The shoulder-season sweater. Too warm for the bomber liner, too cold for just the long sleeve — this is what you throw on over the shirt in October and again in April. Flat-knit construction lays clean under a jacket without bunching at the waist or pilling at the elbows after a week.
 
Specs:
 
• 100% PIL-TROL acrylic — resists pilling, which is why the old wool-blend sweaters got retired
• Flat knit construction, lays smooth under outerwear
• Full-length front zipper, crew neck collar
• Two lower hand pockets
• Embroidered USPS eagle, left chest
• Machine wash cold, lay flat or tumble low
• Regulation navy blue
Fit: Runs slightly loose by design so you can layer a long sleeve under it. If you don't plan to layer, size down. The 'Regular' weight is lighter than the Bulky — if you run northern routes in hard winters, the Bulky (ASA 5100) is probably the better call.
 
USPS approved. Uniform allowance eligible.
