The best got better
The trusted packs that started it all—now reimagined with new Dyneema® Woven Composites for unparalleled durability and performance.
Introducing all-new Dyneema® Woven Composite fabrics
We’ve partnered with Dyneema® to become the first to integrate their groundbreaking Dyneema® Woven Composite into our core pack line—delivering lighter weight, greater strength, and proven performance in the world’s toughest terrain.

Doubling Down on Durability
Dyneema® has pushed fabric engineering by doubling the Dyneema® in its latest composite material. The new Dyneema® Woven Composites utilize signature Dyneema® fiber on both the internal and external layers, creating an advanced composite with unmatched performance.

Quantified Advantage
Engineered for the most demanding conditions, Dyneema® Woven Composite delivers up to 10x more abrasion resistance, 5x better tear resistance, and up to 34% weight savings compared to the existing Dyneema® high-performance fabric composite portfolio.

Strength in Practice
“With the new Southwest pack… I don’t need to hesitate. That extra confidence allows me to move into more and more aggressive and adventurous mindsets, spaces, and aspirations.”

Key Upgrades for Elevated Performance
While the heart of our core packs remains unchanged, we've meticulously refined key elements to elevate performance and comfort, ensuring these packs continue to set the standard:

Enhanced Carry Comfort
Redesigned shoulder straps and a sewn-through back panel provide a more comfortable and secure fit, with better weight distribution and less wear over time.

Improved Storage Access
Redesigned outside pockets with more depth, lower back edges for easier access to water bottles, and improved security for gear (like the ice axe) make packing and accessing items more convenient.

Customizable Compression Straps
New, removable compression straps with adjustable positioning and added daisy chains allow for easier organization and the ability to secure additional gear.
