AtomPacks is a relatively new British company: 4 years old at the time of writing this. Tom and his team hand make the packs to order, so they can be made in a standard configuration or customised and made to measure for your back length. The Prospector model is very lightweight, starting from 650g depending on the size and extras added.

About 3 years ago I had a 60-litre bespoke AtomPacks Prospector rucksack made with waterproof fabric, side pockets, roll-top entry, front mesh pocket, top and side compression straps. sternum strap, ice axe loop, shoulder strap pockets, bottom pocket, load lifters and removable hip belt pockets.

Note the custom extra loops for bungee cord to hold the roll mat

My Prospector weighs 1050g, which is very light weight for its size. The standard 60L pack would be lighter but mine has all the extras: 2 Hip belt pockets, 2 Shoulder strap pockets, Base pocket and Tom fitted some custom extras for me: 2 elastic straps on the shoulder straps to hold cloves, etc and 4 loops on the pack base to put bungee cord through to hold a roll mat.

Frame with 2 alloy stays and the removable foam

The back frame has a plastic frame sheet and two alloy rods. It’s well padded and successfully transfers weight to the hip belt. It’s also easily removable if needed.

Shoulder straps and Hip Belt optional pockets

I particularly like the mesh pocket on the front of the pack. It’s large enough to hold a complete one person light weight tent, or even a two person flysheet. This is ideal for stowing it away wet so it stops the rest of my gear inside my pack getting soaked. It also means that I can setup and break camp without opening my pack. This is particularly useful when it’s raining, as I can pack or unpack my rucksack inside the tent. Storing the tent on the outside of the pack, also makes it quick and easy accessing it for drying it during a lunch break etc. The pocket could also be used to store a lot of odds and ends, or spare clothes that may be needed during the day, if it’s not needed for the tent.

Hip belt pocket and optional bottom pocket

The optional hip belt pockets are accessed with a zip that runs across the top and are roomy enough to hold snacks, gloves, etc.

The shoulder strap pockets are the perfect size to store a mobile phone or 350ml drink bottles. But unfortunately not my new waterproof the Ulefone Armor 3W rugged smart phone. Note the custom extra elastic loops under these pockets to hold gloves etc.

A useful bottom pocket can be accessed whilst wearing the pack, and I find it perfect for tucking in maps and gloves.

The side pockets are made of a fairly tough non stretchy material, which is good because I find this area gets a lot of abuse while pushing through over grown paths etc. They will easily fit a 1 litre water bottle in with room to spare. My MSR Guardian water purifier pump just fits in one side and I often balance that, by carrying a tent in the other side, using the bungee cords to hold it in place.

The TGO Challenge

I use the bungee cords on the side of the pack to store my waterproofs, and sit mat, which then gives me easy access to them without having to open the main pack.

The Prospector is very well constructed with a tough, waterproof fabric which looks great. The seems are not taped so the pack is not fully waterproof; however, there are very few seams to let water in. I would always use dry bags inside my pack anyway, so the untaped seams aren’t a problem for me.

Used as a very comfortable day pack with my family

Because the pack is so light weight I have used it as a day pack on occasion, and it works really well.

I used my Prospector for a month-long trip on the TGO Challenge coast-to-coast across Scotland, and a number of other hikes including the Austrian Alps. I was easily able to carry a week’s food and all my camping gear and found the pack comfortable up to about 15kgs. Above this weight, I got slight shoulder pain after long periods carrying the pack.


I feel that the AtomPacks Prospector is a very good rucksack, especially as you can have it made exactly how you want it. It is made with quality materials and should last well.

I think the rucksack was good value for money. But as they are made to order, delivery could be a while depending on AtomPacks’ workload. Mine took nearly 2 months to arrive, but it was well worth the wait.
