TREKOLOGY30L Pump Sack Roll Top Compression Pump Bag for UL80v2 Sleeping Mats, Pump Sack for Camping Mats, Sleeping Pad, Sleeping Mattress, Inflatable Sleeping Mats

So simple and works a treat - inflating a mattress has never been so easy and quiet!The mattress is well made, comfortable and easy to use.The one negative thing is that the mattress ‘rustles’, this maybe simply because it is new.

This makes blowing up the mat really quick and easy, I wish I’d bought it sooner

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.

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.

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.

Good pump sack, would like to see this included with the mat though like with most other brands

Seems decent as a pump sack as it removes moisture introduced via breath but as a dry bag, it’s not the best I’ve used

Brilliant
