With it's wide base, smooth rake, and medium sized tip, the Colab 2 goes well in all types of surf. We have had a chance over the past 8 months to test this template, and make subtle changes to suit everyone looking for a high performance fin. Featuring the current "tail art" on all Chemistry boards by Collective artist Pace. This fin is a med/large fin with a 4.65" base and 4.73" height." Honeycomb interior.
