These compression straps work with both the Original Ocean Sleepwear Sleeping Bag and Volvo Ocean Race Sleeping Bag.
Simply fit the caps over either end of the uncompressed sleeping bag, squash down then tighten the straps to secure, length can be compressed by up to 40%.
For more compression, remove fold and pack the sleeping bag’s waterproof outershell separately, this will allow the fibre pile insulating layers to squash further.
Squash the sleeping bag and secure by tightening the staps.
