Description

The Prospector (previously known as The Mo)

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

We designed The Prospector 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 Continental Divide or Te Araroa then The Prospector is for you!

With a load capacity of 19kg/42lbs and pack weights starting at just 910g/32oz for a size Medium, The Prospector won't weigh you down.

Features

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.

Sternum Strap
Elasticated and height adjustable.

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

Great service, great product

Having being a pack I’ve had on my radar for a while I contacted the team and they happily had my and my pup (coffee) into the office to do a fit check while showing me around. The staff were super polite and welcoming while accommodating my dog as I was out camping for a few nights.

They got my pack and measurements spot on while making sure the pack sorted my needs perfectly.

After owning the pack a while I can happily say it’s my all year pack, I can easily get my hilliberg soulo, Rab accent 1100 and all my winter gear in the 50L prospector with spare room.

The pack is extremely comfy and having the adjustable back support that moulds to how your back is makes such a difference.

Definitely worth my time and it’s amazing to support the team while getting a pack that will last me a long time.

Awesome

Just received my Prospector. I ordered it from Ireland at 0900 when a batch dropped on Tuesday, paid customs taxes on Wednesday and received the pack Thursday afternoon. Compared to my custom 40L Pulse it has considerably more volume. The Pulse has dyneema side pockets and is fine for shorter trips but not quite big enough for multi day trips for me. I am delighted with the Prospector. The quality of these packs is superb.

Puzzled

Used it twice now for wild camps carrying about 10kgs , First time I used it the chest harness catch came off , later found in my mates van , very kindly sent me the previous models strap out which are totally better , puzzled about the straps on the hip belt , as I can only see one strap with a catch on , for the two straps , thought there would have been two separate catches ,

Having used the Atom Packs Mo EP50, now known as the Prospector, for the last three months, I've found it to be an exceptional companion for multi-day hikes and wild camping. The pack scores high on comfort, thanks to its ergonomic design that distributes weight evenly, reducing strain during long treks. It's well crafted with durable materials that withstand rugged terrains, ensuring longevity and reliability. The thoughtful proportioning allows for ample storage without compromising mobility. Overall, Atom Packs delivers a product that excels in both function and form, making it a worthwhile investment for avid adventurers seeking quality and comfort. I have no reservation in recommending this product at all, it is by far the best pack I have owned and will be using it more over the winter months to test it even further.

Backed up by the support from Tom Dexter and the team with invaluable personal customer experience its a worthwhile investment

Awesome Pack

I love this pack, it’s simple and functional made from quality products and put together skill fully. The bottom pocket is really useful for my Tyvec ground sheet and storing my rubbish so I leave no trace
