Issued to Gridline couriers operating across all weather conditions in GLMZ's layered urban environment, this weathershell jacket does the heavy lifting of keeping drivers functional during twelve-hour shifts in rain, industrial particulate, and temperature swings across the city's climate-uneven districts. The outer shell is a seam-sealed ripstop with a hydrophobic coating that sheds water and light chemical spray. GPS antenna filaments are woven into the left sleeve, feeding route data directly to a wrist-mounted display or BCI interface. High-visibility orange panels at the shoulders and lower back are retroreflective. A rear hem vent accommodates tail modifications. The Gridline logo and courier ID number are printed on the back in weatherproof ink that remains scannable after heavy wear.
