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

"The Alchemist 40L is the most versatile pack available, able to transform itself
to fit any adventure. In standard configuration… it'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."
