If you’re in the market for a new pack, or if you regularly recommend models to others, I genuinely believe that the Flex Capacitor is worth consideration. I would insert it into the same conversation as the Osprey Exos, ULA Catalyst and Circuit, Gossamer Gear Mariposa 60, and Granite Gear Blaze and Crown. These packs weigh 2-3 lbs, are made of durable fabrics, and remain comfortable when loaded with a week of food and a bear canister.
The most significant advantage of the Flex over these other packs is its volume adjustment: with just an extra few ounces of build, it covers the same range as two conventional packs. It’s also only $200, which is very competitive.
I’ve been singing the Flex’s praises for a while, but I would completely understand any skepticism given my involvement with the project. But I’m hoping that Gear Junkie’s endorsement will help convince you. And if you want even more, read Paul Manganti’s first impressions and the user reviews (so far, a perfect 5/5) on the product page on SD’s website.
Ultimately, the “best” pack is the one that wears most comfortably, satisfies most of your needs, and that is within your budget. It may not be the Flex Capacitor, or it may be. Give it a chance.
