A first mug for the Lightweight line
Both models come in Atlas Blue and Cypress Green, with matching colors across the vessel and lid. The 12 oz mug holds 354 ml, weighs 262 g and measures 90 × 110 mm. It costs ¥6,490 including tax.
The mug combines a stainless-steel body with a closeable polypropylene lid and slider. Hydro Flask rates it for up to 24 hours cold or 6 hours hot, but its product page does not describe the lid as leakproof and says to keep the mug upright inside a bag.
The 32 oz bottle changes wall thickness
The 32 oz Flex Chug Cap bottle holds 946 ml, weighs 375 g and measures 80 × 280 mm. Its double-wall body tapers from thinner steel near the top to thicker steel toward the base, while the cap uses a honeycomb insulation structure, perforated carry strap and aluminum pivot.
Hydro Flask says the bottle is about 25% lighter than its standard 32 oz model and rates it for up to 24 hours cold or 6 hours hot. A Morse-code H2O pattern distinguishes the bottle from the matching mug. It costs ¥8,690 including tax and is limited to Hydro Flask's Japanese direct stores and official online shop.
