The Terra Incognita Impuls 40L is a durable, multi-sport backpack built for rock climbing, hiking, and ski touring, aimed at active users who need one rugged pack that crosses seasons instead of a shelf of single-use bags. It pairs a 420D Polyester Ballistic body with a 1680D Nylon FTX reinforced bottom and a 3D EVS suspension that spreads the load, delivering a 40L capacity that carries a full climbing or touring kit at a trim 3.46 lbs.
Terra Incognita is a European brand with more than 18 years of expedition experience and its own gear production, and the Impuls reflects that heritage with load-bearing details built for real routes: ice tool attachments, trekking pole loops, hydration compatibility, and a ventilated hip belt with a storage pocket. If you want durable backpacks that handle a via ferrata, a summer trek, and a backcountry ski day with the same pack, this is that pack.
Who is the Impuls backpack made for?
The Impuls fits climbers heading to multi-pitch and crag days, hikers on hut-to-hut and overnight routes, and ski tourers who need to strap on tools and move fast. Its 40L size is the sweet spot for a full day out or a light overnight, big enough for a rope and layers yet compact enough for scrambling. If you practice more than one mountain sport and want a single pack that does all of them, this is built for that crossover.
What fabric is the Impuls backpack built from?
The body uses 420D Polyester Ballistic, a tightly woven fabric chosen for abrasion resistance, while the base steps up to 1680D Nylon FTX, the thickest and most wear-prone-friendly material in the pack. That two-tier construction puts the toughest fabric exactly where a climbing and touring pack grinds against rock and ice, so the bottom outlasts the rest instead of wearing through first. At 3.46 lbs, it stays reasonably light for its durability class.
How does the Impuls backpack carry on an approach?
On the approach, the 3D EVS suspension and ventilated hip belt carry the load close and cool, while the anatomical straps reduce shoulder fatigue. At the base of a climb you can lash ice tools and poles to the external attachments, sip from the hydration system without stopping, and reach snacks from the hip belt pocket. For ski touring, the same attachment points hold your tools and the durable fabric shrugs off edges and crampons.

Questions & answers
Impuls backpack FAQ
How big is the Impuls backpack?
It holds 40L, about 10.6 gallons of capacity. That is enough for a full day of climbing, a long hike, or a ski tour with layers, food, and safety gear, and it works as a light overnight pack when you carry compact sleep and shelter systems.
Is it tough enough for rock climbing and ski touring?
Yes. The body is 420D Polyester Ballistic and the bottom is reinforced 1680D Nylon FTX, so the pack resists abrasion from rock, ice, and rough ground. The tougher base material sits exactly where a climbing and touring pack takes the most wear, which extends its working life.
Does it work with a hydration bladder?
Yes. The pack is hydration compatible and includes a dedicated valve port, so you can run a reservoir and drink hands-free on the trail or the skin track. Combine it with a compatible bladder to keep water accessible without opening the main compartment.
How much does it weigh?
The Impuls weighs about 3.46 lbs. That is light for a 40L pack built with ballistic polyester and a reinforced nylon base, striking a balance between all-day durability on technical terrain and a carry weight that will not slow you down.
