We love this super trendy Green Fanny Pack by Bonheur Du Jour.
It's not only pretty but also ultra-practical and fully adjustable with a buckle. It can be worn at the waist or on the shoulder, on foot or by bike!Snap flap and zipper under the flap for added security. 
An ideal size for storing keys, smartphone, wallet...you'll be surprised how much you can fit inside! 

Dimensions: width 26 cm x height 18 cm.
