DL Tandem Dual Thermo - Battery - Pulsar

Thermochromic Series has a special coating on the outside for a mesmerizing color-changing effect. Enjoy this model anywhere --even while hiking a trail or riding along on bumpy roads-- thanks to the silicone mouthpiece, which prevents that uncomfortable clacking of accidental mouthpiece-against-tooth action. This piece is also removable for hassle-free cleaning, magnetically attaching back on top for a sturdy connection.
