Uncompromising Waterproof Performance for Overnight and Alpine Missions
Built for the rigors of winter mountaineering and demanding overnight backpacking trips, the Montbell Alpine Pack 40 seamlessly blends high-level weather protection with heavy-load carrying comfort. This 40-liter workhorse features Montbell's highly water-resistant Aqua Barrier Sack combined with a Roll-Up Closure System, ensuring your essential gear stays completely dry in punishing conditions. Engineered with the Super Wishbone System, the pack utilizes an adjustable aluminum frame to precisely transfer weight to your hips, delivering a fine-tuned fit that moves with your body on technical terrain.
Key Features
- Roll-Up Closure System: Provides rapid, wide-mouth access to the main compartment and features pocketable side buckles to securely fasten the roll-top down the sides.
- Aqua Barrier Sack: An integrated, highly water-resistant liner (covering both the main body and top lid) that delivers exceptional waterproofness without the need for a separate rain cover.
- Super Wishbone System: Features a highly adjustable internal aluminum frame that stabilizes heavy loads and transfers weight efficiently to the articulated hipbelt.
- Adjustable Torso Length: The shoulder harness can be dialed in to accommodate three distinct back lengths (19.3", 20.8", 22.4") for a perfectly customized fit.
- Convertible Top Lid: Easily detaches and transforms into a standalone waist pack or sling bag (strap included) for minimalist side trips.
- EVA Foam Back Panel: Delivers premium cushioning against the spine while offering excellent breathability and quick-drying properties.
- Advanced Gear Storage: Equipped with a 2-way accessible side pocket (reachable while wearing the pack), an ice axe/pole strap, and side compression straps to secure long items and keep the load tight against your center of gravity.
- Hydration Compatible: Fully equipped to house your hydration reservoir for hands-free drinking on the move.

Care & Maintenance
To preserve the structural integrity of the Super Wishbone frame and the waterproofing of the Aqua Barrier Sack, please follow these guidelines:
- Cleaning: Do not machine wash. Spot clean dirt, salt, or mud using a soft sponge dampened with lukewarm water and a mild, non-detergent soap.
- Drying: Wipe off excess moisture with a clean towel. Hang the pack to air dry completely in a well-ventilated, shaded area. Strictly avoid direct sunlight and artificial heat.
- Storage: Store in a cool, dry place. Ensure the pack and the interior Aqua Barrier Sack are 100% dry before storing to prevent mildew and the degradation of the urethane coatings.
Customer Reviews
Overall rating: 4.9 / 5 from 255 reviews.
Size fits as per chart. Good stitching overall & ventilation very good. Haven't tried in wet weather just yet but likely to be working excellent. Stores very easily in running waistband and thoroughly recommend. Previously tried Adidas, Ciele, and Rabbit - this is way better.
The size is just nice to put the necessities. It is also light.
Awesome

Bought this strap to attach to my Montbell hat, the strap is of high quality and the adjustment of the buckle is smooth and easy.
Material looks good, I have used their short sleeves before and it works very well in hot and humid weather. Now trying out their long sleeves and would expect it to be the same.
