The 18oz Wide Mouth Hydro Flask is a great mid-size flask that works well across a variety of activities.

Whether you’re in the Arizona summer or the Alaskan winter, Hydro Flask’s 18/8 stainless steel double wall vacuum insulation will keep drinks icy cold for up to 24 hours and hot liquids hot for up to 12 hours.

The wide 2.2” mouth is as easy to pour out as it is to pour in, and the BPA-free, PP#5 flat cap is insulated to further protect your beverage from outside temperatures. Hydro Flask’s 18/8 food-grade stainless steel interior is non-porous and rounded corners help eliminate bacteria buildup, as well as unwanted odors and flavors.

Along with high performing and high quality products, all Hydro Flask products are made from 100% recyclable materials and are backed by our lifetime warranty. Look for the H-guy and Hydro Flask logo to ensure you’re getting the market’s premium insulating beverage bottle.
