Our Off Piste Ski pack is great for splitboarding and skiing and allows planks to be carried in an A-frame, cross carry, or split vertical carry. If you want to hardboard carry a snowboard or splitboard, you will need to purchase this carry strap to connect between the normal A-frame straps. This allows the pack to carry a sleeping pad or poles on the sides of the pack (or compress the pack) while still carrying a hard board. Most bags on the market you need to choose one or the other.
