Sea To Summit UltraSil -puristuspussi 35L

The Sea To Summit UltraSil Compression Sack 35L is an ultralight and durable compression sack designed for backpackers, campers, and travelers who need to minimize pack volume. Made from 30D siliconized CORDURA® nylon, this sack is water-resistant and incredibly strong for its weight. The compression system uses four Hypalon reinforced straps to reduce gear volume by up to two-thirds, making it ideal for bulky items like sleeping bags and clothing.

Advantages

Ultra-lightweight at only 108 grams, the UltraSil Compression Sack offers exceptional strength-to-weight ratio. The siliconized fabric provides water resistance, while the Hypalon reinforcements at stress points ensure long-lasting durability. Field-repairable buckles and double-stitched seams add to the reliability. The drawstring top with lid keeps contents secure and protected.
