Next time you wave goodbye to another water bottle rolling down the ridge, replace it with this. Mad Rock is at it again with an all new design for 2006. We at Mad Rock completely rethought and updated the essential piece in every outdoor lover's arsenal of gear: the humble water bottle. The high-impact, polycarbonate body is slightly squared-off to avoid the dreaded "rollaway," and makes packing and storage a more efficient. The innovative watertight lid allows your carabiner to stay safely clipped in at all times and the lid threads are the industry standard to screw onto any water filter. Finally, a bottle designed for people whose adventures take them out of cell range. 32 oz.
