There’s not a ton of information on this pack yet. Hopefully I can assist potential buyers in making a decision.

FWIW, I’m 5’8” (1.73m) 200lbs (90.7kg) with a muscular build. I’ve done two 10k hikes with this pack. One with my typical 20lbs (9kg) TPW and one at 27lbs (12.25kg). I have a size medium Aerus.

Materials and craftsmanship are among the best I’ve come across.

It carries weight extremely well. I had to re-weigh my pack after the initial hike to make sure it was 20lbs because it really didn’t feel like it. The 27lbs pack was incredibly comfortable and felt lighter than its actual weight. The load lifters are effective.

The arc is very effective at venting while not being unstable or feeling too far away from your back. It has been hovering around 97F (36C) here with high humidity and I could feel the breeze evaporatively cooling the sweat on the back of my shirt.

The straps and waistband are perfectly positioned and contoured for me and more comfortable than other packs I’ve used. Namely Gorilla 50, Kakwa 50, and HMG Southwest 55.

The lowest carbon fiber cross member was noticeable through the lumbar pad. Not too uncomfortable, just noticeable and that kind of got stuck in my mind while hiking. I removed it and the pack became more comfortable for the second hike and it didn’t noticeably lose any form or rigidity. I ok’d this with Bonfus as well.

The volume is what I would expect from a 55L pack. Front pocket is big enough to hold what you’d want it to hold and not so big that it allows overpacking that can lead to instability from having too much weight far from your back. The side pockets are large enough to hold two 1L Smartwater bottles each with a little room to spare.

Dislikes. If there is only one 1L bottle in each pocket they will easily fall out of the side pockets when leaning forward at a near 90° angle (tying shoes for example). The compression straps are not low enough to secure the tops of the bottles. The pack will not stand up on its own and needs to be leaned against something to keep it upright. No option to fold the roll top down and secure it on the sides. It only secures “up”.

Concerns. The spot where the side pocket is sewn to the front of the pack is also where the front pocket is sewn. This seems to be a high stress point even with a reasonable amount of gear in the side and front pockets. I’ll have to keep an eye on this spot. Because the pack will not stand up on its own, I worry about additional wear from leaning the pack on things or laying it down. Specifically extra wear on the front mesh pocket or the nylon webbing that holds the bottom of the stays in the pack.

In the end, this is the pack that I’ve been happiest with right out of the gate. It ticks so many boxes and has only a very few compromises.
