When you need to compress volume without significantly adding weight, Sea to Summit's Ultra-Sil Compression Sack is an excellent solution. Made from a water-resistant, bluesign® approved Ultra-Sil 30D nylon fabric with Non-PFC DWR this compression sack is far tougher than its weight would suggest. Ideal for use inside your pack or travel bag when you need to compress clothing or bulky soft items to allow space for other essentials or fun holiday items.

PRODUCT FEATURES:

• Side-release buckle compression straps for fast and easy access
• Compress soft contents down by as much as two thirds
• DIMENSIONS: 6.0 x 6.0 x 11.7 in | 15.2 x 15.2 x 29.6 cm
• WEIGHT: 1.9 oz | 53 g
• WATERPROOF? The fabric is waterproof enough for storage inside a pack, but the seams are not tape sealed, and the top does not utilize a roll-top closure. So - water resistant rather than waterproof
