Hydro Flask Wide Mouth 32 Oz With Flex Cap - 24 Hours Cold

Hydro Flask Wide Mouth 32 Oz With Flex Cap is a stainless steel bottle with a broad opening, a twist-on lid, and vacuum insulation. Its 32-ounce capacity suits extended hydration, while the wide mouth accepts ice and supports filling from outdoor water sources.

Core Specifications

The bottle measures 9.40 inches high, 3.58 inches wide, and 3.58 inches deep, with a listed product weight of 15.68 ounces. The construction uses 18/8 stainless steel, a powder coating, and double-wall TempShield vacuum insulation.

Hydro Flask rates the bottle for up to 24 hours of cold retention and up to 12 hours of heat retention. The lid closes with a twist mechanism, and the bottle is listed as spillproof when closed.

Lid And Compatibility

The Flex Cap uses a flexible strap and stainless steel pivots. The 2.28-inch mouth is sized for ice cubes, and the bottle is compatible with Hydro Flask Wide Mouth caps and lids.

The opening also fits most backcountry water filters. The bottle is BPA-free and dishwasher safe, while the Flex Cap version is intended for hand washing in the specifications listed by PCNA.

Price And Category Context

US listings place the 32-ounce Wide Mouth with Flex Cap at $44.95 as of 09/23/2026. The same retailer lists nearby 32-ounce Wide Mouth configurations in a $44.95-$49.95 range, reflecting different cap and finish combinations.

Compared with smaller insulated bottles, the 32-ounce format carries more liquid but takes more space in a bag. Compared with the Flex Straw Cap version, the Flex Cap favors a simple twist closure rather than a built-in straw, and the official bottle page lists compatibility with the wider Wide Mouth lid system.

Best Fit And Limits

The Hydro Flask Wide Mouth 32 Oz With Flex Cap fits users who want a reusable stainless steel bottle with a large opening, a 32 fl oz capacity, and published hot and cold retention figures. Its dimensions and 15.68-ounce product weight give it a substantial footprint compared with compact bottles.

The Flex Cap is not the right lid for hot-liquid use when the straw-style alternatives are considered, and the bottle is not intended for a stove, microwave, or freezer. Within the insulated bottle category, its defining tradeoff is straightforward: high capacity and a wide accessory ecosystem in exchange for more size than a smaller bottle.
