Errant Sling - Open Box, Tan

Boundary Supply Errant Sling — The Urban Commuter’s Weatherproof Sling for Laptop and Cables

The gist: A 15L weatherproof sling with magnetic compression sides, a quick-swing buckle, and a dedicated laptop sleeve for the commuter who needs fast, secure access on the go.

• Dedicated laptop sleeve: 13” Nywool-padded compartment (14” max) keeps your machine cushioned and isolated from cables and accessories.
• Weatherproof zippers: YKK Stormproof hardware seals every pocket — no zip-lock for your cables or rearranging gear before stepping out in the rain.
• Magnetic compression sides: Built-in magnets collapse the bag on lighter carry days, maintaining a sleek, professional profile for client offices and coworking spaces.
• Nywool sunglass pocket & key dock: Dedicated spots for the small essentials that normally vanish into bag pockets during back-to-back meetings.

UrbanCred praised the Errant Sling’s “subtle logos and technical aesthetic” as a “versatile, reliable carry solution” for daily urban use — notable for a sling that doesn’t look out of place in professional environments.

Best for: Remote workers and commuters who want a compact, weatherproof shoulder bag for a laptop and daily essentials without a full backpack. Skip it if: Your laptop is 15” or larger — the sleeve maxes at 14”. Runs ~$152 open-box, ~$289 for the X-Pac version — check the current price before buying.
