Designed for Every Body. Made for Your Brand.
OEM / ODM & Private LabelThe seamless underground utility inspection & municipal repair collection is S-SHAPER’s dedicated line for sewer maintenance workers, underground utility inspectors, municipal repair crews, and cable tunnel patrol staff.
01 — Collection Overview
The collection includes underground work base layer tops, underground work base layer pants, underground work knee supports, and underground work socks. Seamless warp-knit construction eliminates side seam friction and pressure points during extended confined space work, wet conditions, kneeling repairs, and protective gear wear, while abrasion and scratch resistant yarns, quick-dry drainage, optional water-repellent finish, far-infrared thermal warmth (constant underground low temperature), silver ion antimicrobial, and high-visibility design meet underground municipal work demands for durability, protection, and all-day comfort.
Our 800,000-piece monthly capacity is supported by 50 advanced seamless knitting machines and automated production systems, alongside 200+ industrial sewing machines. With approximately ten effective production months annually after planned holiday and maintenance periods, each seamless machine produces around 16,000 garments per month. This production structure ensures stable supply, consistent quality, and dependable delivery for large-scale industrial, performance, and professional apparel programs.
