KitBrix: tough kit bags for triathlon, swimming, running and the gym

Shopping at KitBrix? See all current KitBrix discount codes and deals, checked regularly.

KitBrix makes bags for people whose sports kit tends to end up muddy, wet or scattered across a changing room floor. The company dates back to 2013, and its signature product is the Hero Bag: a 20-litre, box-shaped holdall with a waterproof base, mesh outer pockets and smaller inner pockets for keys and electronics. Two bags can be zipped together and carried as a rucksack, which is handy on race days.

The bags come with a strap that can be fitted in several positions and slot-in icons for the outside pocket. Clubs can order team icons, and the FAQ says there's no minimum order for standard bags. The base is waterproof and the rest of the bag is highly water resistant, but because the zips interlink KitBrix doesn't call the whole bag waterproof.

It suits triathletes, swimmers, runners and gym-goers, as well as parents juggling children's kit for several sports. The range now includes totes, a backpack, dry bags, change mats and activity bundles, and many items use recycled ripstop fabric.
