The #1 teacher recommended mat mindfully made for a lifetime of flow. In a world that produces much more than it needs, we try to reduce waste whenever possible. Our Almost Perfect PRO mats may have a few flaws… but they still have a life to live! Still 100% performance focused, but they are “cosmetically unique.” Almost perfect mats may differ in the following ways: May differ slightly in length, thickness and weight May have surface imperfections May have nicks on the bottom side May differ slightly in color/logo May have variations in cut, i.e. may be cut askew While the Lifetime Guarantee doesn't apply to "Almost Perfect" PRO-mats, we know they will last (and you will love them) for many years to come!
