We tend to favor versatile gear, which is why we love the BlockerLite Pump Sack for our backpacking and camping adventures. Along with functioning as a lightning-fast pump sack for our sleeping pad at camp, it also functions as a waterproof bag for our gear when we hit the trail.

Pumpsack does not work anymore.

It seems that the fabric is not airtight anymore and it is not possible to get any air into the mattres. Is it possible to get the sack airtight again. How can i do this?

Will Not Stay Attached No Matter What I Try

This bag will just not stay attached to my sleeping matt, at most you get 2 pumps out of it and it falls off, the attachment itself is extreemly loose and ill fitting and just slips on and off with no effort at all, the pump bag that came with my matt works great it that clicks on with a audible click and has a secure grip on my matt and easily inflates it. I only bought this pump sack so i could use it as a dry bag to protect my matt and obviously to also inflate it and to remove the need to carry a separate pump sack. thankfully i tested this pump sack indoors and discovered it was useless rather than finding out when i was off camping

Therm-a-Rest BlockerLite Pump Sack Won’t Stay Connected To My Matt

I can’t even get one inflation into my Therm-a-Rest NeoAir XTherm with this sack popping off, the connection is extremely loose and no matter what it will not stay connected to my matt unlike the one that came with my matt which works fine, I’ve not even used my matt outdoors yet either, I only inflated it at home to test it which I’m glad i did.

Unfortunately, the sack does not

Unfortunately, the sack does not stay attached to my sleeping pad, unlike a friends sack I used, so it does not work.

Bad design AND bad quality EQUALS Ultra bad product.

Design issues: 1. The mount is not firm enough and will frequently disconnect from your sleeping pad. 2. The mount is made of hard plastic and only glued to one side of a soft sack. This is bound to fail sooner or later. Quality: It only took one use for parts of the glue/seal to fail between the pump sack and the mount. This is not only because of bad design, but also because the glue in parts of the seal never had bounded to the mount. It's a nice idea ... and you can probably keep it alive be frequent repairs.

I am using this to

I am using this to inflate my Neo XTherm. Unfortunately it disconnects from the wing nut inflation valve way to easily. I have to use one hand to hold it onto the wing nut valve.

Connection doesn't fit

The connection on the bag does not fit and is far too loose. When inflating, it slips off the valve. The product is not suitable for inflating the mat. The bag's thin material may not provide adequate protection for equipment. The product is completely overpriced.

Sack tore within a month

Sack tore within a month from trying to use as dry bag. Went back to my electric pump and separate dry sack.

Great pack liner.

Great pack liner. Lighter than the MSR claimed weight & big enough for summer clothing, sleeping bag & mattress. Nice insurance to keep gear dry & quickly inflates the pads. Looks like it will hold up well. I just wish the stuffsacks came in more colours.
