    Purchase Exped VentAir Compression Bag

    The Exped VentAir Compression bag uses a special waterproof, air permeable fabric to produce a bag from which air can easily be expelled. This allows you to roll the dry bag closed and then cinch down the compression straps to give the absolute minimum pack size. This makes the VentAir ideal for holding clothing, sleeping bags and other bulky, soft items. As the VentAir features four straps it allows for 360° compression ensuring the contents are pulled into a regular shape for easy packing.

    Exped VentAir Compression Bag Review

    I agree with much of what Stephen, Bristol said about the pros and cons, although the cons don't seem to matter as much to me as they do to him.

    A couple of other points I'd like to mention:

    1. The Exped bags have their breathable panel around the sides, whereas the S2S ones have theirs in one end. In order for air to escape from the inside, it has to get to the breathable part of the bag. How easily/quickly this can happen depends on what's in the bag - if it's down or fleece the air flow will equalise quickly, but if it's gore-tex or some such it won't. The exped design is less vulnerable to this becoming a problem. I have had to re-pack one of the S2S-style ones before now, in order to release an air bubble which stubbornly refused to work its way down to the end with the permeable membrane in it.

    2. The biggest bag to be had is in the Exped range (provided it comes sized to spec, that is). Since cylindrical bags don't tesselate, packing more, smaller bags is usually less space-efficient than packing fewer, larger ones. This could matter, depending on the dimensions of your rucksack or holdall.

    I bought both the Exped and Sea to Summit (S-S) compression dry bags in several sizes for an open boat trip to a Scottish island, all to be contained in larger bags.Both operate on the same principle (compression of a cylindrical container with a roll-top seal by 4 external straps and air vented through a semi-permeable membrane).The key functional difference is that the traction points for the compression straps on the Exped bags are attached to the side walls of the cylinder (so throwing some of the tension onto the roll-top water seal) whereas the Sea-to Summit bags have a floating external cap to which one end of the compression straps attach, and this sits over the roll-top seal, so protecting it from abrasion and reducing strain on it.

    The S-S bags were presented to me as 'more of a fiddle' (to slide the external cap into place) but in fact the design is mechanically much more sound and moreover the compressed bag is then smoother, with less likelihood of snagging on other objects than is Exped's exposed roll-top.And in practice, I didn't find the extra few seconds needed to locate the S-S cap properly to be a fiddle at all.The vent fabrics worked similarly and the impervious fabrics, roll-top seals and clips were also very similar for both makes.That some of the compression strain is taken by the roll-top seal on the Exped bags is enough of a disadvantage for me to regard it a design flaw - it is bound to fail sooner because of this.

    One other major disadvantage for the small Exped bag was that it was smaller than advertised (diameter 1cm smaller and length 2cm shorter) and this made a critical difference to its capacity to hold our carefully measured sleeping bags.I can't tell whether this was a systematic fault or poor quality control; either way it is poor - and a MAJOR irritation for a web purchaser.

    The two final and minor disadvantages for the Exped bags are the smaller range of sizes offered and the higher prices charged (compared to S-S).

    The Exped bags had one small advantage over S-S: less packaging was used and it was made of cardboard rather than plastic.Exped deserve praise for this.

    Perfect with the rucksack part of my old Berghaus Cubic 6+15 to keep everything dry on my cycle commute.

    Best laundry bag ever.Dirty clothes take up room.Wet and/or dirty clothes make other clothes/gear wet and/or dirty.I bought this to keep my laundry away from my clean clothes and gear and in a compressed way.It compresses clothes down as small as it can go with the ventair system and it is waterproof inside and out.Highly recommended.

    The medium size VentAir [just] accepts my 'Big Agnes Encampment' 15F-rated long synthetic bag - a really big bag. Compresses it easily to around 2/3 of original height - while keeping the same diameter - allowing an easy stow across the base of my 60l Exped pack. Solidly made & easy to use, with no semi-detachable bits to lose or tangle. Reliably waterproof - I've bought a second one.

    This is essentially a standard compression stuff sack with a band of yellow material near the bottom which is water tight but lets air through. This means that when you pull the compression straps the air which would normally be trapped at the bottom can escape giving you a smaller size. The other material used is very similar the the standard exped bags. Other compression bags I have used have a draw string inside. This one does not have one but that did not seem to be a problem. Size wise, I got the medium and it just fits my Rab expedition 1200 - which is a huge bag. It managed to get this bag significantly smaller than the other compression bags. I like it a lot.
