After 16 years of using a North Face Big Shot for my go to daypack and travel pack it was time to look for a new pack. After several months of searching for a similar size pack I came across the Alchemist 25/35. I was originally intrigued by the simple appearance, yet technical features. I was unable to find an in depth youtube review but ordered the pack anyways. The Alchemist is constructed of durable polyurethane coated nylon that sheds rain and snow, keeps contents dry, and is easy to clean. The zippered pouch on top is easily accessible, of decent size, good for snacks and essentials, and has a secondary zippered mesh pocket inside. Each side has an expandable water bottle pouch. The main compartment expansion feature took a little time to figure out, but dramatically increases the versatility of this pack by allowing for extra gear storage. Climbing one weekend, day hike the next, visiting family for two nights the next, a bike ride the next, one - two night backpacking in the mountains after that (if you pack light). The molded back panel is comfortable and breathes well. The shoulder straps and waist belt are wide, comfortable, and breath decently. The pack is designed so that it fits close to the body and moves with you. Now onto the straps. This pack is geeked out with straps and slides, which is great for strapping on gear, and compressing the pack down to keep the weight close to your body. However, upon first using the pack the number of straps and slides was a little much, but with time one gets used to taming them. Six of the slides are designed to unclip from the loop, perhaps for easy replacement if they break. The two quick release strap buckles are a neat feature. If weight is a concern, this is not a light pack for its size. It does have a removable plastic stiffener that allows the pack to stay upright and not slouch over when digging through it. Overall I am very content with the design, the features, and the durability. Nice job design team.
