Our Take
The Osprey Transporter Duffel 40 is a 40-litre travel and gym bag aimed at serious gym-goers and weekend travellers who want durability over flash. Built from Osprey's recycled 900D nylon, it sits at the premium end of the gym bag market — priced notably higher than most rivals, but backed by Osprey's All Mighty Guarantee.

Our Verdict
Buy this if you want a gym bag that doubles as a carry-on or weekend bag and you prioritise longevity over features. The lifetime guarantee makes the price easier to justify long-term. Casual gym-goers or anyone wanting wet gear separation should look at more feature-rich alternatives closer to the £40–60 mark.
