Ultra lightweight and versatile collapsible water bottles/carriers that are very durable. The 600ml will fit in a typical jacket pocket which is great for short excursions, skiing and boarding. The 600ml and 900ml fits in typical cup holders. The screw on cap with retainer doesn't get lost and provides a better seal than pop up caps. The shock cord loop serves as a safety strap and for a roll up storage retainer.

A drink tube and straw option available and can be used as hydration bladders. Fill 90% and freeze with cap off and toss in a cooler as an ice pack that when melted provides back up water.
