For backpacking, thru-hikes and alpine expeditions, the Ariel AG™ Series has a pedigree like no other pack. We have set the bar for technical backpacking packs by combining Anti-Gravity™ technology with customizable fit and innovative features like our new convertible top lid to create a more capable and comfortable pack for long-haul load carrying on any multi-day excursion. When you need a pack that can carry heavy loads for up to a week, there is no better option than the Ariel AG™ pack. Size XS comes with a Small hipbelt and harness.
Don't recommend - frame too long for shorter statures
I normally use a size small Aura 65 pack. The frame on the size small Ariel 65 is at least two inches longer than on the Aura, and made a noticeable difference in comfort when using it on a 7 day 70 mile trip. I have heard that this pack is meant to sit lower on the hips. I am used to being able to sit my pack closer to the waist above the hip bone to relieve pressure on the shoulders, but this was impossible with the Ariel. I experienced a lot of hip pain while using it. The lack of external pockets in comparison to the Aura model means that everything has to go inside the main compartment, which makes it more difficult to access things you want every day without unpacking the whole bag.
