Get ready for your next adventure

It took us 12,000 miles of hiking to design our perfect backpack: The Mo – a lightweight, fully-featured load hauler, purpose built to support you on your next adventure.

We designed The Mo to suit the average thru hiker using modern, lightweight gear, with a base weight of up to 10kg/22lbs. We use lightweight, durable materials that are easily able to cope with heavier loads and heavier use. If you are heading out onto rough and overgrown trails like the CDT or Te Araroa, then the Mo is for you!

With a load capacity of 19kg/42lbs and pack weights starting at just 890g/32oz, The Mo won't weigh you down.

Weight From 890g / 31.4oz (40L, size M)

Load capacity 19kg / 42lb


Packing Space

Main Pack body
The main body of the pack is completely open, yours to fill as you wish. It is secured with a roll top closure that can be secured vertically for added compression or dry bag style.

Large front pocket
The front pocket can be sewn in either Dyneema Stretch material or Bullet Net, both offer capacious storage. The Dyneema Stretch is better for a cleaner aesthetic and off trail bushwacks (doesn't snag easily) and the Bullet net is better for packing wet gear and improved visibility of items but can snag when bushwacking. The bullet net option will increase the measurable volume of your bag by 5L.

Side pockets
Each pocket can hold 2.5L and are perfectly shaped to carry 2 x 1L smart water style bottles with ease. You can use the elastic drawcord to secure these items whilst walking and, should the elastic ever break or wear out, we have designed it to be easily replaceable.

Load Carrying

S-shaped shoulder straps
Sewn using 10mm foam, durable 210d Robic Extreema face fabric and breathable, soft 3mm spacer mesh

Padded back panel
Uses shaped 8mm closed cell foam. Can be removed when the pack is empty for a 25g weight reduction.

Plastic Frame with removable Alloy stay

Add More

Shoulder pockets (optional)
Super stretchy and big enough to hold most smartphones, a day’s worth of snacks or a 700ml water bottle. The elastic is fixed and, owing to its clever design, does not need a tensioner.

Removable and designed to be able to store a folded Z-rest or assist with air drying your clothes.

Side elastic with Lineloc (optional)
These are there to secure a trekking pole or tent poles when stored in the side pocket..
