The 40oz tumbler that actually survives your bag.

TwinLock™ lid locks shut — no spills, no soggy laptop. Keeps drinks cold 24h / hot 9h+. Same size and insulation class as the big brands, at a fraction of the price.

Why people switch to Xurelock

• TwinLock™ leak-proof lid — separate straw + drink-hole locks. Throw it in your bag lid-down. It won't leak. (The bit other 40oz tumblers get wrong.)
• Cold for 24 hours, hot for 9+ — vacuum-insulated double-wall 18/8 stainless. Ice still there at the end of a 12-hour shift.
• Built for real life — durable handle, fits car cup-holders, wide mouth for ice cubes, dishwasher safe.
• 40oz / 1.18L — proper all-day hydration, one fill.

Handle the objections

Is it actually leak-proof or just splash-proof?
Properly leak-proof — the TwinLock lid seals both openings. Tip it upside down in your bag.

How is this different from a Stanley?
Same 40oz format and insulation class — but the locking lid means it survives being knocked over or chucked in a rucksack, at a third of the price.

Dishwasher safe?
Yes. Wide mouth, easy clean.
