Sea to Summit Ultra-Sil Compression Sack
When you need to compress volume without significantly adding weight, the Sea to Summit Ultra-Sil Compression Sack is an excellent solution. Made from a 30D diamond rip-stop siliconized CORDURA® fabric 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.
Please note that these dry sacks are made by Sea to Summit and are imported (not made in NZ).
Extra long straps for even compression, allowing you to fill the sack to capacity.
Tough, lightweight & water resistant
30D Diamond Ripstop Siliconized CORDURA® provides strength and a slippery finish for easy packing. 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.
Reinforced with bartacks
Bartacks at stress points for added strength.
Which dry bag is right for me?
This depends a lot on what you intend to use the dry bag for. The Sea to Summit Big River Dry Bag is well suited as an all round versatile dry bag for particularly wet conditions, overland expeditions or when your adventure includes water/paddle sports. It will fit comfortably in our ROBO-KIWI harnesses, but is shorter, wider and heavier for its volume compared with ROBO-KIWI dry bags. For the best bikepacking-specific dry bag, we recommend using ROBO-KIWI double-ended dry bags as they have been specifically designed for fitting on bike handlebars.
For temporary extra storage on longer multi-day rides, brevets or bikepacking races where you need to periodically resupply or a lightweight summit day, we recommend the extremely compact and ultralight Sea to Summit Ultra-Sil Nano Day Pack.
Worth their weight and cost?
Once you have experienced modular packing with ultralight compression sack you’ll wonder how you ever lived without them.
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.
