Ultralight Mummy Sleeping Bag

The Altos-S 0F is a mummy-style sleeping bag built for adults who camp, hike or backpack in winter conditions. Its polyester shell and liner enclose a synthetic insulation fill that resists moisture while keeping weight low. The bag compresses into the included stuff sack so it fits easily in a pack.

0 °F Rating and Twin Capacity

Rated to 0 degrees Fahrenheit, the bag provides warmth for cold-weather nights and the twin size accommodates two people when needed. The 84-inch length suits users up to that height, while the 32-inch width gives shoulder and leg room with a built-out footbox for extra foot space. Thermal resistance is 2.5 watts per meter per degree Celsius, so heat retention drops off in temperatures well below the rating.

Lightweight Pack Weight and Care

At 3.5 pounds the bag adds minimal load to a backpack and the compression sack with heavy-duty straps makes packing quick without rolling. The polyester ripstop shell and nylon fabric resist water and abrasion during normal use. Hand-wash only when cleaning is required.

Questions about this item

Will the 84-inch length and 32-inch width fit alongside my existing twin-size sleeping pad?

The bag measures 84 inches long by 32 inches wide, matching a standard twin footprint so it lays flat on most single pads without overhang.

How can I verify the 0 °F rating is performing after I set it up?

In calm conditions you should feel consistent warmth down to the rated 0 °F; cold spots near the zipper or footbox indicate the down fill has not fully lofted.

Does the package include the compression sack or do I buy it separately?

The box contains the sleeping bag and a compression sack with heavy-duty straps, so nothing extra is needed for packing.
