Black Diamond Blades (Allure Collection)

Days to Ship (DTS) : 14 days

BLADE:

The Sireniana freediving blade is made of a specially formulated mixture of epoxy resin and 100% carbon fiber, processed thermally and under pressure. There is a balance between power and energy efficiency to achieve the ideal flexion curve. In doing so, less muscle effort is required for kicking, from either ship or shore, surface swimming or deep dives.

SHAPE:

The Sireniana blade shape is designed for instant responsiveness and also to be aesthetically pleasing. The blade is 83.0 cm long and 19.8 cm wide with a 22° inclination relative to the foot pocket. The length of the blade is slightly longer and slimmer in comparison with most freediving fins on the market and hence gives it a more elegant look. Our signature smooth curved whale-tail shape tip is designed to prevent blade slippage to the side and gives a more powerful thrust while kicking.

DESIGN:

Black Diamond Limited Edition - The eye-catching ‘Allure Collection’ was created to enhance the elegance that Sireniana is devoted to,  providing customers with more options when it comes to visual appeal and appreciation. The Allure Collection blades come with a highly reflective mirror-like gloss finish which is sleek and luminous and makes the colour more vibrant. The beautifully designed images were embedded directly into the carbon fiber blade and sealed under an extra layer of protective clear coating. This protects the artwork from accidental scratches. More designs will be presented and introduced in the near future. 

STIFFNESS:

Our blades are available in soft, medium or hard stiffness, and our general recommendation is soft blades for freedivers with a bodyweight under 55kg, medium blades for 55kg~80kg,  and hard blades for freedivers whose weight is over 80kg. 

RAIL:

Freediving fin rails increase the performance of your fins by channeling water down the blade, also by protecting the blade and extending its life. Our fin rails also feature a three-dimensional hydrodynamic variable height design which prevents water from spilling out on the sides, optimising the channel thrust to ensure the best efficiency.

We stand behind our products and warrants the product against defects in materials and workmanship for a period of one year from the time your item is shipped to you.
