TREKOLOGY 30L Pump Sack Roll Top Compression Pump Bag for UL80v2 Sleeping Mats, Pump Sack for Camping Mats, Sleeping Pad, Sleeping Mattress, Inflatable Sleeping Mats

Quality material! Still good as new for me and it’s been a couple years. Things inside don’t get wet so it does the main job well, and it can be used as a pump sack for your sleeping mat.

Yes great very light very useful too washed great .

The Trekology 30l pump sac needs an adapter to fit my Thermarest Neo-Air Xtherm mat. It's connector is an exact fit for my knackered Thermarest Neoair’s pump sac connector valve, so it does not fit the Thermarest mat’s connection unless the rubber valve from the Xtherm’s pump sac is used as an adapter between the mat and the Trekology pump sac, which means you need the old sac to remove it from. Fit the removed Thermarest valve in the normal way to the Thermarest mat, then attach the Trekology pump sac to the valve (it’s a tight fit). Then it works good and fast, better than the original as long as you don’t squeeze too hard, then the adapter comes off. It looks made to last. Love it and well pleased.

Gets the UL80 air mat pumped up in 5-7 pumps. saves lots of time

If you bought the sleep mat, you need this. This makes inflating VERY easy. Its lightweight. You can store other things in it when moving. The quality is as good as the sleep mat. 100%, get this if you got the mat. This is well worth the extra money to make life easier.

A perfect (if not essential addition to the UL80 sleeping pad (also excellent).Far easier and far less damaging option to inflate your sleeping pad as it takes a few ‘bags full’ of air to almost completely inflate a sleep pad, but also prevents the moisture from your breath fromBuilding up in the pad itself.So small that you barely notice it, so simple that it is unlikely to fail.

Pumps up a UL80 nice and quick, takes about a half dozen to get it where I like it. And it's a reasonably generous dry sack, enough for me to get my bag, pad, and tent in.I'm a little suspicious that it isn't waterproof... Trekology say it's "water resistant". Frankly if it can't keep stuff dry it's a bit of a waste of space. BUT I don't backpack in super bad weather most of the time so I'm giving it the benefit of the doubt for now.

No need for batteries with this mattress inflation bag
