SIGG Design Bottle 1.0L
Here's what other sites are saying:
The 0.6 liter Kaleidoscope is a classic Sigg bottle with a screw top.
It's hard to tell who snagged your last water bottle (it looked like every other bottle on the planet). With the Sigg Design Water Bottle, however, it'll be harder for your office mate to swipe it and claim it as his own. Harder for that girl in your gym Pilates class to 'accidentally' drink out of it, harder for it to disappear into your camp mate's pack, and harder for that dude with the huge, slobbering Newfoundland to 'mistake' your Sigg for the plastic gallon jug he brought to the dog park. The EcoCare liner keeps your beverage tasting like beverage (instead of plastic).
