No more huffing and puffing to inflate your sleeping pad. This is especially helpful for high elevation camping. Flick it open to capture some air, fold it over and hook up the connection to the sleeping pad and youre done. Easy as that
Unfortunately I can't give this a "full review" because I didn't realize it would not work with my REI AirRail pad. We bought two of these for our Peru trek. The sack kept my down bag safe and dry. It would be awesome if Sea to Summit made this in a "universal" design with adapters for various valve sizes.
I bought this bag B/C it was comparable with my two REI FLASH Insulated air mattresses (3 season and All Season). 1.This bag works great as a quick inflator, keeping heat-robbing breath moisture and bacteria out of the mattresses. 2. Also it is a good dry bag for clothing, saving the weight of separate dry bags. * I put a light polyester T-shirt over the head of the mattress for "facial comfort" in 3 season use.
I'll admit that I've been slow to join the pump dry sack bandwagon. But, after reading up on bacterial growth in sleeping pads from people blowing them up manually, I decided it was time. I have to say, this is a nice change. The bag has replaced another stuff sack so there is no additional weight in my pack but this sack has multiple purposes. Brilliant!
Makes inflating my Sea to Summit Comfort Plus pad nearly effortless. If you have a 2018 version of the Sea to Summit pad line, their stuff sacks are already pump sacks so this is unnecessary. But for my needs, and the dual functionality that this can keep my bag nice and dry, this is perfect!
Bought this stuff sack since we were able to use it as a pump for our REI sleeping pads. What a great combination! Not only do you end up with a tough little stuff sack, but about the lightest choice for an air pump you can find! Dual purpose!
It inflates my StS ultralight pad in about 2.5 bagfuls. And it helps me compress my 650 down fill bag to a smaller size. Helps me fit my sleeping bag into my ultralight pack. Thin and light material but tough.
It is easy and fun to set up my SeaToSummit mattress with this bag. No more hard blows. In addition, this bag can be used as dry sac for my sleeping bag.
At the end of a 80 mile day of touring, what a joy to have a few quick puffs on this bag to inflate my air mattress. No condensation, no laboring.
Super easy to use and save a ton of time, the best part is one doesn’t get light headed trying to blow it up the old fashion easy.
Pump sack did a great job and was easy to use... Easily packs away
