Vortex™ Pump Sack

The stay-open collar is the detail that sold me—no more wrestling with a floppy opening while you try to seal it. That massive chamber held way more air than my old bag, so it only took a few scoops to top off my pad before bed.

First camp with it last weekend and filling my pad took maybe a dozen pumps instead of the usual minute of huffing. The massive chamber grabs air so fast, and the collar really does stay propped open while you shove it over the valve.

The stay-open collar is a game changer—no more wrestling with the bag while I try to fill it. I got my pad inflated in about a minute, which is way faster than my old method.
