The Original Outdoor Outfitter®


2012 Outside Gear of the Year Award Winner.

A tough alpinist pack, our Alchemist 40 has been honed to handle exactly the tools necessary for reaching big objectives. The expandable design hauls what you need to base camp, then straps down into a smaller pack for the final summit push.

"This shape- shifter might just replace every pack you own.
For sheer day-in, day-out versatility, the Alchemist proved the best of the bunch."
Outside Magazine

As seen in the Men's Journal Gear Lab Collection
"The Alchemist 40L is the most versatile pack available, able to transform itself to fit any adventure. In standard's perfect for day hikes and peak bagging. Looking to escape on a longer trip? It morphs into a 55-liter pack capable of swallowing a multi-day trek's worth of gear."

"The Alchemist 40 is simple to use, lightweight and carries heavier loads well. I also can't imagine a better pack for versatility. If you are establishing a high camp and then going for a lighter-weight summit day, this is the expandable pack for you."

Decided to return it (just a style reason)


We decided on a less "obvious" tourist backpack, so we will need to return it.


Bomber pack!


This is such a nice bag! Top quality bag with some clever features! As a gear junkie I've owned a ton of packs over the years. This one has me impressed! Some of my favorite features are BFD pad on the back panel. Perfect for setting on snow. The material is very sturdy and highly water resistant! I mainly use this as a snow pack. XC skiing, and snow shoeing. Not as a snowboard pack but You could probably use it as one in a pinch if you run some board straps through the daisy chain. Theres kind of a hidden pocket towards the back of the pack that will acomadate a snow shovel' which is nice. Have not used the extended version of this pack yet, but looking forward to it. Only ding I have is that couldn't find a hydration port? But I just run the hose through the main zipper, no biggie. Another great EB product!




It's treated me good. Hiking and cross country skiing.


I've used the pack on a couple longer hikes and it's been great. One of the hikes was a winter ascent and needed to pack the shovel. Not really any good spots for a shovel but I was able to rig something to the hooks on the front. I love how it expands. I can keep things tight when I don't have as much gear or remove something large. Not sure sure how it would manage overnight with a tent and or sleeping bag inside. I'm guessing you could get away with it during the warmer months but it would be a struggle during the spring and fall.

Wonderful bag


Love the bag. Just wish they had shipped the right one the first time. Now if they only had mens Igniter Pants in stock. They've been sold out or only have had one size for years.
