Osprey Atmos Ag Lt 65l Rygsæk

This is by far the most comfortable backpack I’ve ever worn. I’ve used about 6 different packs over the years, and this is another level of comfort. It’s very forgiving, too, meaning you don’t have to perfectly dial in every strap to get comfortable. My torso measures 18.5”, and a S/M is perfect for me. The built in rain cover is generously sized to cover the fully loaded pack with some gear strapped on outside

This pack had a lot of good features and seemed to be made of really good materials. I really liked the trampoline mesh back panel. The only issue I had was when it was loaded, every time I walked the hip belt squeaked. This started about a mile into the trail. It drove my friends and I nuts! I took it to REI to exchange but they didn’t have this exact model in stock. Bummer. I traded it for an Osprey Atoms AG 65 (not the LT model) and it seems nice.

I chose this Osprey over other brands because it features the AG Anti-Gravity system, and wow, it didn't disappoint. For backpacking in a climate as hot and humid as Puerto Rico, it was definitely the best choice.

Finally got a chance to use this on a recent trip to the Sierra, needed the extra room and weight capacity for all the winter gear and the pack handled 45 Lbs. like a champ. After fiddling with the adjustments I landed in a happy spot that allowed me to put down some mileage without feeling too strained. I would really grade it at 4.5 stars, docking it a halfer for the waist belt being a bit bulkier than I wanted it to be, making the ventilation work a bit less effectively as a result. For comparison purposes, my Exos 58L (3rd gen w/o the belt pockets) fits seamlessly on my hips and vents better. At ~4 Lbs it's not super light, but there are some nice thoughtful touches throughout the pack and construction looks like it will withstand a nuke. Overall, a great pack for trips that demand a heavier load.

Very good and comfortable pack. Highly recommended.
