If your office allows shorts from April through October, you already know the difference between a pair that rides up on porch steps and sags by mile three versus one that doesn't. These don't.
 
Flying Cross 5 oz texturized woven polyester — light enough to breathe in July, heavy enough to hold its shape and keep the permanent crease after six washes. 9-inch inseam hits just above the knee, which is the regulation length and looks right with a uniform shirt tucked in.
 
Built into these:
• 5 oz 100% texturized woven polyester, heather postal blue
• Permanent leg creases, factory set
• Double-lined front pockets — reinforced where your keys and scanner ride
• French fly closure, bar-tacked belt loops
• 9-inch inseam (USPS regulation)
• Plain waistband, fits standard 1.25" or 1.75" postal belt
 
Fit: True to waist. Machine wash, hang dry if you can — low tumble is fine but the crease stays sharper on the line.
 
USPS compliant. Uniform allowance eligible.
