No less than three SwearBy fashionistas don this glamazonian option. “Backpacks are a must for me; I show up for every business meeting with one,” says Katia Pryce. “I especially love this neoprene one because the fabric keeps clean from sweat and New York air. I haven’t used it in the summer yet, but I’m sure it would be great after breaking a sweat in the heat. This is my go to bag for going from the gym to the conference room.” Margaret Flores uses it as her go-to travel bag. “It’s super durable, holds everything I need (lots of pockets) and I get a ton of compliments,” she says. But Sarah Holdeman has the best reasoning for tossing this over her shoulders: “Because it’s cool.”
