Cool Garments

CoolTech™ scrubs

More comfortable than disposable or cotton scrubs, CoolTech™ wicks moisture away from the body and dries quickly. Tight weave and an anti-static grid provide optimal protection. Scrubs are embedded with a thin anti-theft wire (for use with UniTech’s Garment Sentry™ system) preventing them from leaving the facility. Long sleeve shirt, short sleeve shirt, and long pants are all available in sizes Small-4XL.

ProTech Plus® coveralls

For everyday comfort and minimized heat stress, choose ProTech Plus coveralls. EPRI’s “Guidelines for the Optimization of Protective Clothing – Heat Stress and Skin Contamination Protection” awarded ProTech coveralls a desirable ZERO Heat Stress Index adjustment factor (WBGT). Available in sizes Medium-6XL.
