The zipper on my Ironman wetsuit broke prior to one of the Gatorade swims at Ironman CDA. The Blue Seventy crew swapped my Small/Medium/Tall Ironman wetsuit for a Small/Medium/Tall Blue Seventy Helix. Prior to the swap I tested a Small/Medium Blue Seventy Helix. The Small/Medium fit me much better than the Small/Medium/Tall. Unfortuneately when I returned to do the swap they didn't have the Small/Medium.
