Blue Ice Stache UL 25L Alpine Climbing Backpack - Pearl Blue

The Stache UL 25L strips alpine climbing gear down to the essentials without sacrificing the features that matter when you're moving fast in the mountains. Unlike heavier packs that weigh you down on long approaches or technical routes, this 25-liter pack uses a frameless design with a removable foam back panel to keep weight low while still providing enough structure for comfortable carrying. The 210D high-tenacity ripstop nylon with water-resistant PU coating shrugs off rock abrasion and light precipitation, while the drawstring closure with top compression strap lets you cinch down a partial load or expand to fit a rope and extra layers.

Highlights

• Ultralight 25-liter capacity ideal for alpine climbing, mountaineering, and ski touring
• Removable foam back panel doubles as a sit pad and reduces pack weight
• Dual ice axe loops and A-frame ski carry system secure technical tools
• Top rope strap and side compression straps manage bulky loads
• Hydration sleeve with hose port keeps water accessible on the move
• Adjustable sternum strap with integrated whistle and removable webbing hip belt

In daily use

On a predawn start, the Stache UL 25L feels almost invisible—the frameless design and removable hip belt let you move naturally over scree and snow. The two gear loops on the shoulder straps keep a headlamp or GPS within reach, while the external stretch mesh side pocket swallows a water bottle or wet shell. Inside, a zippered security pocket protects keys and a phone, and the hydration sleeve routes a hose cleanly over either shoulder. When the route steepens, the dual ice axe loops and A-frame ski carry hold tools securely without snagging on rock. At belays, the top compression strap releases quickly to access the main compartment, and the drawstring closure cinches tight to keep spindrift out.
