Why it's on GiftsFeed
Backcountry ski pack engineered for rapid transitions and extreme durability
Most ski packs make you choose between bombproof construction and low weight, or between organized gear access and simple design. The Crux 40 uses Dyneema composite specifically because it withstands the punishment of ski edges, crampon straps, and ice tools without the weight penalty of burlier nylon—crucial when you're moving through technical terrain where a torn pack means bailing on the objective. The rear-panel zipper is the deciding detail: you can access everything inside while standing on a bootpack track barely wider than your skis, without dropping the pack in the snow or losing your place in line. That combination matters for anyone who spends days in exposed alpine zones where efficiency and durability aren't luxuries.
Good gift when
- Ski mountaineers who prioritize speed and efficiency in alpine terrain
- Backcountry skiers tackling long approaches with technical descents
- Splitboarders needing durable gear for multi-day tours
- Anyone who values quick access to safety equipment on steep slopes
Skip it if If you need dedicated hydration sleeve access or prefer packs with external mesh pockets for wet gear, this streamlined design focuses on durability and tool organization over convenience features.

The maker
Hyperlite Mountain Gear collaborated with Cody Townsend during development, refining features based on his experience filming and climbing peaks across North America. The result prioritizes what matters during long approaches and exposed descents: tool security, material toughness, and access that works when you can't afford to fumble. Every element serves skiers who measure day length in vertical feet and terrain difficulty rather than trail miles.
The details
The Crux 40 solves the problem every backcountry skier faces when seconds count: getting to your gear without taking off the pack. A full-length zippered back panel opens the entire main compartment while the pack stays on your shoulders, so you can grab layers, water, or food in steep terrain without the usual fumbling. Internal pockets sized for avalanche tools keep probes and shovels organized and separate from the rest of your load.
Built from Dyneema Woven Composite 5.0, this pack resists abrasion from ski edges and crampon points far better than conventional nylon. The material's tear strength matters when you're lashing sharp metal and carbon fiber to the outside through hundreds of transitions. A-frame and diagonal carry systems accommodate skis or a splitboard, with compression that keeps them secure during scrambles.
The drawstring collar expands to swallow rope, extra layers, or bulky insulation, and the removable lid converts the pack from fixed-volume to extendable depending on the objective. Torso sizing ensures the hip belt carries weight properly whether you're bootpacking or skinning for hours. At 40 liters, capacity suits single-day missions and overnight trips when you pack light.
Co-designed with Cody Townsend for technical alpine touring and ski mountaineering

Questions
- Does this pack fit a snowboard as well as skis?
- Yes, the A-frame and diagonal carry systems work with splitboards. The compression straps secure boards during approaches and scrambles.
- How do I measure torso length for sizing?
- Measure from the C7 vertebra at the base of your neck to the top of your hip bones. Small fits 15-17 inches, Medium 17-19 inches, Large 19-21 inches, and Tall 21-23 inches. Proper fit ensures the hip belt sits on your hips to carry weight effectively.
- Can I access gear without taking the pack off?
- Yes, the full-length back-panel zipper opens the main compartment while the pack stays on your shoulders, allowing you to reach items inside without removing it in steep or exposed terrain.
- Is the Dyneema fabric waterproof?
- Dyneema Woven Composite is highly water-resistant but not fully waterproof at seams. It repels snow and light moisture effectively, though extended exposure to rain may require additional waterproofing for sensitive gear.
- What fits in the internal avalanche tool pockets?
- The internal pockets are sized to hold a collapsible avalanche probe and a folding shovel, keeping them separate from other gear for quick access during emergencies.
