The Metallic Gold Squeeze Bottle from Equa is 100% waterproof. The stylish drinking bottle is made of borosilicate glass, which is particularly temperature-resistant and can withstand both hot and cold liquids. The glass bottle gets extra protection from its silicone base, which makes it the ultimate sports accessory. The drinking bottle fits perfectly in the palm of your hand and is therefore comfortable to wear. Myequa drinking bottles can be put in the dishwasher; the lid should be washed separately by hand.
