With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!


With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

OMM Classic 25 Trail Pack - Grey Information

Season : Sale

Brand : OMM

Code : 80001349

The OMM Classic 25 Running Backpack goes back to basics with an array of storage for all your essential items, comfortable transportation via padded shoulder harnesses and a hydration bladder to refuel you without the need to stop. Your safety is improved thanks to the integrated whistle located on the adjustable chest strap.

With storage and comfort in mind, the OMM Classic 25 Running Backpack is the ideal accessory for optimal performance during intense outdoor activities such as the mountain marathon event. A plethora of pockets allow convenient, accessible storage for all your essential items you may need with you while on the move. Although the backpack can provide large amounts of storage, it is extremely lightweight, meaning any unwanted bulk is eradicated to help improve focus and performance as you strive for the best results. A zipped top pocket is designed for items you need on a more regular basis while two zipped belt pockets add further storage. Mesh bottle pockets securely store your bottles with a hydration tube for instant access to your fuel. The hydration bladder can be routed over or under the shoulder for comfort and practicality.

A speed opening buckle system offers dexterity to save time while on the move when needing to open various access points. When transporting the backpack, EVA padded shoulder harnesses provide comfort and cushioning as well as being breathable to encourage cool air to circulate, and wick away the build-up of excess sweat and moisture. Removable back padding minimises bulk as well as offering comfort while the Duomat works as either a sleeping mat or sit pad to keep you comfortable during the night.

Safety and visibility are significantly improved by reflective details which are ideal for low light conditions when the light is at a premium. An integrated whistle, located in the chest strap further enhances safety as you can grab the attention of a competitor or partner if you find yourself in danger or at risk, especially in the aforementioned lower light conditions. A security key clip in the top of the backpack and waist pocket is ideal for securing your house or car keys so they do not cause distraction or discomfort.
