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 pole or tent stakes when stored in the side pocket. If you are wanting to compress the bag, we recommend switching to a non-stretch cord.

Customer Reviews
I have just taken my atom +40 to Everest base camp and back having used it for 6 months as a day training sack. Brilliant. Super light and really easy to use. I bought it ready made so it came with a thick removable waste belt and no shoulder pockets which I added as accessories. Most of the time the waste belt isn’t needed because the shoulder straps are so good. Definitely better to have sewn in shoulder strap pockets as the add on ones move about a bit. Sternum closing clip could be a bit larger for my liking. Sometimes a bit fiddly to close when fully loaded. But so much better than what everyone else was carrying in every day. Never noticed it on my back.
My first Atom Pack. I bought this pack 2 months ago to help reduce my spring/summer pack weight and have been nothing but blown away by the detail and thought of the design. Currently in the process of purchasing a custom MO60 for winter and i know ill be impressed yet again. Added bonus to be able to support another great UK maker. Thank you Atom Packs
I received a 40l Atom+ for my birthday - the all robic fabric one.
I used it for the first time on my 12 day crossing of Scotland in this year’s TGOC.
I didn’t notice the weight (9kg) at all until day 11! No sore shoulders!!
The pocket underneath the sac for food is brilliant.
An amazingly comfortable sack that is just big enough for all I need for a long trip.
I’m really impressed with the quality materials, fittings and impeccable UK manufacturing. The pack has the perfect balance of simplicity and yet equipped with considered and well thought out features - it’s a very well accomplished design. Atom were great to deal with and the various YouTube videos gave a great insight into their ethos, I’m happy to wear their pack with pride.
My standard Atom 35 in VX21 came in at 450g, but removing some of the optional bungees that I know I won’t need should see it down to ~425g which is hugely impressive given it’s capabilities.
Keep up the good work, I wish Atom every success.
Thank you.
Too many of the other ultralight products I've purchased recently just haven't been durable enough to justify buying and using. I've used the 35L atom on many trips now and it's blowing everything else out of the water. It's been in the desert, swamp, and mountains and it's my favorite piece of gear.
The wide shoulder straps are not noticeable until you go back to a pack that has smaller ones. Then you will miss the wider straps. The pack itself is pretty narrow; narrower than I thought it would be, but it can still fit the smaller, blue bear canister in any orientation. The bottom pocket works well too.
I can get 5 days of food comfortably in the 35L, 6 if I am diligent. I love the pack for any trips less than a week. Anything longer would probably start to get a little uncomfortable.
