If you like a fin that feels locked-in and powerful—especially in current, in a drysuit, or while using technical kick styles—the X1 BladeFin is made for you. Atomic Aquatics designed the X1 around a Monocoque structure and Power Plate to create a solid internal frame that channels your leg and foot power into real thrust, not wasted flex.

Unlike long, floppy blades that can “fold” under load, the X1 uses a shorter, stiffer blade and rigid low-profile side rails to make turning, pivoting, and helicopter-style maneuvering smoother—without fighting side drag. The asymmetrical blade bend improves feel on the return stroke, which is exactly where frog kicks, scissor kicks, and tight-circle turns demand control.

For comfort and ease, the X1 includes Atomic’s patented EZ-LOK buckle system, designed for confident on/off and simple strap adjustment. It also features a taller foot pocket with a low-friction entry, making it a strong choice for large boots and drysuit boots.

Key Features (bullet list)

Firmer, shorter paddle blade for “raw thrust” and strong propulsion

Rigid, low-profile side rails to reduce side resistance and improve pivots/turns

Monocoque Structure + Power Plate for efficient power transfer and solid control

Asymmetrical blade bend flexing for better alternate-kick performance without folding

Vertical stabilizers/strakes for straight tracking with lower drag

EZ-LOK Buckle System (patented) for easy, secure buckle release/reattachment

Taller foot pocket suited for larger/drysuit boots

“paddle fins for frog kick”

“tech diving fins for helicopter turns”

“open heel scuba fins for drysuit boots”

“stiff blade fins for current” (matches the X1’s design intent)
