Patagonia Releases a Full Down Sleeping Bag

Patagonia Sleeping Bag

Forty five years ago, Yvon Chounaird built himself a sleeping bag — a simple mummy style bag with overstuffed channels and center-front zipper that let him tie in at belays, cook at bivies, and move around without the bag twisting. Patagonia took that bag and updated it using the latest materials — the result is the new 850 Down Sleeping Bag.

As sleeping bags are such an essential part of any alpine kit, it’s amazing Patagonia hasn’t released a full sleeping bag before now (last year they released the elephant foot). The brand is no stranger to down insulation, however, with their range of puffy jackets the most popular in the world.

The three-season Down Sleeping Bag comes in two models — 19°F / -7°C ($499, 912 grams) and 30°F / -1°C ($399, 734 grams), both of which are EN tested and rated. Both bags feature a custom, differentially cut foot-box pattern that eliminates dead space and bulk, maximizes warmth, and affords ample room for movement. Each sleeping bag contains only 850-fill-power Traceable Down, traced from farm to factory to help ensure the birds are not force-fed or live-plucked.

The shell fabric is an ultralight 100% nylon ripstop Pertex Quantum fabric, which features 15-denier Y-shaped filament technology that allows maximum down loft, provides superior durability, and enhances the performance of the DWR (durable water repellent) finish. The liner is made from the same fabric as Patagonia’s Houdini styles: a durable, but lightweight 15-denier 100% nylon ripstop that dries quickly and feels good next-to-skin.

Unique to the 19°F bag is the comprehensive differential baffle construction, which is a method of designing a sleeping bag with no sewn-through areas and a smaller liner circumference to the larger shell, to help ensure the down stays lofted, and cold spots are eliminated. The 30°F bag features stitch-through construction—a simple and lightweight solution that is perfect for warmer weather or light-and-fast, minimalist needs.

Available now, the 850 Down Sleeping Bags come in three sizes for each model — short, regular, and long.
