Is your daily constitutional feeling a bit… pedestrian? Do you look at your leisurely stroll to the pub and think, “This could use a lot more purposeful suffering”? Friend, allow us to introduce you to the GORUCK Basic Rucker, the backpack designed to turn any walk into a low-grade military operation.

This isn’t your flimsy university rucksack. GORUCK has distilled decades of building bombproof gear into this one-task monster: you put a heavy plate inside (up to 30lbs of it), and you walk. That’s it. It’s the perfect fitness regime for the man who finds gyms tedious but wants to feel like he’s training for an undisclosed mission while taking the bins out.

The genius is in the design. The weight sits high and stable on your back, while thick lumbar support and ridiculously comfortable shoulder straps prevent you from whimpering halfway through your “ruck.” There are side pockets for water (or a restorative can of lager), and a reflective strip so cars can spot you grimly marching through the autumn gloom.

For around £115 ($145 USD), you get a bag that’s tougher than a two-quid steak and comes with a Scars Lifetime Guarantee, meaning it will probably outlive your enthusiasm for carrying heavy things for fun. It’s the ideal gift for the man whose fitness goals need a tactical edge. It says, “I support you,” but also, “Please carry the shopping home.”
