Diesel Diamond Razorback

The Diesel Diamond Razorback Racerback Tank is built for high repetition use whether worn by athletes, retail staff, or event volunteers. Constructed from the Sport‑Tek LST356 PosiCharge Competitor system, the garment uses engineered synthetics to pull sweat away from the skin and inhibit odor buildup between washes. The technical racerback silhouette removes material from under the arms and across the shoulder blades, eliminating chafing during squats or overhead reaching while preserving a sleek profile that layers cleanly over sports bras or base layers.

Because performance apparel fits differently than casual tees, selecting the correct chest measurement prevents excess fabric from shifting during movement. Compare your current tape measurement against the standardized range below to lock in a secure, non restrictive drape:

• XS: 32–34 inches
• S: 35–36 inches
• M: 37–38 inches
• L: 39–41 inches
• XL: 42–44 inches
• 2XL: 45–47 inches
• 3XL: 48–51 inches
• 4XL: 52–55 inches

This expanded size continuum supports everything from solo replacements to uniform fleets without requiring custom alterations. Since the fabric relies on moisture managing polymers rather than natural fibers, machine washing in cold water and skipping the dryer maintains elasticity and keeps seams intact for months of heavy rotation. Match your chest width to the chart above to guarantee reliable coverage, uninterrupted range of motion, and consistent appearance day after day.
