The Jeffrey Cooler holds 18 cans and ice behind a welded inner seam, so the cold stays put instead of leaking out through a stitched or glued seal the way cheaper coolers do. A PVC-wrapped, PU nylon-coated shell keeps it weatherproof on its own or clipped onto the Basecamp Pad, and a detachable messenger strap makes it just as easy to carry solo. What Our Gearhead(R) Experts Are Saying:"I've packed this full, and pulled the last can out at the end of a full day still cold enough to enjoy. The welded seam is the difference between a cooler that actually holds through a whole afternoon and one that quietly gives up by lunch."
