H. Dessault Technopolymer HD Maxx Plastic Scuba Diving Fins - Lightweight Swim Fins for Snorkeling, Spearfishing & Ocean Adventures

Thanks to the use of a TPE 75 ShA polymer, the energy transmission of the 350 footpocket to the blade is increased, thus obtaining highly efficient fins 

The study of the geometries has allowed us to obtain minimum thicknesses, allowing the weight of the 350 footpocket in size 41/42 to be reduced to just 350 grams 

The reduced mass (weight) of the 350 footpockets, optimizes the use the energy needed for the movement, allowing the diver to save energy and thus reducing muscle fatigue 

To achieve softness, high elastic return and strong breakage resistance, the design and material of the blade are very important features. We have therefore selected and tested a multitude of polymers and we have finally chosen a medium/soft hardness compound suitable for both spearfishing and freediving. This choice guarantees extremely high performance and resistance 

The HD MAXX fins are by far among the lightest fins with long polymer blades. The weight is less than 1300 grams per pair
