Keystone Heavy Duty SMS Coverall, CVL-SMS-HE, 25/Case
Keystone Heavy Duty SMS Coverall, CVL-SMS-HE, 25/Case
The Keystone CVL-SMS-HE is a heavy duty SMS coverall built for workers in electronics, medical device, and pharmaceutical manufacturing who need reliable barrier protection without sacrificing comfort or mobility. The three-layer SMS construction — Spunbond-Meltblown-Spunbond — provides a durable particle and fluid barrier that outperforms standard polypropylene coveralls while remaining breathable enough for extended wear. With an attached hood, elastic wrists and ankles, and a zipper front closure, the CVL-SMS-HE is a complete gowning solution in a single garment. Sold in cases of 25, available in sizes Small through 5XL in white or blue.
Industries and Applications
- Electronics and PCB Assembly — contamination control on production lines and ESD-sensitive work areas
- Pharmaceutical and Biotech Manufacturing — particulate barrier protection in ISO-classified cleanrooms and controlled environments
- Medical Device Production — gowning compliance in sterile and semi-sterile processing areas
- Spray Painting and Finishing — fluid and chemical splash protection during coating operations
- Aerospace and Defense — controlled environment assembly requiring full-body coverage
- Food Processing — hygienic barrier garments for production and packaging environments

Frequently Asked Questions
What is SMS material and why is it better than standard polypropylene coveralls?
SMS stands for Spunbond-Meltblown-Spunbond — a three-layer polypropylene construction where the meltblown core provides superior barrier protection against fluids and fine particles, while the outer spunbond layers add strength, durability, and breathability. Standard single-layer polypropylene coveralls lack this meltblown barrier layer, making SMS a significant upgrade for contamination-sensitive environments.
Is the CVL-SMS-HE suitable for ISO-classified cleanrooms?
Yes. The CVL-SMS-HE is commonly used in electronics, medical device, and pharmaceutical manufacturing in ISO-classified environments. Its fluid and particulate barrier properties make it appropriate for cleanrooms and controlled areas where contamination control is required. For the most critical ISO 4–5 environments, verify your specific classification requirements with your quality team.
How does the CVL-SMS-HE compare to Tyvek coveralls?
Both SMS and Tyvek offer particle and fluid barrier protection, but they have different strengths. Tyvek (DuPont's flash-spun polyethylene) is generally more durable for heavy industrial use and offers stronger chemical resistance. SMS coveralls like the CVL-SMS-HE are typically more breathable and comfortable for extended wear, making them the preferred choice for longer shifts in pharmaceutical, electronics, and medical device environments. SMS is also usually more cost-effective per garment for high-volume gowning programs.
Is the CVL-SMS-HE 100% latex free?
Yes — the CVL-SMS-HE is 100% latex free throughout, including all elastic components. This makes it safe for workers and environments with latex sensitivity or latex-free material requirements.
What sizes are available and how many come per case?
The CVL-SMS-HE is available in sizes Small through 5XL to accommodate a full workforce. Each case contains 25 coveralls. Available in white or blue for color-coded gowning programs.
Can I use these coveralls for spray painting or chemical splash environments?
Yes — the CVL-SMS-HE is fluid resistant and provides protection against light liquid splashes, aerosols, and non-hazardous chemical contact. For heavy chemical immersion or exposure to hazardous solvents, a higher-rated chemical protective garment would be required. Always consult the product data sheet and your safety program for specific chemical compatibility.
How do I ensure proper contamination control when gowning with this coverall?
For cleanroom and controlled environment use, gown in a designated gowning area in the correct sequence: coverall over base layer, hood secured, gloves donned last and overlapping the wrist elastic. The elastic wrists and ankles of the CVL-SMS-HE create a close seal at garment edges to minimize particle ingress. Follow your facility's gowning SOP for ISO classification-specific requirements.
