As stated, we have tried the new Alchemist 40 and also the Sisu 40, the Sisu is my preference but not by much. I originally rated the Alchemist before hiking it, my mind changed quickly but I can not revise my review. Both bags will receive an overall 4-Star, but the Sisu is the less of the two evils. What I do not like about the Alchemist 40: The load weight distribution is very top heavy, it tapers and narrows towards the bottom, and the Corner Zippers are frustrating. The squared corners are hard to zipper without anything inside, once you pack the bag the corners become almost impossible to close without fear of tearing the seam. The taper design is very difficult to properly load. The expansion area to 55L is not weather resistant, the oversized fabric is too thin to keep the content protected. Now on to the Sisu. My greatest complaint about this pack is the Upper Hood Retention hook, it needs a secured mechanism to close the opening. My anticipated fear came true on seven out of eight legs of our recent travels. When we were awaiting the bags on the arrival carousel I saw the Sisu come through the corner and the hood was detached and open. Thankfully there is a secondary quick strap to keep the contents inside. The only time the bag maintained the outer hook was the flight where are pack was maxed out and full. EB, please develop a secured closure hook, this open ended hook is a failure. The rest of the Sisu is spot on. Exterior attachments are adequate and well placed. Interior load space, designation, and carry capacity is perfect. Weather resistance is excellent with the 600 denier fabric. Each bag has its flaws, for me the open hook on the Sisu is the lesser drawback when compared to the several short-comings of the Alchemist. Daniel

This pack has a lot of potential. That being said, I had to return it after about 30 days. The speed buckle completely detached from the bag making the buckle inoperable. (this is the 3rd pack I returned in the last couple months)

I really wanted to love this pack. I was immediately impressed when I saw it in store. While a little heavy, it seemed great for backcountry snow adventures and mountaineering. Things I love about this pack: - Burly fabrics throughout. - Innovative ice axe shaft holders that can easily be released with gloves. - Dedicated, easy-access snow tools pocket. - Removable crampon pouch (admittedly, it's a little small). - Very comfortable with 35+ pounds. - Tons of mounting points. The side straps can be used to lash skis, snow shoes (see pics), tents etc. - Great climbing features, like the helmet holder, gear loops, crampon pouch. With that said, there are some glaringly obvious problems with this pack: - The hook on the helmet holder is too small for the webbing it's supposed to attach to. The main pack lid has a larger hook which fits perfectly. The helmet holder's hook easily comes undone when moved. - The port for the water bladder hose is on the opposite side to the shoulder strap that has the retaining webbing. - The pack is assembled with mostly water-shedding materials. The red/black fabric is super hydrophobic and is basically waterproof. The red nylon is less good at shedding water, and wets through after a short time. Overall pretty good, although I have no idea why the burly and waterproof red/black was used on the pack lid and not on the bottom of the pack, which will cop more abuse and water. - The water resistance of the pack is let down by the choice of zips. The lid, which is entirely constructed of near-waterproof materials, has fabric zips with no water resistance at all. More significantly, the heavy gauge zip on the back of the pack is completely uncovered, which will lead to rain and snow settling directly on it, and going straight into the pack. Sadly, after all this, I'll likely return the pack. Given its price tag, it's too risky to cross my fingers and hope it's not as bad as it seems. I'd love a version 2 of this pack with the issues fixed!
