Our take on the Sea to Summit Horizon Insulated Mug 475 ml

The Sea to Summit Horizon is a 475 ml insulated travel mug built from polypropylene and fiberglass, with a polyester-lined lid. It is designed for campers and commuters who want a mug that stacks, seals and survives a dishwasher. At about 4.1 oz it is light for an insulated mug, though the plastic build trades heat retention for weight. Owners like the leak-proof lid and stackability; some find it keeps drinks warm for shorter stretches than steel rivals.
