    Fusion 50

    Love my Fusion 50 this is my second one, my second because I also recently picked up a Fusion 65 for winter camping. My first Fusion 50 has many miles on it and has plenty miles it on it but I liked the minor changes in the new model Fusion 65 that I got the new 50 because it's my GoTo pack. I have a Luna Solo tent as well you guys make good equipment.

    Great all around pack

    I've been using the Fusion 50 for 3 years on a number of different outings. Some weekends and others 7 days, this pack did them all with flying colours. I picked this pack since it wasn't that heavy and bulky but it could still take a heavy load if required. I've been out for 7 days and never had to worry about capacity, mind you I've switched out to light weight gear. I like the simple design and the layout out of pockets, perfect for jamming gear in and being able to retrieve without issue. Only two cons would be the primary waist buckle is small and I'm worried it will break soon. I plan on swapping it out. The second is the sun glass pockets on the shoulder straps, they are too high up, not a big deal. Other then that I'm very happy with the purchase its a great balance between ultra light and something that can be used in the shoulder seasons with heavy cold gear. Cheers good job Six moon crew!! Thanks for some happy trips. : )

    I used this pack for a 22 day, 540 km. trek in Turkey in November 2014. The pack carried a varied load of equipment/clothes, food and water very comfortably. I liked how the pack was easily adjusted. The straps on the bottom of the pack were very handy in storing my tarp/bug net system outside the pack. The roll top helped adjust the storage capacity when loading up with food in towns. The trail was quite bushy and the pack material held up very well.
