The LARQ Swig Top 1000 ml insulated stainless steel water bottle is a wide-mouth, water-filtering bottle designed to deliver cleaner, better-tasting water. Its included filter enhances water quality through a 2-stage filtration and purification process. The insulated stainless steel body keeps drinks at the desired temperature for up to 24 hours, while the wide opening makes it easy to fill and clean. The cap features a built-in, detachable soft-touch handle for convenient carrying. Filters should be replaced regularly for optimal performance.
