The Expedition Unisex backpack for alpine ski tours combines the highest function with a minimalist design at just 560 grams. With a volume of 30 liters, it is your perfect partner for alpine ski and multi-day tours. A roll-top construction functions simply, intuitively and quickly, which is extremely important on technical terrain. The 210D ripstop fabric used has an outer coating and is therefore very durable as well as weather resistant. The fabric plays to its strength precisely on high-alpine tours where you often scrape the rocks and there are constantly changing weather conditions. Thanks to its roomy 30L, the Expedition 30 has all kinds of space for your gear, while you can also quickly and easily increase or decrease the volume as needed with the roll-top construction.
