  • .. the Fusion 65 is certainly one of the best lightweight packs around for those who sometimes carry more than ultralight loads.

    Designed for Comfort: The Fusion 65 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 65's lightweight 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 65, is constructed with lightweight but high tenacity Robictm fabric. The exterior pockets are made from durable 4-way stretch fabrics. The pockets lay flat to reduce snags on cross-country routes, yet expand to hold a lot of gear.

    Designed for Usability: With seven exterior pockets and one internal security pocket, The Fusion 65 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.

    Comfort, Durable and lightweight

    I've used this pack for 1,000 miles and it shows no signs of wear. It even sheds dirt well. It's roomy enough for all my gear plus fly fishing tackle, nine days of food and with this heavy load is still comfortable to carry. The side pockets are deep to allow me to have a fishing rod, umbrella and camp shoes with adjustable straps to keep them in place. In the large outside pocket, I have my rain gear and water treatment for quick access and room for more. It's a wonderful pack for the long haul with a big load!

    Fusion 65

    This is a fantastic pack—huge amounts of room. I’m 6’5”, 250, and my clothes and gear are all outsized.This pack takes it all. The large harness fits well, with tons of adjustment room left on every strap. They’ve thought of everything, from 6-way fit adjustment, to a hydration pocket, a security stash, and pockets and attachments for everything you’ll need. I was set on an Osprey, but I’m so glad I went with this product. I saved a pile of money and feel I purchased the better product. My wife and I also use the Lunar Duma Explorer, which is a fantastic tent. Six Moon Designs know exactly what the outdoors enthusiast wants and needs, and they exceed expectations with their products. Can’t say enough about the company and the gear.

    Trail Ready!!

    Haven’t gotten out on the trail yet, but I can already tell how sound this design is. We cover a lot of miles and needed a pack that could hang in for the long haul. This pack is clearly designed by people who know the nuances of long treks. Lightweight, yet durable. Easy carrying even with gear for em and the dog. Stoked to hit the mountains!!

    Love it!

    Just got back from Minam Lake. Pack handled a 37 lb load no problem. Weight never shifted when crossing streams and post holing through snow. Pack was extremely comfortable to carry.
