Streamlined ultralight for day trips and overnights
The Bummer distils Trail Bum's philosophy into a 30-litre package that's big enough for overnights but light enough that you'll barely notice it's there. Like the Steady, it features a simple cylindrical roll-top design with an expandable section, sized for people who've gutted their kit down to the bare necessities. The construction uses ripstop nylon fabric made with Spectra fibre for premium versions, offering exceptional strength-to-weight ratios. The back now features a removable pad for enhanced lightweight comfort, whilst mesh pockets on the front and sides handle the usual quick-access items. Side pocket bases have been reinforced for improved durability. At 30 litres, it hits the sweet spot for fast and light trips where you've got your base weight dialled in and don't need excess capacity tempting you to bring things you won't use.

If you’re the kind of hiker who measures pack weight in grams rather than kilos, who knows their base weight down to the last stuff sack, and who's figured out that carrying less means walking further, Trail Bum is built for you.
Created by Japanese ultralight pioneer Tomoya Tsuchiya – owner of cult Tokyo outdoor store Hiker's Depot – this is his backpacking philosophy distilled into packs that strip away everything unnecessary. The brand name says it all: these are bags for people who'd rather spend time on the trail than living in the city, designed with the streamlined simplicity that reflects that lifestyle. No excess features, no unnecessary weight, just functional gear that lets you focus on the path ahead.
Tsuchiya introduced ultralight hiking in Japan when it was still considered radical, opening his store in 2008 and championing the idea that reducing your load isn't about being lightly equipped – it's about distilling kit down to essentials through cutting-edge design. Every Trail Bum pack embodies that philosophy, built from advanced composite materials like ALUULA, Spectra fibre and Ultra 200X that offer exceptional strength-to-weight ratios.
Whether you're planning mega thru-hikes, wild camping getaways, or just reconsidering how much you actually need to carry, Trail Bum represents the evolution of what a backpack can be when you stop adding features and instead start asking what you can take away.
