The Mo 

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 930g/31.4oz, The Mo won't weigh you down. 

We have recently updated the pack to now include two shoulder pockets and a bottom pocket as standard.

4 inch wide Dual adjustable hipbelt
Comes with 4 adjusters that tighten by pulling inwards allowing you to dial in the perfect fit. 

Lumbar pad
Made with 10mm EVA foam and 3mm thick spacer mesh.

Plastic Frame with removable Alloy stay
Removable frame sheet made of 1mm thick plastic with a sewn-in 12mm / ½" alloy bar. The frame for a medium torso length weighs 91g of plastic, and 58g of alloy.

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

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

Roll top closure 
The closure has a 15mm vertical side compression. The roll top can also be clipped together at the top (dry bag style) and the side compression clipped around the front of the bag to aid carrying snowshoes or maybe a huge packs of chips etc.

Z side elastics
Great for securing trekking poles, tent poles or drying your socks.

Dual shoulder pockets
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.

Hydration tube port

There is an access port behind each shoulder strap, allowing access inside the bag where there is a hanging clip for your bladder.

Bottom pocket
Easy-access bottom pocket with trash port made with Dyneema stretch fabric.

Large front pocket
Made with Dyneema stretch fabric. Can hold 5L, not included in the total volume.

Side pockets
Two 2.5L forward-facing, deep and low side pockets made with 210D Robic Extreema. Each one is big enough to keep 2 x 1L Smartwater bottles steady, yet low enough to reach whilst the pack is worn.

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

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

Sternum Strap
Elasticated and height adjustable.

Ice Axe loop
Sewn-in loop to easily connect an ice axe or walking poles.

Over the moon

I've only been hiking seriously for a couple of years and looking at my 1st long-distance this summer. I bought the Royal Red MO 60 5 months ago and I'm so delighted with it. There are so many ultralight options out in North America, with even the big guys revamping their lines to meet the trend. I really wanted something unique (a quirk of mine; I stay away from the big names), cottage industry, and wanted to invest in people's lives. It turns out that ATOM is not only fully customizable, but very competitive compared to ZPACS, Hyperlite, and so many others because there's NO middle man. I feel I've invested in a family. They've also had super follow-up with me, answering any question I had, no matter how small. THANKS! For Toronto, Canada.
