Designed for long days in the mountains where speed, access and stability matter, the Silva Strive Mountain Pack 23+3 is a lightweight, body-hugging backpack built specifically for ski touring, ski mountaineering and fast alpine adventures. Drawing on Silva’s experience in endurance sports, it blends the close fit of a running vest with the carrying capacity and durability required for serious winter missions.
With a 23-litre main capacity and an additional 3 litres of expandable space, it hits a sweet spot for full-day tours, technical ascents and lightweight hut-to-hut trips.
Built for Movement in the Mountains
The Strive Mountain Pack 23+3 is all about stability when you’re on the move. The vest-style harness wraps securely around the torso, keeping the pack close to your body and minimising bounce.
The result is a pack that feels far more controlled than traditional backpacks, particularly when you’re moving fast or carrying skis. For ski tourers who value efficiency and balance, that snug, athletic fit makes a noticeable difference over a long day.
Smart Storage, Fast Access
Silva has clearly designed this pack with real mountain use in mind. The layout prioritises quick-access storage, so essential items are always within reach without stopping to unpack. The expandable 23+3-litre capacity gives you flexibility: compact and streamlined when lightly loaded, with extra space when you need to carry layers, safety kit or food for longer days.
Dedicated compartments help keep gear organised, while the clean internal layout makes it easy to pack efficiently a small but important detail when you’re dealing with gloves, cold fingers and changing conditions.
Ski Touring Ready Design
This is a pack built for ski touring from the ground up. It’s compatible with ski carry systems, allowing you to secure skis when boot-packing or scrambling. There’s also space for essential safety equipment, making it well suited to off-piste and backcountry use where avalanche gear is non-negotiable.
The streamlined shape means nothing catches or flaps when skiing downhill, and the pack remains comfortable even when fully loaded — something that’s often overlooked but hugely appreciated on longer tours.
Comfort for Long Days
Comfort is where the Strive Mountain Pack really stands out. The vest-style shoulder straps distribute weight evenly across the upper body, reducing pressure points and fatigue. Breathable materials help manage moisture during high-output climbs, while multiple adjustment points allow you to fine-tune the fit depending on layers and conditions.
It’s a pack that feels designed to be worn all day, not just carried from A to B.
InTheSnow Take
The Silva Strive Mountain Pack 23+3 is a premium ski touring backpack for skiers who prioritise movement, stability and smart design. It combines the close fit and accessibility of an endurance vest with the capacity and toughness needed for real mountain days.
If your touring involves long climbs, technical transitions and fast descents and you want a pack that stays put and stays comfortable this is an excellent choice.
