These ultralight compression sacks are made from high-tenacity 30D Cordura ripstop nylon for excellent strength and durability with minimal weight. The fabric features a siliconised outer coating and a PU-coated interior, offering water resistance suitable for typical outdoor use (please note: seams are not taped, so these are not fully waterproof).Ideal for reducing the bulk of sleeping bags or clothing, each sack uses four compression straps with lightweight Kross buckles to halve the packed volume. A protective top cover helps apply even compression while shielding the contents. Each sack includes a drawcord top closure with an anti-snag system for smooth and reliable access. The translucent fabric also helps you easily identify the contents inside. These compression sacks are available in three sizes to suit your needs. The 5-litre version measures approximately 28.5cm high and 15.5cm in diameter and weighs just 65g. The 10-litre version measures around 35.5cm high and 18cm in diameter with a weight of 80g. The 15-litre option offers even more space, measuring 41.5cm high and 22cm in diameter, and weighs just 90g. Designed to save space, stay light, and keep you organised-these sacks are perfect for any expedition or outdoor adventure.
