How does the Blueseventy Fusion compare to its competitors in the market, and what sets it apart from other wetsuits? Is the added buoyancy and flexibility provided by the Fusions proprietary technology worth the additional cost, or do other wetsuits offer similar performance at a lower price point? Some argue that the Fusions design prioritizes speed over comfort, but is this a fair assessment, and how do the experiences of triathletes and open water swimmers compare in terms of overall satisfaction with the suit? Additionally, what role does the Fusions fit play in its overall performance, and how does the suits sizing compare to other wetsuits on the market? Do the benefits of the Fusions unique design outweigh any potential drawbacks, such as limited flexibility in the shoulders or a less-than-ideal fit for certain body types? How does the Fusions durability and lifespan compare to other wetsuits, and is the added expense of the suit justified by its potential to outlast cheaper alternatives? Are there any notable differences in performance between the Fusion and other high-end wetsuits, or is the market for top-of-the-line wetsuits relatively homogeneous in terms of performance?
