Skis/Board: this may be stating the obvious but make sure you have the correct skis/board and bindings for touring – a short park board or stiff racing skis won’t be suitable for backcountry terrain.
Skins: without touring skins on your skis or board you’re not going to be able climb at all, don’t forget them or it’ll be a tough hike out.
Boots: saving weight is key for touring – having lightweight touring specific boots will make your climb up much easier, especially if the face is too steep for skinning.
Backpack: you could be out for an hour or for a full day, bring a backpack to stash all your kit in.
Poles: it might feel a bit strange snowboarding with poles but you won’t be able to tour without them – ideally take an adjustable set that can pack down and attach to your bag for descents.
Clothing: the backcountry can be a wild place, dress appropriately. Invest in some technical outerwear and mid-layers – keep spare gloves, socks and extra layers in your backpack.
Navigation: bring an up to date map and working compass or a functioning GPS system, the weather can turn very quickly and you want to be able to navigate through a storm.
Safety & Rescue: First-aid kit, transceiver, probe and shovel – you may never have to use them but bring them nevertheless and know how they work.
