kytffu 1.66 L (56 oz) Glass Water Bottle with Straw — Blue, Leakproof Borosilicate Jug with Silicone Sleeve & Time Markers

k ytffu 56oz glass water bottle is a large, leakproof drinking jug with a pop-up straw, silicone sleeve, and time markers to help you stay hydrated all day.

This 56-ounce borosilicate glass bottle combines a roomy capacity with a one-touch straw lid, clear time-and-volume markers, and a protective silicone sleeve. Designed for everyday use at the gym, office, or on outdoor adventures, the bottle pairs nonreactive glass with food-grade plastic components so you can sip without odors or unwanted tastes. A convenient lid handle and wide mouth make filling, flavoring, and cleaning easy.

How does the pop-up straw lid make drinking easier?

The lid uses an upgraded one-click mechanism so a single press pops the straw into position and seals tightly when closed. That design reduces spills, keeps dust out, and lets you drink quickly while moving or exercising.

• push-button pop-up straw for single-handed use
• tight sealing mechanism to prevent leaks
• dustproof cap protects the straw between sips
• handle on the lid for carrying or clipping to a bag

Will the glass withstand daily use and temperature changes?

The bottle is made from borosilicate glass, a durable, low-odor material that resists thermal shock better than ordinary glass. It’s suitable for cold beverages, ice, and infused water—just avoid sudden, extreme temperature swings to preserve longevity.

• borosilicate glass resists stains and tastes
• wide mouth fits ice cubes and fruit slices
• food-grade PP straw and lid components, BPA-free
• silicone sleeve cushions the bottle against knocks

How do the time markers and capacity scale help with hydration?

Printed time and volume indicators let you track intake across the day so you can meet personal hydration goals without guessing. With a 56 oz capacity you refill less often, and the visual markers act as an easy checklist during busy schedules.

• clear hourly markers for gradual drinking goals
• capacity labels to measure daily ounces accurately
• suitable for tracking water, infused water, or electrolyte mixes
• large capacity reduces need for frequent refills

How do I clean and protect the bottle for long-term use?

The wide mouth simplifies hand-washing and makes it easy to add ice or citrus. Use the included cup brush and remove the silicone sleeve periodically to clean the glass thoroughly; hand-dry the lid components to preserve the pop-up mechanism.

• wash glass body with the provided brush for best results
• remove silicone sleeve to clean crevices and dry fully
• disassemble straw and lid parts for occasional deep cleaning
• avoid dishwasher exposure for the lid to protect seals

It fits gym bags, office desks, and picnic baskets, and works well for anyone who regularly drinks flavored or iced water and values easier one-handed access without spills.
