Hydro Flask Sports Water Bottles Editorial Review
The Hydro Flask with Straw Lid is a popular product that keeps water cold for a long time. The 12 and 24 oz sizes fit in standard car cup holders but the 32-40 oz sizes require a cup holder adapter. The straw is replaceable and washable, and the product is made in China. Some customers had trouble with the straw not working but the issue was resolved by fully extending the straw and checking that it is inserted correctly. There were some concerns over the price of the product and the durability of the bottle, with some customers finding that it dented easily. However, overall, customers found the product to be well-made and great quality.
