The Hydrapeak Food Jar is constructed with food-grade stainless steel and double-wall vacuum insulation that will keep food hot for 10 hours and cold for 16. The leakproof lid will keep your soup, salad, and other meals inside without any spills. Easily grab and open when you’re ready to eat with the folding carry handle. The sweat-free exterior removes any condensation and keeps the inside of lunchboxes and other bags dry.
