Traditional performance base layers rely on simple wicking—waiting until you are already drenched to pull liquid sweat away. Our DELTA fabric operates on a microscopic, preventative level.

Custom-engineered exclusively for Kyur, with 37.5® Technology, this fabric functions as a next-to-skin climate-control engine. Thousands of microscopic, mineral-rich active particles are permanently embedded directly into the yarn. These particles act as a smart sensor for your skin's microclimate:

• Passive Warming: When your body is cool, the particles trap your natural infrared (IR) energy to maintain baseline warmth.
• Active Evacuation: The moment you generate heat, the particles weaponize that same IR energy to accelerate evaporation, forcing moisture vapor out of the clothing system before liquid sweat can even form.

By eliminating the humid microclimate that forces the body to waste energy cooling itself down, 37.5® Technology yarns are clinically proven to reduce physical fatigue and increase human stamina by up to 28%*.

• Antimicrobial: DELTA is tested to be 99.9% effective against Staphylococcus aureus (ATCC 6538) and Klebsiella pneumoniae (ATCC 4352)**.

• Odor Resistant: Active particles permanently embedded in the yarn trap odor-causing compounds throughout the day. These trapped elements are then fully released and washed clean during laundering.

Your primary scrub top should never force a compromise between safety and mobility. All Kyur tops are engineered on a highly technical dual-technology hybrid platform, mapping distinct fabric performance zones directly to the physiological and physical demands of the clinician.

• Front-Facing Armor: The front profile of each top is crafted from our CATALYST fabric which meets toxicity and biocompatibility requirements for use in re-usable/multi-use isolation gowns ANSI/AAMI PB70 Level 2*. This front-facing shield prevents blood, bodily fluids, and harsh chemical contaminants to instantly bead up and roll off the surface instead of soaking through to your skin. This fluid-repelling integrity remain effective even after 70+ launderings.
• Structural Resilience: CATALYST has a tear strength that is nearly triple the industry requirement**.
• Rear Ergonomic Engine: The back panel entirely replaces traditional restrictive fabric with our DELTA thermoregulating, ultra-breathable, high-stretch mico-mesh knit. This strategically mapped zone maximizes continuous airflow and unrestricted stretch required for reaching, bending, and high-output physical movement.

A clinician's lower body handles the brunt of mechanical strain—bending, lifting, and sprinting through 12-hour shifts. Our DURATEX pant fabric is an unyielding, tactical armor system built to survive the most punishing clinical environments without restricting natural human biomechanics.

• Proven Pedigree: With a tear strength measuring an unprecedented 82.5psi along the length and 126.6psi across the width*, this exact technical weave is robust enough to be trusted by professional football and baseball teams.
• Unrelenting Stretch & Recovery: Woven from a lightweight and breathable blend Nylon 66 and Spandex. DURATEX unique weave of ultra-high-tenacity Nylon 66 and Spandex ensures flawless four-way stretch and snap-back shape retention with zero risk of fabric fatigue or sagging over time**.
• Elite Repellency: DURATEX is infused with a high-performance DWR (Durable Water Repellent) finish engineered to keep you dry and safe all shift.

Medical environments are notoriously unpredictable, shifting instantly from overheating under intense OR lights to severe overcooling during stationary charting periods. The Kyur ADAPTEX system serves as your auxiliary environmental regulator, delivering intelligent thermal efficiency without adding bulk.

• Micro-Grid Architecture: Constructed from premium, eco-conscious recycled fibers*, ADAPTEX utilizes an innovative, geometric micro-grid channel pattern. This structure forms precise air pathways that vent excess body heat during high-output movement while retaining a soft, plush insulating loft against the skin.
• Heat-Activated Thermoregulation: ADAPTEX features HeiQ Smart Temp™, an intelligent, dynamic finish that responds directly to fluctuations in your skin temperature. When your skin temperature spikes, the system instantly activates to accelerate vapor transport and maximize cooling efficiency by reducing the fabric temperature by 2.5°C (4.5°F).
• Intelligent Deactivation: As your heart rate settles and your body temperature returns to baseline, the system automatically deactivates—slowing down moisture evaporation, retaining body heat.
