Sea To Summit Compression Sack 20 L Olive

When every gram counts and space is at a premium, the Sea To Summit Compression Sack 20 L Olive steps in. Unlike ordinary stuff sacks that simply hold gear, this compression sack actively shrinks bulky items like sleeping bags, down jackets, and clothing into a compact, manageable package. Its 20-liter capacity is generous enough for a full sleep system, yet the four radial compression straps cinch everything down to a fraction of the original volume. The olive colour blends naturally into outdoor environments, and the ultra-light 30D Ultra-Sil fabric keeps the total weight to just 104 grams—barely noticeable in your pack.

Highlights

• 20-liter capacity ideal for sleeping bags, insulation layers, or a weekend clothing kit
• Ultra-Sil 30D siliconized CORDURA® nylon fabric: extremely light, strong, and water-resistant
• Four radial compression straps with field-repairable 2-pin buckles for reliable, even compression
• Drawstring closure with cord lock and lid keeps contents secure and protected from dust and moisture
• Bar-tacked stress points and reinforced stitching enhance durability in high-tension areas
• Compresses from 23 x 50 cm down to approximately 23 x 17 cm, saving up to 66% of pack space

In daily use

Pack your sleeping bag into the sack, pull the drawstring tight, and then systematically tighten the four straps. The cylindrical shape fits neatly into the bottom of a backpack or into a kayak hatch. The siliconized fabric slides easily against other gear, reducing friction and making packing and unpacking smoother. When you need to find something quickly, the bright interior (if applicable) or the simple lid design allows fast access. The water-resistant coating sheds light rain and splash, keeping contents dry in most conditions. For longer trips, the sack doubles as a pillow when stuffed with soft clothing—just loosen the straps slightly for comfort.
