The Arcteryx Altra 75 LT Pack is a solid backpacking/trekking pack that is designed for 3-7 day long hauls. They have come out with new suspension and fabric technologies over the years and this pack utilizes all of them. I've used the Altra 75 LT on winter camping trips with snowshoes lashed onto the sides (when not lashed to my feet) and I've used it for summer camping trips to the beach, loaded up with like 80lbs (including a 30 case of beer under the adjustable lid). The combination of the Load Transfer Disc™ and C2 suspension with Gridlock™ shoulder straps (which adjust for a custom fit) allows it to hold everything perfectly, evenly distributing the weight across the hips and shoulders. The kangaroo pocket with a "U" zipper allows you to access your pack's contents without pulling everything out.

ARC'TERYX MEASUREMENT GUIDE
How to Find Your Foot Measurements
Arc'teryx packs are sized either in 3-length options: Short (S), Regular (R) and Tall (T), or in 2-length options: Short/Regular (SR), and Regular/Tall (RT).
Sizing refers to YOUR OWN BACK LENGTH
Measure your Back:
• Measure along the spine between the 7th cervical vertebra and the level of the hip iliac crest
• Compare this measurement to the Sizing Charts
• It is possible to interchange different size shoulder strap and hipbelt components on many Arc'teryx Packs, but this will not change or affect the back-length of the pack.

Hip belt broke on first trip, very surprised and disappointedThe Altra has many great design features, but I can't ignore or accept a broken hip belt after one trip. The hip belt is attached to the pack frame by circular plastic coupler called a "rotating load transfer disk" which allows the hip belt to move as the pack shifts. It's a great idea and worked well while it lasted, but one of the plastic tabs that keep the hip belt attached to the pack broke off. I only used the pack on one trip and did not abuse it at all. I am very surprised that the pack failed so quickly, especially considering my excellent past experience with Arc'teryx products. I contacted Moosejaw and was told I need to call Arc'teryx. I'm extremely disappointed with the product and Moosejaw's service.

Great Pack!I have a several packs including Gregory, Mountain Hardwear and Cilo. The Arcteryx is my work horse and does the job well. I haven't heard any "sqeaking" from the pack but then again it comes with "grease" so problem solved. In terms of dimensions I am 5'9" with a back measurement of 19.5 and I got the short/regular. It fits great mainly due to the fact you can adjust almost everything on it! Very well though out and solid material. Lighter and actual seems smaller that it really is.

Better than the Bora'sIt is evident that a lot of R&D was put into this pack. With both panel loading and top loading ability, it easily adapts to your packing style.,,The shoulder harness is fully adjustable up top through gridlock system. It is field adjustable, but it can take some effort to get the pins locked into place. The pockets on the side will. technically, hold a nalgene bottle, but I would not recommend it. The bladder pocket is now centered on your back and will hold a 3L bladder.,,The load transfer disc, the elephant in the room. Yes it squeaks.I put half a tube of grease on it and it was still doing making noise. That being said, this will go down as one of the greatest innovations in backpacking. It only took a small hill and 100 yards before I knew that they had struck oil on this one. It's noisy, but it works like a f'ing champ. Its is also removable. Flip it around the pack for travel and for laying flat in the field.
