About the Sierra Designs Cloud 800F 20 Long

What is the Sierra Designs Cloud 800F 20 Long good for?

The Cloud 800 20° Sleeping Bag is ideal for 3-season, cold-weather camping, trekking, and alpine trips. It’s designed for fast-moving outdoor adventurers who want lightweight gear that doesn’t sacrifice comfort or warmth.

How will some of the key features of the Sierra Designs Cloud 800F 20 Long enhance my experience?

This bag is built around an ultralight 15D nylon ripstop shell and liner to keep the pack weight low. It’s insulated with 800 fill power DriDown, which stays warm even when damp and is responsibly sourced and PFC-free. Instead of a traditional bottom insulation layer, it features a sleeping pad sleeve to save weight and keep your pad in place. A standout feature is Sierra Designs’ patented zipperless construction, which uses an oversized, integrated comforter and a crescent-shaped opening to offer unrestricted movement while sealing out drafts. It also includes an insulated shoulder pocket and an adjustable hood for added warmth. For warmer conditions, a self-sealing foot vent allows for easy ventilation, and the comforter can be folded out of the way.
