Designed for Every Body. Made for Your Brand.
OEM / ODM & Private LabelThe seamless cold chain & freezer collection is S-SHAPER’s dedicated line for cold storage workers, cold chain logistics personnel, and frozen food processing staff.
01 — Collection Overview
The collection includes cold chain base layer tops, cold chain base layer pants, cold chain face masks, and cold chain socks. Seamless warp-knit construction eliminates side seam friction and pressure points during extended wear of heavy insulated gear in low temperatures, while far-infrared heat retention, double-side brushed thermal lock, moisture-wicking, and silver ion antimicrobial meet extreme cold work environments’ demands for warmth, comfort, and durability.
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.
