hook at the apex, keeping essentials off the ground.
