GSI Microlite Vacuum Bottle 1000 Twist

The Microlite Vacuum Bottle 1000 Twist from GSI is a rugged, insulated drinking bottle built for life on the trail. Its one-liter capacity makes it a go-to choice for camping, hiking or any outdoor day trip where you want a reliable way to keep drinks cold.

Made from BPA-free 18/8 stainless steel, this bottle won’t pick up flavors or impart any unwanted tastes. The screw-top “Twist” cap provides a tight seal, and its 12 x 9.1 x 21.1 cm footprint fits comfortably in most backpack pockets or side holders without adding bulk.

Featuring double-wall vacuum insulation, it can maintain cold temperatures for up to 32 hours. The vacuum layer reduces heat transfer through conduction and convection, so your water or beverage stays chilled much longer than in a standard single-wall bottle.
