Kimberlin Co.


Quality canvas and leather goods, handcrafted in Denver, CO USA.

Winter Session began in 2010 in a storefront apartment in Chicago. Roy Katz and Tanya Fleisher (along with their neighborhood barista and friend, Tristan Coulter, now co-owner of Gaslight Coffee Roasters), began sewing bags and aprons as a way to explore new creative ideas and channel their past experiences in art, design and architecture.

What began as a side project gathered momentum as they forayed into leatherwork, acquired heavier sewing machines, and brought on friends and acquaintances to help with production. — In early 2013, Winter Session left Chicago to establish a new home base in Denver, CO.

Garrison Bag: Grey Waxed Canvas

The Garrison is a heavy-duty carry-all constructed from 20oz waxed cotton canvas. Vegetable tanned leather handles are hand stitched with waxed linen thread and attached with solid brass rivets. Multiple pockets help organize accessories for daily carry and travel. (Mine has become the ultimate puppy day bag. I can carry food, water, travel bowls, toys, leashes, harnesses, paw wipes, clean-up bags, bones and many other useful things to have with two high energy pups.)

Exterior features 

  • Large document pocket with snap closure (easy stash area for a leash)
  • Two end pockets (can fit a water bottle and also a dog fetch toy)
  • Accessory pocket (I keep a sketch book and my waxed canvas roll-up in here)
  • Leather tab closure with brass stud (such a handy feature!)
  • Detachable leather shoulder strap with solid brass buckle (I almost always leave this on.)

Interior features

  • Accessory pocket (clean-up bags, bones and treats)
  • Small document pocket (fits iPad)

Zip Bags are simple and versatile pouches for organizing your essentials on the go. Sized to carry pens and pencils, small notebooks, chargers and cords, toiletries or small accessories. Made from sturdy 20 oz waxed cotton canvas, each bag features a solid brass YKK zipper with imprinted leather zipper pull.  (I use mine to carry spoon rings and patches around so I can photograph them!)
