SummerLite – Ultralight Summer Sleeping Bag

The SummerLite is an ultralight summer sleeping bag designed for fast-moving backpackers, bikepackers, and thru-hikers chasing miles in warm weather. Weighing just 19 ounces, it delivers true ultralight performance without sacrificing comfort or warmth.

This fully baffled bag uses 850+ fill power goose down to maximize loft and warmth-to-weight efficiency. It keeps you warm on cool summer nights while staying compact in your pack. The 12-denier ripstop nylon shell is breathable and durable, offering protection without added bulk.

A full-length #5 YKK zipper allows for versatile ventilation. Open the bag fully on warmer nights or zip up tight when the temps drop. An insulated draft tube runs the length of the zipper to prevent heat loss and eliminate cold spots.

The SummerLite features a narrow mummy cut that improves thermal efficiency without feeling restrictive. It’s made for serious mileage, but comfortable enough for casual overnight trips.

Use it on long thru-hikes, high-elevation summer loops, or fastpacking routes where every ounce matters. It’s ideal for backpackers who cut weight but won’t compromise sleep.

Whether you’re climbing into your tent at 10,000 feet or cowboy camping under the stars, the SummerLite ensures you’ll stay warm and rest well.

Proudly made in the USA, this bag blends performance, simplicity, and comfort in one ultralight package. For those who demand efficiency and reliable warmth from their gear, the SummerLite is the go-to summer solution.
