UNZIP YOUR POWER
The state of peak performance exists at the intersection of tension and release. Master the "Athletic Sweet Spot" with patented 19 GPa HMF-PEF technology.

The Athletic Sweet Spot
Unzipping to precisely 50% ± 2% is the "Athletic Sweet Spot". It signals your brain to switch from steady rhythm to flow state. Master the balance—you no longer follow the pace; you command it.
Wisdom of Liubai
Inspired by the Daoist principle of "leaving space." 0.5 represents the golden mean—neither fully closed (tension) nor fully open (chaos). This "not-yet-finished" gap is where the most durable energy resides.
Mental Switch Ritual
Pulling the zipper is a psychological anchor. In the dark moments of the "Hitting the Wall" phase, the 0.5 neon mark serves as your spiritual exit, reclaiming your power from exhaustion.
Patented Science
1.6x the strength of traditional PET. Extreme structural integrity at 0.15mm.
Superior to PET (75°C). Maintains V-Shape shape even in extreme humidity.
Zero fiber-core moisture absorption. Prevents 15-25% sweat-induced weight gain.
100% bio-based source derived from HMF. Ethical peak performance.
Material Empowerment
HMF-PEF: Beyond Petroleum
HMF-derived PEF fiber represents a generational leap over petroleum-based PET. Breaking the 0.3mm physical bottleneck, we weave an 0.15–0.25mm fabric with the toughness of silk and the resilience of metal.
This technology translates to "Instant Dryness"—sweat remains on the surface for immediate evaporation, maintaining a constant micro-climate for your core.
Structural Optimization
0.5 Aero-V Stability
Traditional singlets suffer from the "Ear Effect"—collar flapping that increases drag at speed. SPLIT 0.5 leverages 19 GPa stiffness to maintain a sharp, aerodynamic V-Shape even when half-unzipped.
Our patented 50% ± 2% asymmetric ventilation system locks in the optimal airflow, turning a cooling action into a "Wind-Cutting" technical advantage.
Passive Cooling
Gradient Hydrophobic System
Leveraging PEF’s natural hydrophobic barrier, our "Inward-Wicking, Outward-Expelling" structure accelerates evaporation. Heat is removed through latent heat of vaporization, lowering body temperature without the soggy weight.
This is the ultimate solution to the "Wet Weight" pain point, ensuring you feel as light at mile 26 as you did at the start line.
Training Tao
Sustained Equilibrium
The 0.5 Philosophy extends to daily training. High-modulus fiber prevents the shoulder straps from sagging under sweat gravity, maintaining a crisp, V-Shape silhouette.
Whether in the gym or on a recovery run, the 0.5 lock serves as a symbol of self-discipline and sustained peak state—a "Mental Anchor" for the resilient soul.
