The Tempercraft Sport bottles are the best double-wall, vacuum-insulated, stainless steel hydration bottles that we have ever used. They keep beverages cold for 24 hours and hot for 12 hours. Grab one today and see what a difference it can make on hot summer fairways. These bottles have a laser-etched TriFly strAtus logo on them.
Excellent sports bottle holds cold fluids more than a day, have yet to try hot fluids yet I am guessing will have same results. Will recommend to all my friends
