Sea to Summit eVent Compression Dry Sack XL (stseventcompdrysackxl)
The Sea to Summit eVent Compression Dry Sack XL (stseventcompdrysackxl) is the largest size in the valve-free compression dry bag line. Its base is made from air-permeable eVent® waterproof fabric, so air is forced out through the bottom as you tighten the four straps while water is blocked from getting back in. A 30 liter load packs down to roughly 10 liters — enough capacity for a winter sleeping bag, a bulky synthetic quilt or a full set of cold-weather layers.

Proper Use
- Any roll-top dry sack has to be closed correctly to keep water out. Fold the Hypalon® strip down first and make at least three rolls before clipping the buckle.
- Avoid contact with sharp objects and high-abrasion surfaces, which can compromise the waterproof fabric.
- As with every roll-top fabric dry sack, Sea to Summit recommends double-bagging sensitive electronics (one dry sack inside a second). For maximum protection use a waterproof hard case.
Frequently Asked Questions
How much does the Sea to Summit eVent Compression Dry Sack XL hold?
The Sea to Summit eVent Compression Dry Sack XL (stseventcompdrysackxl) measures 10.5" x 23" and holds up to 30 liters uncompressed. Tightening the four straps brings that down to roughly 10 liters, recovering about two-thirds of the space in your pack.
What is the difference between the L and XL Sea to Summit eVent Compression Dry Sack?
Size and capacity only. The Sea to Summit eVent Compression Dry Sack XL (stseventcompdrysackxl) is 10.5" x 23" and holds 30 liters at 7.4 oz, while the L size is 9" x 20" and holds 20 liters at 5.9 oz. Both use the same 100D nylon body, eVent® base and four-strap Hypalon® roll-top closure.
How does the valve-free compression on the Sea to Summit eVent Compression Dry Sack XL work?
There is no purge valve to clog or fail. The Sea to Summit eVent Compression Dry Sack XL (stseventcompdrysackxl) has an eVent® fabric base that is waterproof in one direction but permeable to air, so squeezing the sack pushes air out through the bottom while liquid water is blocked from entering.
Is the Sea to Summit eVent Compression Dry Sack XL fully waterproof?
The Sea to Summit eVent Compression Dry Sack XL (stseventcompdrysackxl) has tape-sealed waterproof seams and a non-wicking Hypalon® roll-top closure, so contents stay dry through rain, spray and an accidental dunk. Like all roll-top fabric dry sacks it is not intended for prolonged submersion.
How do you close the Sea to Summit eVent Compression Dry Sack XL properly?
Fold the Hypalon® strip at the mouth down first, then roll the top down at least three full turns before clipping the buckle. Three rolls is the minimum that creates a reliable seal on the Sea to Summit eVent Compression Dry Sack XL (stseventcompdrysackxl).
