Workwear Anatomy

Designed to Outlast
Standard Cotton Tees.

Most casual t-shirts are made from 4.0 oz to 4.5 oz carded cotton that shrinks, twists, and loses shape after just three washes. The Carhartt K87 is engineered from heavy 6.75 oz ringspun cotton jersey to ensure it keeps its shape and outlasts generic shirts by years.

Reinforced Bartacks

The chest utility pocket is reinforced with precise stitching to prevent tears under weight load.

Side-Seam Construction

Reduces twisting of the torso over time, maintaining a square drape wash after wash.

Crewneck Collar Shape Retention

Rib-knit collar stands up to stretch and wash cycles, preventing the classic "bacon collar" sag.

Standard Tee

Generic Casual Shirts

  • 4.0 oz lightweight fabric wears out and tears quickly
