Product description

This ultralight envelope sleeping bag is a compact, versatile sleep solution for campers, hikers, backpackers, and travellers who need reliable warmth without the bulk. Weighing just 1.5 lbs (0.68kg) and compressing into a 4-strap compression stuff sack measuring just 11.4 × 4.7 in (29 × 12 cm), it packs down small enough to slip into any backpack or travel bag with ease.

The outer shell is made from breathable nylon, with a soft T/C liner and 100% polyester fill rated for a comfort temperature of 59°F (15°C) and a limit temperature of 48°F (9°C) — ideal for spring, summer, and autumn use. The generous size of 74.8 × 29.5 in (190 × 75 cm) accommodates adults up to 5 ft 11 in (1.8 m) tall, and the double-sided zipper makes getting in and out easy from either side.

Unzipped fully, the sleeping bag opens flat as a blanket — handy for warmer nights or beach use. Two same-type bags can also be connected side by side to create a double sleeping bag for couples or anyone wanting extra space. Available in 2 colors: blue and orange.
