Fit with Confidence – And Consciousness
At Pima Prima® we want you to feel great in your T-shirt. That’s why we offer returns if you're not fully satisfied with your size. But we’re also here to address a bigger issue: the environmental impact of returns and long-distance logistics.

Every return shipped across borders contributes to unnecessary carbon emissions and packaging waste. Our goal is to reduce this burden by helping you choose the right size the first time — through clear measurements, detailed guidance and personalized support.

The problem we’re solving:
Traditional fashion returns create up to 15 million metric tons of CO₂ emissions annually and generate tons of landfill waste. We're working to minimize that footprint — not by eliminating returns, but by making them smarter, fewer, and more sustainable.

Heavy weight vs Medium weight vs Light weight ELS Pima Cotton. All you need to know.

Ever wondered why some Pima cotton t-shirts feel thick and structured while others are soft and stretchy? The secret lies in textile techniques—specifically, the difference between Gamusa and Jersey weaves. Understanding these differences is essential if you care about fabric quality, sustainability and how your clothes perform over time. At Pima Prima, we use these techniques to create premium ELS Pima cotton t-shirts that last longer, feel luxurious and support ethical and sustainable fashion practices.

Gamusa: The Double-Faced Weave (Heavy Weight)

Gamusa is woven using a tight and structured pattern, making it identical on both sides. This creates a thicker, smoother and more durable fabric ideal for winter t-shirts and structured garments.

  • Feels like: Cashmere-like softness with a dense and warm texture
  • Best for: Winter Pima cotton t-shirts, sweaters and layering pieces

Why you’ll love it:

  • Durability – Holds shape over time and resists stretching
  • Warmth – Keeps you comfortable in cooler weather
  • Reversible – Looks the same on both sides making it versatile

How it’s made:

  • Tightly woven with denser yarns for a solid structure
  • Fabric undergoes a softening treatment to enhance its luxurious feel
  • The result is a double-faced Pima cotton fabric that lasts longer and keeps you cozy
  • For more about Gamusa weaving techniques, visit TextileSchool on Double-Faced Weaves.

Jersey: The Single-Face Knit (Medium and Light Weight)

Jersey is knitted rather than woven making it soft, stretchy and breathable. Unlike Gamusa, it has a smooth front and a looped back which affects its texture and drape.

  • Feels like: Lightweight, airy and flexible
  • Best for: Everyday Pima cotton t-shirts, dresses and activewear

Why you’ll love it:

  • Breathability – Keeps you cool in warm weather
  • Stretch and Comfort – Moves with your body for a relaxed fit
  • Soft Draping – Flows naturally making it ideal for casual wear

How it’s made:

  • Yarn is looped together in a single-face knit creating a soft texture
  • The looser structure gives flexibility and natural stretch

The result is a one-sided Pima cotton fabric that feels smooth on the front and slightly textured on the back
