Looks impressive on weight. Thanks. A regular old style tube doesn't weigh much more, maybe a pound or two for less than $100. This one appears to have more lift, and better valve design.
I picked up an Outcast Trinity when a sporting goods store closed down about 5 years ago. Pricey at full price though:
It packs down about the same. The big advantage is you only really are down in the water below your knees. It weights about 6 lbs (says 7 lbs on the website now).
If price is no object, this one looks is light and like the Trinity, gets you out of the water, too:
I would like to try one, if Dave Scadden is reading this.
