TerraLite – Ultralight Sleeping Bag for Side Sleepers

The TerraLite is an ultralight sleeping bag for side sleepers who need space to move without sacrificing warmth or weight. At just 1 lb 13 oz, it delivers premium performance for backpackers, overlanders, and comfort-focused campers.

This bag features a wide-cut design from shoulders to footbox. It gives side sleepers and restless movers room to shift without compressing insulation or feeling restricted. The 850+ fill power goose down lofts freely inside fully baffled construction, offering exceptional warmth-to-weight efficiency.

A breathable 12-denier ripstop nylon shell balances durability and airflow. It keeps moisture out while allowing internal humidity to escape. An insulated draft tube seals in warmth, helping you sleep through chilly nights in the backcountry.

Dual full-length #5 YKK zippers add versatile function. Open the bag from either side for ventilation or convert it into a flat comforter using the secondary zipper—perfect for warmer nights or quilt-style sleeping.

The TerraLite is a go-to choice for long-distance hikers, fastpackers, and weekend warriors who prioritize comfort, packability, and performance. It works well in three-season conditions and pairs easily with lightweight pads or bivy systems.

Use it in alpine zones, desert canyons, or forest camps. Wherever your trail leads, the TerraLite ensures you rest well and recover fully.

Proudly made in the USA, the TerraLite is one of Western Mountaineering’s best-selling bags for a reason. It’s light, warm, roomy, and ready to go wherever you do.
