What is Lifetime warranty?

A lifetime warranty is a written promise that covers a product for as long as you own it, rather than for a fixed period. It tells you how a brand expects its gear to hold up, and it can cut the cost of replacing a failed item. In practice, most brands in this group stop at a limited guarantee. Altra does not offer one, and neither do AktivWinter, All Ball Pro, Alphard Golf or Arc'teryx. Expect a standard warranty period instead, and read what it excludes before you buy.
