Mammut Boulder Chalk Bag

Bought it for around £23 which is really a bargain for a new quality chalk bucket.
The design is really great, the bucket is not as big as some others ones from Snap etc but it is still considered the bucket.
I love the way it folds and closes, making it impossible for the chalk to get out - I am happy with it.

It has propper side pockets for my keys, and phone and a little placeholder for a brush.

Really nice bucket - get it !
