A Fjällräven vardag duffel 30
This premium outdoor brand has a newly released lightweight bag in its product range. Constructed from the brand's special water-resistant fabric, it's also great from an eco-perspective, as it's made from 65 per cent recycled polyester and 35 per cent organic cotton. This bag is definitely strong, and you'll be able to squeeze it into a tight space without worrying about damaging it.

B Filson medium rugged twill duffel bag
This brand has a great tradition of producing simply the best quality gear. If you're inclined to treat yourself to a bag that should last you a lifetime, this is for you. Admittedly it's likely you'll need to save up for this one, but it's well worth it.

C Deuter trans alpine pro 28
This pack has got so many features, which does, however, make it on the heavier side. For example, the pouch at the back is expandable to put your bike helmet (or trainers / towel / other sizeable gear) in, and the side pockets are perfect for water bottles.

D Columbia unisex convey 25l rolltop daypack
The full-width zip means you can easily push stuff in. There's one main compartment which also has a separate padded sleeve for a tablet plus an extra zip pocket for valuables at the top and convenient metal rings to attach items like bike helmets if required.

E The North Face base camp duffel
This top-of-the-range bag has a very generous 50 litre storage capacity. If that's too much for you, there's always the trimmer 31 litre equivalent (which retails a little cheaper). There's an internal pocket to separate some gear out and an extra small external zip pocket on one of the ends.

F Under Armour sports style duffel
A simple yet effective and stylish bag. At 24 litres it's neat in size, and a separate smaller waterproof compartment at one of the ends is ideal for putting damp gear in so that everything else is unaffected by it. It also comes with a removable strap so you can wear it over one shoulder. It's a decent option for an everyday gym bag that won't break the bank.
