Contact Gear Kidney Bottle

For starters, if you filled this traditional 1quart canteen with your Dad's favourite tipple, you'd be seeing pink elephants by the herd. Made from impact-resistant, BPA free Tritan copolyester (apparently this is important - just ask some students) this canteen resists long-lasting tastes and odours. Which is just as well if it's used in an emergency and there's no portaloo handy. That said, it fits standard issue canteen cups. Not school canteen cups, they're hopeless. A list of benefits you can rattle off to your mates, if there's absolutely nothing else to talk about are below:

• BPA free – again, students know all about this.
• Impact resistant – in case, you drop it. Or fall over.
• Dishwasher safe - not like you care, but someone else will need to know.
• Capacity: 1qt (945mL) – no hip flask, this baby.
• Material: BPA free Tritan copolyester – see first point above.
• Temperature Range: -40°C to 100°C – perfect for Mars.
