With a 37-litre optimum capacity and custom-developed fabrics and aluminium hardware, the Tupilak 37+ is a lightweight, highly weather-resistant, durable climbing mountaineering pack for summer alpinism and winter climbing on the steepest lines. Developed through more than 35 prototypes, every aspect of design and functionality has been individually tested and assessed by us, our pro partners and a hand-picked group of professional mountain guides.

Like all our Tupilak packs, the Tupilak 37+ uses custom-developed high tenacity PACT™ 300 and 100 R² fabrics. These are lightweight but highly robust and weather-resistant fabrics, easily repelling snow and withstanding even the most severe mountain conditions. An integrated cowl-lid closure with a custom-developed Grappler™ buckle further seals out the weather and is easy to use in poor conditions. In contrast, a secondary internal roll-top closure provides additional weather protection and allows you to keep wet and dry items separate.

A streamlined hourglass shape facilitates packing and offers a more stable carry for hiking and climbing, while an EVA back panel provides support and improves comfort. Similarly, high-density EVA foam shoulder straps are low profile to facilitate climbing mobility but offer excellent carrying performance on long walk-ins. Side compression straps with lightweight aluminium buckles improve load stability and can accommodate items such as sleeping mats or even skis. Likewise, aluminium ice axe toggles and bungee cord systems offer more significant carrying potential. To shed weight for challenging ascents or summit pushes, the back panel, hip fins, compression straps, bungee and ice tool toggles can all be stripped if not required.

A zipped floating pocket for items like head torches and sun cream can be accessed from both outside and inside the bag.
