[Product Overview]
FITFLEX Hybrid Knee Sleeve is a premium lower-body training support system developed through five years of dedicated R&D focused specifically on the mechanics of the knee joint. Unlike products that simply adapt elbow-sleeve specifications, FITFLEX created an independent knee-specific structure with optimized materials, compression, and support for squats, machine training, and high-intensity lower-body workouts.
[3-Stage Hybrid Support]
The system combines a base sleeve with two detachable support straps. The Base Sleeve provides comfortable compression and warmth for warm-ups and general training. The BASIC Strap offers flexible tension for machine work and high-repetition routines, while the POWER Strap provides firmer compression and structural support for heavier free-weight movements.
[Advanced Knee-Specific Design]
The support strap features a dual-sided structure: a friction-enhancing inner weave helps reduce slipping against the sleeve, while the embossed outer weave supports even compression around the knee. A silicone-free dual-x-layer sleeve combines a soft nylon inner surface with a high-tension polyester exterior for comfort and stability.
[Adjustable & Functional Details]
A polygonal multi-angle attachment zone allows users to adjust compression direction, while split ergonomic Velcro follows lower-body movement naturally. Creora® Fresh functional fibers support moisture management and freshness, and clear BASIC/POWER and Left/Right indicators improve usability.
[Made in Korea]
More than 90% of raw materials are sourced in Korea, with the entire manufacturing and quality-control process completed domestically. The hybrid system is officially design-registered with the Korean Intellectual Property Office (KIPO).
