The REI Co-op Flash Sleeping Bag is a highly anticipated addition to the outdoor retailer’s lineup of ultralight backpacking gear. Designed with comfort, warmth, and convenience in mind, this sleeping bag promises to revolutionize your backcountry adventures. In this article, we’ll delve into the features, specs, and performance of the REI Co-op Flash Sleeping Bag to see if it lives up to its lofty claims.

Design and Materials

The Flash Sleeping Bag boasts a sleek and minimalist design that’s both functional and visually appealing. The 20D nylon ripstop fabric provides an excellent balance between durability and weight reduction, while the TPU-coated 10D nylon mesh lining ensures optimal breathability and moisture transfer. The bag’s shape is optimized for comfort, with a generous cutout in the footbox to prevent cold spots.

Insulation and Warmth

The Flash Sleeping Bag features REI’s proprietary Polarguard insulation, which provides an impressive warmth-to-weight ratio. This high-loft insulation traps warm air efficiently while minimizing weight gain. The bag’s 20°F (-7°C) temperature rating makes it suitable for spring and fall backpacking trips, as well as shorter winter excursions.

One of the standout features of the Flash Sleeping Bag is its incredibly compact size when packed. The stuff sack compresses down to a mere 4 inches (10 cm) in diameter, making it easy to stow away in a backpack or attach to a belt loop. With a total weight of just 1 pound 9 ounces (680g), this sleeping bag won’t weigh you down on long hikes.
