The Watersy narrow-mouth sports bottle is a double-wall vacuum-insulated flask with a cola-style shoulder and a narrow drinking mouth closed by a stainless-steel-top screw cap whose internal plug carries a silicone sealing ring, advertised as "100% LEAK PROOF". The wall is built in five layers: an 18/8 stainless steel liner, an electrolytic process layer, a vacuum insulation layer, a stainless steel outer layer and a wear-resistant powder coat layer, giving hot and cold retention ("KEEP HOT & KEEP COLD"), the retail box repeats "DOUBLE LAYER VACUUM INSULATION", "100% SEALED AND LEAK PROOF" and "100% STAINLESS STEEL" with COLD/HOT icons. Two sizes are offered, 17oz/500ml (22.2cm tall, 251±10g) and 12oz/350ml (18cm tall, 207±10g), both 6.9cm in diameter. Ten powder-coated finishes are shown, six of them two-tone gradients (light pink-red, light blue-light pink, light blue-dark blue, dark blue-black, purple-blue, green-blue) and four solids (light pink, light blue, purple, black), each with the WATERSY logo on the lower body. Marketing scenes position it for car, yoga, motion, riding, camping, beach and hiking use, including bike-bottle-cage, car cup-holder, campsite and poolside shots. Dimensions are manual measurements and may vary slightly per the source note.
