Medium grip to squat it like its hot

Use these won’t-budge handles on your shoulders during lower-body moves like squats and lunges

Born on the battlefield.

Built for you.

We’ve taken our military-tested design and brought it to your functional fitness routine. Designed by veterans, our weighted bags make functional training accessible, custom, and ready to go—from the field to your living room.

What will you choose?

Customise your workout. Your way.

Go unfilled to build up your own custom weight using sand, rocks, or even your trusty water bottle. Or prefilled multi-weighted (up to 25kg) ready to roll out and workout the second it’s out of the box.

An absolute game changing bit of kit for me. I spent nearly a year out sorting a physical injury. When I returned I was as heavy as I’d ever been and was genuinely unfit. I invested in the battle bag and haven’t looked back since. 8 months in and I’ve lost nearly a stone, and have packed in muscle and strength. I get bored of gyms but this is a complete gym I can take with me as I travel the country with work. Fantastic product with absolutely outstanding support. Over 35 intelligent complete body work outs and a friendly and knowledgeable community to provide help and advice. I won’t be without mine!
