MORE DURABLE THAN EVER

With the Hero 2.0, we looked to create a bag that was as strong as you are.

With the Pro Series, we took that one step further.

Using 1000D military spec fabric the Pro Series Backpack has been manufactured with every eventuality in mind - whatever the day or workout requires, we guarantee it won’t be your bag that lets you down.

That’s why we’ve introduced a FREE 2-year warranty.

SECURITY UP TO SPEC, FOR YOUR TECH

We spent time to create a new and improved laptop compartment within the exterior shell of the back pack.

Located inside the Pro Series exo skeleton, the laptop sleeve provides 360 degree anti shock cushioning to ensure that your most valuable possession is kept safe.

With side access, you can now keep your laptop separate to the rest of your gym essentials, food, clothing and shoes - making it easier than ever to work on the go

Compression Straps

For the Pro Series Backpack, we’ve introduced an infinity-strap system across the entirety of the bag.

Using these, you’ll never again have to deal with the loose ends of your straps dangling by your side.

Each and every strap loops back in on itself, and along the base of the bag, we’ve even included a retracted strap sleeve so you can keep them fully out of the way whilst you’re on the move

A SPACE FOR EVERYTHING

It’s not always ideal to throw your entire wardrobe into one 45L compartment.

That’s why we’ve added in a dedicated and fully ventilated shoe compartment at the base of the Pro Series Backpack - so whatever the weather or conditions you’re working out in, storing your shoes wont be an issue

GO PRO

We've always been best in class in capacity. And that hasn't changed.

Introducing the Pro Series - the most technical bag we've ever built. Made with the elite athlete in mind, the Pro Series was built to take our 45L capacity and optimise it for the everyday athlete, any day of the week.
