If you are looking for something special to transport you water into the field, then you have to buy the SureFire Water Bottle.
SureFire aluminum water bottles, by Liberty® Bottleworks, keep you hydrated while cutting down on the expense and waste associated with bottled water—over 252 bottles are disposed of by the average consumer every year.
BPA-free and made of 100% US-sourced recycled aluminum, these durable, eco-friendly water bottles hold 24 ounces of water or your favorite beverage and feature attractive graphics of two favorite SureFire flashlights: the best-selling Fury® and the technologically sophisticated Invictus®. A looped screw-in plastic lid prevents spillage and makes taking this lightweight bottle anywhere easy by clipping it to your belt or pack loop.
