Meso is Stokely Discs’ translucent premium plastic, the clear, durable blend of the range. Four moulds are listed in it, from the Finch putter to the Lark and Robin fairway drivers.
Clear premium plastic is bought to hold flight: it resists wear, so a Meso driver stays close to its printed numbers longer than a baseline one would. Meso Soft is the same plastic in a softer, more flexible mix, so far offered only on the Finch.
The usual trade applies. Clear premium blends are slicker in the wet and stiffer in the cold, and Thermo is the Stokely plastic for grip.
