Ibex has been designed to be a lightweight beast of burden. Big enough to gobble up your rack, ropes, helmet, harness, extra layers, a sausage roll, and camping equipment, yet light and trim enough for you to stomp up a snow encrusted Scottish gully.

Designed and made in the UK with rock solid construction, uncompromising and durable materials, and attention to detail that can only come from hours of lugging kit around the hills and spending nights under the stars.

A quick glance around the outside of the pack reveals the simple and thoughtful add-ons that make your Ibex so adaptable, such as its four side compression straps, stabilising straps, hydration port, removable ice axe loops, and bungee cords. 

For extra streamlining, Ibex can be fully stripped back to make a minimal and lightweight sack: take off the lid, straps, waist belt and back stiffener and it weighs in at 795 grams.

The removable back stiffener has a central alloy strut that can be moulded to your back profile when your sack is loaded up for a big adventure.

The main compartment is constructed from VX21, a technical fabric commonly used as sail cloth, it has great strength to weight properties. The base is made of 500D Cordura for a balance of abrasion resistance and weight. The main compartment can be extended for extra capacity and cinched closed with the drawcords. The drawcord sleeve is reinforced for added durability - talk about attention to detail! A compression strap over the top provides an attachment point for a coiled rope, waterproof, or fleece.

The removable lid has a large main compartment with a zipped valuables pocket on the underside.

Ibex is available in two back lengths because people have different length backs and, if you are climbing you may want to wear it higher up your back for mobility.

Made in the UK and made to last. All the contact points are bar-tacked, seams are double-stitched, load-bearing straps are sewn into the seams. Ibex comes with our 25 year Alpine Bond warranty.

Fitting guidance: To select the correct back length measure from the top of your hip bone to the top of your shoulder. This should place the waist belt over the middle of your hip bone and provide the most comfort for carrying loads. Select a shorter back length if you prefer to wear your rucksack higher up your back, when climbing for example.
