Ready Made: The Atom+ VX40L Custom (L) factory 1st

Ready to ship

All our packs are made right here in the Keswick workshop, so we can create custom bags to order (they just take a little longer to build). We’ve designed our bags with the most common use cases in mind, but whether you’re optimising for weight, load or just want a unique colour scheme, the options are yours!

Unfortunately we can’t provide images for every combination of options, and due to the unique nature of the bags, we can’t accept returns on custom packs. 

If you’re looking for something even more specific, then we’ll do our best to accommodate you. Just get in touch.

This is an opportunity to buy a brand new product ready to ship now, at a reduced price.

Every now and again we make an error when we are preparing a customer's order, either we miss something custom in the specification (most common) or we make a sewing mistake (less common) - if we have made a sewing error, it will be photographed and the pack will be labeled as factory 2nd quality.

Ready made sacks are sold as seen, we cannot customise them in any way.

Carbon fibre hoop frame

Removable Hipbelt
The hipbelt measures 3 inches wide. It is made with 10mm laminated foam and includes 20mm webbing and hardware. It can be adjusted by pulling in towards the middle and it is secured in the centre of the belt by 50mm hook and loop tape. The belt can be removed for a 90g weight reduction.

Padded back panel
Uses shaped 8mm closed cell foam. Can be removed when pack is empty for a 15g weight reduction.

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.

Sternum Strap
Elasticated and height adjustable.

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


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.

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

Large front pocket
The Dyneema stretch fabric pocket can hold 5L. It has a diagonal opening.

The Bullet Net front pocket is taller (can hold 10L) and straight across at the top with an adjustable elastic cord for closure. Great for being able to air-dry wet gear and see where everything is!

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


The Atom+

The Atom+

Simple. Lightweight. Durable.

On a long thru-hike your gear, clothing, food and water requirements can all change. The Atom+ is an ultralight pack that can adapt to the conditions of the trail.

Built with

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

Can it fit a Bear Can?

Most bear cans will not fit inside our EP30 packs, but you can rig it on top.

For larger packs (EP40, U40 and above) a BV450 will fit with the base to your back or a BV500 will fit vertically with a little room at the side for a stuffsack.  

How long will it take to make?

Making great things takes time! Our lead time lets you know our estimated production time frame, this will change depending on demand, time of year and staff availability.

The up-to-date lead time can be found at the top of every page on our website and is relevant for all unfulfilled custom orders on our books.

How much does shipping cost?

Shipping rates are calculated at checkout based on your delivery information.

If you live in a remote location, we may occasionally need to charge a small extra surplus for shipping. This will be calculated when we ship the pack.

Customers outside the UK will not be charged the 20% VAT included in almost all of our prices, but you may be subject to local tax and import duties.
