I'm a yogi- a teacher and a student. 
I like to keep it simple- one bag to house the essentials (wallet/keys/phone) - and a few of those extras (yoga mat, water bottle, towel, snack, notebook, eos..). So I desiged this bag with that in mind.
 
Fits a standard 24" width yoga mat.
Can house a chunky or larger mat, or a regular mat with a towel and water bottle- see 'the extras' above.
Crystal zipper-pull.
Handmade in Muskoka from a combination of new and upcycled fabrics.
