Deep Apnea S-Glass Mahi Edition Blades


Product Description

All Deep Apnea S-Glass blades are manufactured with 100% S-Glass Fiber. The chemical formulation of S-glass differs from the standard Fiberglass. S-glass is 30% stronger and 15% stiffer and lighter than Fiberglass and retains these properties up to 1500° F. S-glass is also considerably tougher than Fiberglass; there are not comparison between those two in terms of stiffness and performance. When the application is for a Freediving fin the weight is a factor too, S-Glass Fins and lighter than Fiberglass Fins and also the response of the S-Glass Fins compare to the Carbon Fiber ones.

The S-Glass Fins are manufactured following the same formulation proprietary of Deep Apnea has for the Carbon Fiber where the Multilayer disposition of the fibers inside of the core creates a "Variable Parabolic Stiffness" (VPS), resulting in a faster blade response. This delivers a comfortable surface swim and also a strong ascend, with considerable less effort, which in turn saves oxygen during each dive.


The S-Glass Fiber Fins are covered under a warranty period of 2 years and it is a "Limited Warranty". We reserve the right to replace the blade or not after inspection, based on the damage of the fin and the way it was broken, we can determine if the fin was abused or if is a fail in the S-Glass. Any fail in the blade during a normal use is covered under this warranty.
