We want to make extra-sure you realize that you've added a special order item to your cart. These items take a little longer to get to you because we have to order from the manufacturer first. The "Est. Ship Date" is the date we expect items to leave our warehouse... so add your chosen shipping speed to see when it will show up at your door.

Rated 4 out of 5 by from Waterproof pump sack Perfect piece of gear. Straps right on my handlebars for bike packing. Works like a dream to inflate the sleep pad. I look super cool with this piece of gear!!

Rated 5 out of 5 by from Valve incompatible Bonjour, J'ai acheté le Sac-pompe BlockerLite™ mais la valve de mon matelas thermarest n'est pas compatible (réf N50TRKR C 3111438) Est il possible de l'adapter ou de changer la valve, ou bien existe t il un autre modèle de sac de gonflage? Cordialement DB

Rated 4 out of 5 by from good addition This is an improvement over the included pump sac (not waterproof). It is water proof which allows double use as a stuff sac for my down sleeping quilt. The attachment point to the pad "blew off" a couple of times during the pumping process. I'm not sure how to make it more secure. It is a little fussy. I have the Xtherm max pad. At that price point I was disappointed that the included pump sac was not waterproof and that I had to spend even more to get a pump sac that can actually serve double duty. The quality of materials is very good and hopefully this will perform for a long time.

Rated 2 out of 5 by from Doesn't work as an inflation bag Bag slips off wing lock valve with just the slightest bit of movement. No way to inflate the pad with this bag as it will not stay connected to the valve. Disappointing, not recommended.

Rated 1 out of 5 by from Not compatible with older neoair thermarest. My bad for not looking at the compatible valves. My older thermorest neoair valve does not match this product. Will have to return. Double check which valve you have before buying.

Rated 5 out of 5 by from Works Well I bought this to go with an uberlite, works very well. No issues getting them to mate together (someone else mentioned trouble with the new wing valve, but mine worked perfectly. Maybe Thermarest has remedied this since then?), I was even able to connect them with gloves on, which is pretty nice if it's cold out. It takes about three goes to inflate an uberlite small. You can leave them connected while opening the other end and spreading the fabric to let more air in, doesn't need to be unattached and reattached each time. Would be nice if different sack dimensions were available. I use my sleeping bag inside a dry sack to help give structure and shape to my frameless pack. I was able to get this sack to work, but a narrower one would be more ideal. I also use my dry sack with an extra piece of clothing inside as a pillow, again this one works but a narrower one would be better. Something like 70% the width of this one would be great.

Rated 5 out of 5 by from Functions Well and Multipurpose Works great for storing bedding or other cold weather insulation. The material is strong and holds its shape after being compressed. Very useful.
