An excellent all-around winter trainer, the Nathan Flurry Waist Pack is a ingenious design to keep your water bottle unfrozen during cross country skiing and winter activity. The Flurry is a low-profile design with an insulated wrap around the water bottle and zippered openings at each end for access. Keep your bottle zippered up during extreme temperatures or unzip one end for easy access. Two zippered waist belt pockets are low-profile and measure 5" by 3" to easily hold keys, gels, corks/kick wax, phones and/or music. Color: blue/grey. Weighs: 10.9 ounces with empty bottle.

One size fits most.
