Ultralight Warmth for Weight-Conscious Adventurers

The Big Agnes Zoom UL Insulated sets a new standard for ultralight backcountry sleep systems, delivering a high 4.3 R-Value in a package that weighs mere ounces. Designed for three-season use, this pad utilizes two layers of heat-reflective film to trap body heat and deflect the cold ground, ensuring you stay warm when temperatures dip. The 3.5-inch thickness provides a plush, stable cushion that smooths out even the rockiest terrain, making it an essential upgrade for any ounce-counting hiker or bikepacker.

Crafted with sustainability in mind, the Zoom UL features GRS-certified recycled nylon ripstop that is both lightweight and remarkably durable. The internal O-beam construction reduces weight while providing a stable, level sleeping surface that prevents the "bouncing" sensation often found in lighter pads. Setting up camp is effortless thanks to the included high-volume inflation sack, and the aviation-grade multi-function valve allows for micro-adjustments to find your perfect firmness and rapid deflation in the morning.
