The Terra Incognita Action is a 35L (expandable to 45L) multi-sport backpack built for climbing, ski touring, and fast hiking, with a ventilated 3D suspension system that keeps your back cool on hard efforts. Made from 420D ballistic polyester with a reinforced 1680D nylon base, it is a durable mid-size pack sized for day missions and light overnights where you move quickly and need the load to stay stable and breathable.
Who is the Action backpack designed for?
The Action is made for multi-sport users - climbers, ski tourers, scramblers, and fast hikers - who want one durable pack that adapts across activities. The 35L-to-45L range hits the sweet spot for a full day out with rope, layers, food, and safety kit, or a stripped-down overnight. If you value a cool back and a stable carry over maximum capacity, this is the pack that fits.
How does the Action backpack ventilate your back?
The ventilated back panel and 3D EVS suspension are the standout on steep, sweaty ground: air moves between your back and the pack instead of trapping heat. The anatomical hip belt transfers weight onto your hips so your shoulders stay fresh, and the hip pocket keeps essentials handy without stopping. Cinch it to 35L for a light day or open it to 45L when the kit list grows.
What materials make up the Action backpack?
The main body is 420D ballistic polyester, a tightly woven fabric chosen for abrasion resistance against rock and equipment, while the base is 1680D nylon FTX - a heavy, reinforced weave placed exactly where a loaded pack drags and drops. This construction targets the failure points of lighter packs, so the Action holds up to repeated seasons of climbing and touring abuse.

Questions & answers
Action backpack FAQ
How big is the Action backpack?
The Action is a 35L pack that expands to 45L. That range covers a loaded day out with technical gear and stretches to a light overnight, making it flexible for climbing, ski touring, and fast hiking without owning two separate packs.
Does the Action have a ventilated back?
Yes. It uses a 3D EVS suspension system with a fully ventilated back panel. The design lifts the pack off your back so air can circulate, which keeps you noticeably cooler on steep climbs and warm-weather efforts.
How much does the Action backpack weigh?
It weighs 3.57 lbs (1.62 kg). That is a deliberate balance - light enough for active multi-sport days, but built with ballistic polyester and a reinforced nylon base so it can take rough handling on rock and snow.
Is the Action durable enough for climbing and ski touring?
Yes. The body is 420D ballistic polyester and the base is 1680D nylon FTX, both chosen for abrasion resistance. The reinforced bottom protects the highest-wear area, so the pack stands up to rock contact, ski edges, and repeated heavy loads.
Does the Action have a hip belt pocket?
Yes. The anatomical hip belt includes a storage pocket, so you can keep snacks, a phone, or small essentials within reach without taking the pack off. The belt also transfers load onto your hips for a more comfortable carry.
