Sleeping pad pump sack adapters - Thermarest, Klymit, Sea to Summit, Big Agnes, Nemo, Exped

Like many people, I really dislike the Thermarest pump sacks. I think they’re a really lazy design from Thermarest and clearly they can do better because every other company has. The two best pump sacks I’e used are the Exped Schnozzel and Nemo Vortex. The Exped has the added advantage being able to be used as a pack liner.

There’s a few designs out there to adapt from the Schnozzel to Thermarest classic or wing lock valves, but I also wanted to be able to use these pump sacks with the variety of sleeping pads that I have. So I put together this library of adapters that go from either pump sack to all of the major sleeping pads on the market. These adapters also have a small loop that you can tie 2.5mm cord though to attach multiple adapters together or tether them to the pump sack (if you want to retain the use of the closure on the Schnozzel bag)

The adapters need to be printed from 3d printed from 95A TPU, a flexible material that is incredibly durable. They fit snuggly on the outlet of the pump sack and will not fall off, while remaining easily removable. They click securely onto the sleeping pad for inflation and do not pop off accidentally.

A quick note about the Themrarest classic (twist) valve version: It's okay, not great. The design itself is good, but because the classic valve doesn't incorporate a check valve, there's nothing preventing the pad from slowly deflating in between inflation cycles, or when removing the pump sack.

For people without a printer, or those who don’t want to deal with setting up a printer to print TPU, I also am going to try offering these for sale on my Website here: https://friesengear.com/product/sleeping-pad-adapters/ and my Etsy shop here:
