Carrying a heavy, bulky sleeping bag to every camping trip is one of those compromises that adds weight and takes up half your pack. This ultralight cotton sleeping bag weighs approximately 760 g, compresses into a carry pouch small enough to hold in one hand, and unfolds into a full-length bag with enough room to move comfortably. Designed for spring and autumn conditions, it handles nights between 5°C and 15°C — the temperature range that covers most Canadian camping seasons.

Why It Stands Out

✓ Three-layer construction — outer 20D 380T nylon shell, 80 g/m² silk-like cotton filling, and a 240T polyester pongee inner lining that is soft against the skin.

✓ Water-repellent outer shell — the 20D nylon outer fabric resists light moisture and ground condensation.

✓ Two-way zipper — opens from the top or the bottom, allowing ventilation at the feet without fully unzipping.

✓ Spliceable design — two bags can be joined together using the left-zip and right-zip pairing system to create a double sleeping bag for two people.

✓ Fully opens into a quilt — unzip completely and the bag opens flat, usable as a quilt or sleeping mat liner.

✓ Compact storage — packs down to 31 × Ø13 cm, fitting easily into a backpack alongside other gear.

✓ Designed for adults up to 1.8 m — unfolds to 205 × 85 cm for a comfortable full-length fit.

Where It Fits Best

This sleeping bag is designed for three-season camping in spring and autumn conditions, where overnight temperatures stay between 5°C and 15°C. It works well in a tent on a camping pad, in a cabin or hostel bunk, or at a festival where you need a compact, packable sleep solution. Backpackers value its low weight and small packed size. The spliceable design makes it practical for couples or friends camping together who want the option of joining bags into a double. It also works as a travel blanket or quilt for journeys where a full duvet is not practical.

How the Construction Works

The outer shell is 20D 380T nylon — a thin, tightly woven fabric with a water-repellent finish that resists light moisture while keeping the bag lightweight. The inner lining is 240T polyester pongee, a smooth woven fabric with a soft, skin-friendly feel. Between these layers sits 80 g/m² of silk-like cotton filling which provides the insulation for the 5°C–15°C range. The two-way zipper runs the full length of one side and the foot box. The splicing system uses a left-zip or right-zip configuration — one left-zip bag zips to one right-zip bag along the full side seam to create a double bag.

Comparison Table

Packing and Setup

To pack, lay the sleeping bag flat and fold lengthwise into thirds, then roll tightly from the foot end toward the head. Insert into the included compression pouch and tighten the straps. To use, unroll and unzip fully or partially. For ventilation on warmer nights, unzip the foot end using the two-way zipper while keeping the upper body enclosed. To splice two bags together, ensure one is a left-zip and one is a right-zip, align the zippers along the full side seam, and zip together from bottom to top.

Cleaning and Care

Machine wash on a gentle cycle with mild detergent in cool water. Do not use bleach or fabric softener. Tumble dry on low heat or hang to air dry fully before storing. Store loosely rather than compressed for long-term storage, as sustained compression over time can reduce the loft of the filling.
