Sierra Designs Cloud 20 Degree DriDown Sleeping Bag – Ultralight Zipperless, Long

Experience warmth and simplicity with the Sierra Designs Cloud 20 Degree DriDown Sleeping Bag

When you plan a backpacking trip or a weekend camp, weight and comfort sign the itinerary. The Cloud 20 merges ultralight construction with DriDown insulation to help maintain warmth while avoiding added bulk. The long size adds extra space for taller sleepers, making it a versatile choice for a range of outdoor nights.

Zipperless design for smoother nights

Skip the fiddly zipper and slide into a cocoon-like warmth. The zipperless concept reduces snag points and interior clutter, enabling a calmer, more effortless entry and exit after a long day on the trail.

Oversized comforter for home-like warmth

The top integrates an oversized comforter-style area that can wrap around your shoulders, delivering a roomy, cloud-like feel without compromising pack weight or performance.

Targeted warmth and adjustable airflow

An insulated shoulder pocket helps trap heat where you need it most, while a self-sealing foot vent provides quick control over airflow as conditions shift. The long length adds generous space for leg movement and comfort.

Practical design touches for real trips

A Sleeping Pad Sleeve keeps your pad aligned with the bag, reducing shifting on uneven terrain and boosting overall comfort and efficiency through the night.
