The Atom
Aimed squarely at the ultralight hiker, the Atom gives you easy access to everything you need to keep hiking all day long using the five pockets that are easily accessible when worn.
This pack has few load assisting features and, as such, is only intended to be used by those with dialled in gear lists who like to enjoy the freedom of a light pack and moving without a frame or hip belt.
Weight from 408g / 14.4oz (size M)
Load capacity 9kg / 20lbs max
Features
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.
Sternum strap
Elasticated and height adjustable.
Ice Axe loop
Removable loop to easily connect an ice axe or walking poles.
That's it. This pack is for serious UL users only.
Customise
Shoulder pockets:
Super stretchy and big enough to hold even the biggest smartphones, a day’s worth of snacks or a 700ml water bottle. We offer these in sewn in or removable options.
Our preferred choice is for sewn in as standard
Front zig-zag elastic
Removable and designed to be able to store a folded Z-rest or assist with air drying your clothes.
Side Compression options:
- Elastic: These are there to secure a trekking pole or tent poles when stored in the side pocket, also a handy place to dry socks
- Webbing: If you are carrying anything heavy in the side pocket, these are a slightly stronger option than elastic and have much greater compression strength

EcoPak EPX200
Durable and lightweight, EPX200 is a recycled 200 denier face fabric with eco DWR finish, blue 45 degree cross ply and white recycled 70 denier backing fabric.
The EPX200 is our choice for The Atom+ due to its eco credentials, waterproof qualities, light weight and added durability.
Not too shabby on the eye either.
Good to know

Genuinely cannot recommend Atom packs enough 😍 You can really tell the difference between a fast-tracked factory line big brand bag, and the Atompack bag I got which was handcrafted with care and time. Quick shout out to Rachel in the customer care team who reassured me and put up with me when I was panicking about the timeline and my upcoming trips 🙈😅 I've had the backpack a few months now, it was a custom build with all the trimmings and awesome colours. I went to Washington State and completed the Three Fingers Lookout over 3 days, along with a trip to the Grand Canyon. So the backpack got dredged through rain, cold, high winds, rocks and wet, then complete opposite - scorching sun, dust and sand. I used it for everyday walks, and also filled it to the brim with overnight camping gear for hikes. Each time it was used there were no issues and the bag feels so sturdy, BUT SO LIGHT it's crazy. It was checked onto the plane as hold luggage and survived that as well!! The price point is amazing considering the length of time I know I will get out of this pack. It's so versatile I'll be able to attack any adventure or day-to-day task with ease. This is one of the easiest recommendations I've ever made. When it comes to gear as important as a bag, you really need to get it right first time. Do it right, do it once. That's my motto! Much love, Hannah Banana :) x
This backpack is fantastic. It's clear that every detail is meticulously looked after by Atom Packs. The fact you can customize and the lengths to which you can go with the customization is astounding. I highly recommend the Dyneema stretch pockets, a bottom pocket, and a Y Strap for the top. I used this pack for a thru-hike of the Haute Randonnée Pyrénéenne (HRP) and could not have been happier with the pack's performance. Even carrying far beyond the recommended load, I never once worried about my pack's performance. It still looks as good as new, and I've seen zero deterioration in the pack's materials or stitching. Do yourself a favor and order your custom pack now to get ahead of the one potential downside to this pack, which is the lead time; your future self will thank you.
I bought this backpack in 2021 and is still my favorite pack hands down. Before I purchase this pack I had gone through three other cheaper packs from different company's and was tired of not be happy with the cheaper made packs that didn't check all the boxes I wanted. I was at the point in my hiking journey that I willing to spend a bit more money for better quality that will last longer and is also lightweight. I came across this Atom backpack company not sure about purchasing a pack from a company Ive never heard of before. I did some research before the purchase and this one checked all the boxes. Like I said Ive had this backpack for a few years and its seen its far share of adventures. A few Colorado 14ers and 200+ miles on the Appalachian trail. It still looks good as new, no rips or tears. Its lightweight and strong design cant be beat.
If your looking for a great lightweight pack what will last a long time with great features look no more:) Happy Hiking!
This is a great pack, it kind of becomes with your back. Very light and comfortable with lots of space for all your stuff
I did extensive research into ultralight packs from all over the world before finding Atom Packs in my own backyard.
I didn't have time to wait for a custom pack so I ordered a limited edition Atom which looked pretty much how I would have customised anyway. It had a wait time of four weeks but arrived in two.
I was immediately impressed by the quality of the build and attention to detail but waited to write this review until I had done a two week through hike with it. Home now and it performed to perfection and still looks brand new. I bought the optional padded belt as I knew I would be carrying pretty much to capacity every day and it was sooo comfortable.
I love all the details on this pack; the asymetric back pocket, the strap pockets which are just the right size for a phone or snack, the bottom pocket which is just right for a map or guide book and the fact that the chest strap is adjustable so you can get it just right.
Overall an amazing pack for a very resonable price.
