A Bit About The Brand / More Info

The need for Crumpler bags started in the early 90’s when a bloke from Melbourne couldn’t find a bag that let him cycle home with a slab of beer on his back. The pursuit of a solution to this problem eventually saw three mates utilise their creativity to create practical, functional and super durable bags that let you enjoy your trips in style and comfort!
