Our standard products keep drinks cold for 24 hours and hot for 12 hours. The Pro Series achieves 36 hours cold and 20 hours hot. Results are based on ASTM F2454 standard testing conditions.

Absolutely. All Frostline products use 100% food-grade 18/8 stainless steel for the interior. This grade is the same used in professional kitchens and is BPA-free, BPS-free, and completely non-reactive — meaning no metallic taste and no chemical leaching.

Lids and accessories are dishwasher-safe. We recommend hand-washing the bottles and tumblers to preserve the powder-coat finish for as long as possible, though they will not be damaged by dishwasher cleaning.

The Frost Flask 40oz features our ChillLock airtight lid specifically designed to maintain carbonation. For other Frostline products, we recommend removing carbonation pressure before opening to avoid spillage.

The Pro Series line features aerospace-inspired construction with aircraft-grade 18/8 stainless steel, a ceramic-coated interior for zero metallic taste, a magnetic quick-release lid rated for 50,000+ open/close cycles, and a lifetime warranty. It delivers 36hr cold and 20hr hot retention — the best in our lineup.
