• Recycled Fabric: The main body is 100% recycled polyester 600d fabric that is bluesign approved, reducing environmental impact without sacrificing durability.
• Durable Exterior: Water-resistant and abrasion-resistant coating stands up to daily wear and wipes clean easily if the bag gets dirty.

Who It's For

This insulated lunch cooler suits commuters, office workers and outdoor recreation users who need a compact but capable bag to keep lunches cool and contained. It is a good fit for men and women who prefer a low-profile, stylish bag that pairs easily with daily gear and does not add much weight.

Those who need heavy long-duration refrigeration for extended day trips, large group outings, or to hold multiple full-size bottles should look for a larger hard-sided cooler; this 8 L bag is designed for single-person daily lunches rather than multi-day food storage.
