  • Designed for Comfort: The Fusion 50 makes your hike easier, whether you're hiking just a few miles or covering more than 30 miles a day. Its core structure combines Hip Belt, Spine and Shoulder Yoke into a stable and flexible frame system. With an easy to adjust torso length along with multiple sizes of Hip Belts and Shoulder Yokes, you can easily configure the Fusion for a perfect fit.

    Designed for Loads: The Fusion 50's light weight belies its load carrying capacity. Fusion Packs are designed to carry whatever gear you need comfortably. The advanced structure easily transfers weight to hips with no pack sag. Even under significant loads.

    Designed for Durability: To endure thousands of miles of rough terrain, The Fusion 50, is constructed with lightweight but high tenacity Robictm fabric. The exterior pockets are made from durable 4-way stretch fabrics. The pockets have depth so that they can hold a lot of gear.

    Designed for Usability: With seven exterior pockets and one internal security pocket, the Fusion 50 makes it easy to load your gear where it's quickly accessible. Side compression straps easily manage load volume without interfering with your pockets. Dual webbing tie downs easily secure a tent or sleeping pad.

Lovely sack

I hiked through a monsoon in British Columbia up Golden Ears with this thing for an hour, plus another hour with drizzels. I wasn't equipped with a bag liner or anything yet somehow all of my gear, food and clothing remained totally dry. I got the orange one and its a stylish beast. Compression works really well. Fits everything I needed for a couple night camp with friends. Awesome job, thank.

After trying way too many different packs over the years this one seems to do everything I need a pack to do. I like the traditional feel of the suspension coupled with the minimalist feel of the bag. The second generation Fusion 50 with it's improved side pockets, included harness pockets and what seems to be slightly larger bag volume fixed everything I wanted to change on my first gen Fusion 50. Design, comfort, durability and function, it has it all.

Fusion 50

The Fusion 50 is the best backpack I've purchased. It's my first Six Moons buy and will not be my last. Very comfortable while carrying heavy loads, or even just a few things on a short hike. Buy this pack and you will not regret it.

Very impressed

I wanted to try this pack out because I have a lunar solo that I absolutely love. A few years ago I got rid of all my internal frame packs and went to an old external frame pack that carried better than anything I had previously owned. As for the Fusion 50, the price Six Moon Designs was asking for it I thought why not give it a try. Well to be as light as it is I expected thinner materials, but the fabric is quite tough. The stretch material is stronger than anything I have ever used and should hold up quite well. The belt pockets are easy to access and bigger than I thought they would be. The harness pockets are handy to store a compass, and small GPS sized items. Everything I need for a 5 day hike fits inside the pack, and there is enough room left that if I attach the tent outside, ten days worth of food will fit fine. The five day weight plus water is 27 pounds. Amazing, its the lightest I've ever had a pack weigh. Can't wait to actually go hike some trails with it. Thank you Six Moon Designs.
