Sea To Summit UltraSil Compression Sack 13L

The Sea To Summit UltraSil Compression Sack 13L is a lightweight, highly compressible storage solution designed for backpackers, campers, and travelers who need to minimize pack volume. Made from ultra-light 30D Ultra-Sil Cordura Nylon, this sack reduces the volume of your gear by up to 66%, making it ideal for bulky items like sleeping bags, clothing, or camping equipment.

Advantages

Weighing only a few grams, the UltraSil Compression Sack offers exceptional weight savings without sacrificing durability. The silicone-impregnated fabric provides water resistance, while the seamless base and bar-tacked stress points ensure long-lasting performance. Four nylon webbing compression straps with Duraflex buckles allow for even, secure compression, and the drawstring closure with cord lock keeps contents safely inside.
