Simplicity is key for Jason Gregory's collection of stylishly masculine bags. His new line MAKR is completely handcrafted in North America of the finest leathers and toughest industrial woven fabrics. The MAKR holiday pop-up shop is housed inside Hayes Valley's most exciting addition, Acrimony. and Gregory will be debuting brand new, previously unreleased items (think: totes, duffle bags, wallets, and cardholders). The elegantly hand-sewn items will be in the store through Januar—so holiday gifts are in the bag.
