What Is Supima Cotton?

Supima cotton is a superior, extra-long-staple variety of cotton grown exclusively in the United States. Its longer fibers produce a fabric that’s:

• Ultra-soft & smooth – a silkier next-to-skin feel than standard cotton

• Exceptionally durable – resists pilling and holds shape wash after wash

• Highly breathable & moisture-wicking – keeps you cool and fresh

• Vibrant color retention – stays looking new longer

By choosing Supima, you’re investing in underwear that performs like active-wear basics but with the natural comfort of premium cotton.

Designed for All-Day Comfort & Support

The Kirkland Signature boxer briefs feature a modern, supportive fit that strikes the perfect balance between freedom of movement and gentle compression. Key design elements include:

• Contoured pouch for ergonomic support

• Mid-rise waistband that sits comfortably at the hips

• Flatlock seams to minimize chafing and create a smooth silhouette

• 2-inch leg hem that resists ride-up while staying discreet under clothing

This combination ensures you stay comfortable—whether you’re seated at a desk, on a long flight, or working out.

Breathable, Performance-Driven Fabric
