Hazard 4 Plan-B 17L Hazard Go-Bag Thermo-Cap Sling Backpack – Black, 2017 Edition

If you’re after a compact, no-nonsense sling backpack that’s built to take a bit of rough and tumble, the Hazard 4 Plan-B is right up your street. With a handy 17-litre capacity, it’s slim enough to wedge into those tricky spots – think between car seats or tucked away in a locker – perfect when space’s tight but you still need to carry your essentials.

Designed for quick grabs on the go

What really sets this pack apart is the way it swings from your back to your front without having to take it off completely. Need something in a flash? Just swivel it round, grab what you need, and crack on. Plus, it’s ambidextrous, so whether you’re right- or left-handed, you can set it up just how you like it.

Rugged, weather-ready build

The front features a thermoformed semi-rigid cap that shields your gear, complete with MOLLE cutouts on a soft loop patch – ideal for clipping on extra pouches or patches if that’s your thing. It’s crafted from tough Invista 1000D Cordura® fabric (or 500D Cordura® for the camo versions), both treated with a double PU water-repellent finish. So when the British weather throws a dampener on your plans, your kit stays nicely protected.

Comfort and clever functionality

On the back, you’ve got a thermoformed pad designed to keep the airflow going, which makes a world of difference when you’re on the move and the temperature rises. It even supports hydration bladder access and holster attachments, making it equally at home on a hike, a daily commute, or just out and about. Inside, a padded divider and stabiliser strap keep your gear snug, tidy, and easy to find.

Who’s this one for?

Ideal for blokes who need a reliable, compact sling pack that won’t hold them back. Whether you’re setting off on a day hike, want a go-bag that’s ready for anything, or need a tactical-style backpack that’s practical for city life, this pack ticks all the boxes. It’s especially handy if you’re often juggling kit and need quick access without faffing around.

The lowdown

The Hazard 4 Plan-B sling backpack strikes a smart balance between tactical features and everyday ease. It’s tough, weather-resistant, and designed to keep your gear organised and within arm’s reach. If you’re after a versatile pack that can keep up with whatever your day throws at you, this one’s definitely worth a gander.
