Orion 45L is a 45-litre mountaineering backpack that's lightweight and durable, designed for carrying heavy racks through Scottish winters and Alpine multi-day epics.

The stiffened back panel and padded back, hip belt, and shoulder straps provide all the support you need for carrying heavy loads. Load adjusters bring the pack's weight closer to your body on exposed sections.

At 990g, it's light for its strength and capacity, but maintains functionality. Ice axe retainers and a central pickguard keep them secure when not in use. Daisy chain webbing and hip belt loops give extra external capacity. Haul loops make the pack even more manoeuvrable.

Orion 45L is quick to pack and unpack with a drawcord closure. An internal hydration sleeve and port in the main compartment will fit a 3L water bladder. A PFC-free DWR treatment gives extra protection from showers and snowfall.

Sustainability & Care

Environmental impact

PFC-free DWR

We've used a PFC-free durable water repellent (DWR) on the outer fabric. PFCs are potentially harmful and have been found to build up in the environment.

Gear you'll love for longer

Increasing the lifespan of your kit reduces its environmental impact. We've use 420D ripstop nylon 66 and 840D reinforced nylon for increased durability
