Most versatile pack with both shoulder strap & vest harness options, durable, proven design — 10 years in production

The Six Moon Designs Swift X Backpack is the only pack in this guide to offer a vest harness. The vest harness has significant benefits. 1) it allows you to move weight forward for a more balance load. So less leaning forward to balance a back-heavy pack. And 2) it gives you a lot more accessible storage. So you have greater access to all your stuff without needing to stop and take your pack off — making you more efficient on the trail. (Checkout our Pro Tip on pack pockets — we’re big fans). The Swift X Backpack is also the most versatile pack in this guide. The pack is adjustable to a number of torso sizes, the hipbelt comes in a number of sizes and designs, as do the shoulder straps, and there is obviously a vest harness with tons of pockets and storage. You can mix and match all of these. And you can choose from three fabrics, Liteskin LS07, X-Pack VX07 and X-Pack VX-21 Amazingly the pack still comes in at just 36 to 37 oz for a fully featured pack with a frame.
