Dapper guys on the Upper West Side can nab stylish threads without heading downtown, thanks to the opening of this temporary shop. The tiny space is an extension of Efor’s Chelsea location, carrying its namesake menswear line as well as items from Fred Perry, Penguin and JanSport. A concrete floor, white walls and bright lights set the stage for the colorful merch. You’ll find Efor plaid and paisley cotton T-shirts ($105–$135), Penguin polo shirts ($59) and Fred Perry barrel-shaped duffel bags ($80–$100). Limited-edition JanSport ’70s reproduction backpacks ($50–$69), both in solid colors and emblazoned with different countries’ flags, are perfect for spring adventures. Footwear options include Gola canvas sneakers ($68), and Unstitched high-tops ($70) and low-tops ($65) made from recycled materials. Fashion-forward sports fans will love retro-looking Red Jacket T-shirts ($39–$49) featuring baseball, football and hockey team logos.
