We all know how hard it is to travel gluten-free, even when “travel” means just going to the park with a cold one. Splurge on Hydro Flask’s Unbound Series 22L Soft Cooler Pack, a roomy 22-liter cooler that’s easy to carry on your back with backpack straps. Contents stay cold for up to 48 hours. We love the leak-proof design and dry-storage pockets for essentials, like keys and phone. Available in Black, Goldenrod, Storm and Mist.
