Big Agnes Zoom UL Insulated Regular

The Big Agnes Zoom UL Insulated Regular is an ultralight airbed built to keep backpackers comfortable and insulated from the cold ground. It’s designed for those who want a minimalist sleep system without sacrificing warmth or durability.

Constructed with a double ripstop nylon top and a two-layer ultralight heat reflective film, this pad offers a sturdy yet lightweight feel. At 9 cm thick when inflated, it provides ample cushioning over rocks and roots, while its 10 x 20 cm packed size slips easily into your pack. These features combine to deliver a snug night’s rest and free up precious space for other essentials.

With an R-value of 4.3, this pad offers strong thermal resistance, meaning it effectively slows heat loss to the ground and helps maintain body warmth in cooler conditions. The R-value is a measure of how well a material insulates—at 4.3, this pad is well suited for three-season adventures and colder nights when extra insulation matters.
