Rennen Recycled Crossbody Sling 2.5L, Blue

Boundary Supply Rennen Crossbody Sling 2.5L — Lightweight Day-Tripper Built From Recycled Fabric

The gist: A 2.5L sling that weighs just 0.6 lbs, hits the essentials-only sweet spot for urban exploring and day trips, and is made from 55% recycled materials.

• Featherlight at 0.6 lbs: Compact 10″×5.5″×3″ footprint and RE-3™ Cordura Eco fabric keep the bag itself from being the burden — ideal when you’re already carrying a camera or a main pack.
• YKK AquaGuard® zippers: Water-resistant zippers protect a passport, phone, and essentials during sudden rain — no rain cover needed for light showers.
• Organized main compartment: Key clip loop, internal stash pockets, and a zippered interior pocket separate small valuables without fumbling; padded back sleeve protects a phone.
• Exterior lash loops: Attach a jacket, light tripod, or other trail accessories to the outside — useful when you need hands-free carry on active walks.

Boundary Supply describes the Rennen as built from RE-3™ recycled materials including Cordura® Eco fabric — a practical choice for eco-conscious travelers who don’t want to sacrifice durability for sustainability credentials.

Best for: Day-trippers and urban explorers who want a lightweight, water-resistant sling for a phone, wallet, passport, and keys when leaving the main pack at the hotel. Skip it if: You need more than 2.5L — this is a minimalist grab bag, not a half-day hiking sling. Runs around $23–$59 depending on sale — check the current price before buying.
