    Size: Extra Large Verified Purchase
    Wasn't sure at first, because it seems to quite flimsy on first inspection. However now it has been used it seems to in fact robust and well made. Only time will tell I guess. It seems to be well waterproof, but I have not tested thoroughly enough for this to be guaranteed. Certainly it is water repellent. Again time will tell. :)
    As it is not listed elsewhere, that I saw the sizes are as follows:
    XL : 27 cm x 58 cm; 210g; 30 litre max; 10 litre min.
    L : 23 cm x 50 cm; 168g; 20 litre max; 6.7 litre min.
    M : 20 cm x 46 cm; 148g; 14 litre max; 4.5 litre min.
    S :18 cm x 40 cm; 129g; 10 litre max; 3.3 litre min.
    XS : 15 cm x 35 cm; 107g; 6 litre max; 2 litre min.

    These are their figures, not mine. :)

    As my husband and I are daft enough to do camping weekends on our motorcycles during the winter months, warm sleeping bags are obviously important!! I recently purchased a bag designed to appeal to Carp fishermen..its a lovely warm and roomy bag which unfortunately rolled up to the size of a small Dinghy!! I purchased the Sea to summit XL compression dry sack and am happy to report that it compressed my Sleeping bag down to a much more managable size and has the added advantage of keeping it dry too (unlike the bag provided with it..)This has made packing it onto the bike much easier.. and will save me wrapping my gear in numerous bin bags which invariably disintergrate and let water in at speed... I'll let you know how it performs after a couple of outtings but I can certainly envisage purchasing more for my clothing etc...

    Its now done several outings in all weathers and performed brilliantly... It is a very good piece of kit..Recommended!!

    Size: Extra Large
    This bag is great, light weight, light colour so you can find items in the depths of it, well constructed and a great design. When stuffed full of "stuff" and squeezed down, it does a top job of squashing it all down thus saving precious space in your bag (/canoe/car/whatever). The eVENT construction allows the air out and stops the water getting in, perfect. When dunked in a sink full of water and held under by a breeze block (you have to test these things..) it held off all moisture for the half hour we had it under. Top product!

    Size: Medium Verified Purchase
    These little compression dry bags are a great upgrade to your existing compression sack with down or synthetic insulation gear.
    They can compress a sleeping bag much further than the usual manufacturer bag in most cases, while also providing some water protection. Usually the biggest challenge of drybagging a sleeping bag is getting the air out. With these eVent bags the air is expelled as you compress with the straps.

    I own the medium for a three season Alpkit Skyehigh 800, the Large for a skyehigh 1000 and the small which stores an Alpkit Filo down jacket and a pair of Montane Prism pants.

    All three provide superior compression to the manufacturer bag, with great water protection

    Size: Extra Small
    This product fulfil's its main criteria: It reliably keeps your goods dry (essential when its holding your down sleeping bag or jacket) and delivers a consistent level of compression to make those litres of your backpack go as far as possible. It offers a great improvement over trying to compress your sleeping bag into a regular dry bag- as you can stuff it in with minimum effort then let the straps do the work. The only real downside I see to this is it is not the lightest solution out there- but if you're not worried about shaving off every last gram then this will do the job just fine.

    Size: Large Verified Purchase
    Excellent compression sacks. The large is has enough room to get my Hilleberg Soulo tent in [minus the poles], my Marmot Hydrogen down bag & a NeoAir Trekker. It compresses all 3 down to a third of their size & the waterproof test? While I was playing with it to see what I could get in there, we had a Mountain Rescue shout & I raced off, leaving the compression sack in the back garden with my down sleeping bag inside. The nice sunny day that it was, turned into a monsoon in the late afternoon & on return 6 hours later I realized what I had done, brought it inside, pulled the sleeping bag out - bone dry! It's the best endorsement I can give at the moment, but spending a little more on quality equipment is the best way to spend less, replacing quality equipment, subjected to failure because of poor quality equipment.

    100% waterproof, extremely rugged. Note: the XL is way too big for a standard sleeping bag, you could easily get two bags in there and have space for more. The straps make compressing the load easy and they're easily undone too.

    This is one of the best compression sacks out there - the key is not only in being waterproof but in also allowing air to escape the bag you really can compress it down in a way that is just impossible with say exped rollsacks. For things like compressing and protecting a sleeping bag/tent this is crucial, particularly if you're backpacking, which i was recently and this kept my 3 man tent compressed to the size of less than a football. VVV impressive. Sidenote is that construction is excellent, straps are hardwearing and seams are double stitched and taped. OVerall a great buy for backpackers/campers/outdoorsy types :-)
