When you are ready to crack a cold one, Engles HD-30 Soft-Sided Cooler won't disappoint.With ice-keeping ability of up to 4 1/2 days in 90-degree heat, this soft-sided cooler gets er done with a rugged, waterproof, virtually air-tight design. What separates the HD-30 from its competitors are the seams, all of which are welded to make them waterproof, air-tight—and far superior to the leaky, sewn seams of many others. The welded seams are complemented by the waterproof, air resistant zipper that does not require lubrication for optimum function.What else make this cooler great Let's start with patent-pending vacuum valve technology which enables users to suck out the excess air (with a vacuum) to push the outer boundaries of ice-keeping performance. Other features include an outer shell made of tough 840 denier fibers that maximize strength and abrasion resistance. Strength and puncture resistance are further enhanced in the front and back sides which are laminated with a Thermal Plastic Urethane (TPU) film. Closed cell foam insulation walls out warm air and ensures that your libations remain cold and ready to refresh.Getting this cooler out to your car or down the dock is easy. You can carry it like a tote or sling it on your shoulder with the padded strap. Appointments also include an attached bottle opener and a water-tight storage compartment for your cell phone or personal items.Key Features32-quart capacityKeeps ice 4 1/2 days in 90 degree heatAir- and water-tight welded seamsAir-resistant zipper requires no lubricationRugged 840 denier shellFront and back laminated with a Thermal Plastic Urethane (TPU) filmClosed cell foam insulationVacuum valve technology boosts performanceWater-tight storage compartmentAttached bottle opener
