Hydro Flask 64 oz Wide Mouth vs GEDUX 64 oz Insulated Water Bottle

Buy the Hydro Flask if you want a proven half-gallon bottle with a strong warranty and a huge accessory ecosystem. Buy the GEDUX if you want a two-mode lid (straw and chug) and included straws and brush for less commitment. Both hold 64 oz of 18/8 stainless steel with double-wall vacuum insulation rated cold 24 hours and hot 12. The Hydro Flask has a longer track record and a leakproof Flex Cap; the GEDUX adds lid flexibility but is hand-wash only per its spec sheet, despite the listing mentioning dishwasher safe.

• Choose the Hydro Flask 64 oz Wide Mouth if you want the established brand, a leakproof cap, dishwasher-safe cleaning and broad accessory support.
• Choose the GEDUX 64 oz if you want a straw-or-chug lid, spare straws and a cleaning brush in the box.
