When selecting warehouse clothing, durability and safety are paramount. You must prioritize high-denier fabrics (e.g., 300D-600D Oxford polyester) for abrasion resistance. Ensure the use of reinforced triple-stitching at high-stress points like crotches and armpits. For cold storage environments, verify the GSM (Grams per Square Meter) of insulation, typically requiring 200-400 GSM for sub-zero temperatures. Additionally, look for moisture-wicking linings to maintain worker comfort during high-intensity shifts.
