Workout Shorts (With Inner Liner)

Workout shorts with built-in liners have become one of the most popular products in modern activewear manufacturing. They combine comfort, performance, and design flexibility — merging inner compression support with a breathable outer layer that transitions seamlessly from gym to street.

At Athleisure Basics, we specialize in engineering custom workout shorts with liners for global brands seeking European-made, sustainable, and design-flexible production from Portugal. Our approach reflects craftsmanship, ethical sourcing, and a deep understanding of performance fabrics.

Why Inner Liner Shorts Are So Popular

Inner liners add structure and comfort in a single garment, removing the need for separate compression layers. They prevent chafing, enhance mobility, and deliver secure fit with minimal bulk.

• All-day comfort and anti-chafing support
• Moisture-wicking fabrics for extended sessions
• Shape retention and flexible movement
• Minimalist design for training or casual wear

As Miguel Duarte, Production Manager at Athleisure Basics Portugal, explains: “Our clients prefer hybrid shorts with recycled polyester outer shells and mesh liners for breathability and durability.”

According to Euromonitor (2025), Europe’s activewear market is growing at 8.7% annually, with lined shorts now accounting for over 20% of total gymwear demand.

Types of Workout Shorts with Liners

Each type offers a unique combination of support, flexibility, and breathability:

1. Compression-Integrated Shorts

Ideal for HIIT and weight training. They improve circulation, reduce fatigue, and stay close to the skin.

2. Mesh Liner Shorts

Perfect for running or outdoor workouts. The airy liner promotes quick drying and cool airflow.

3. Hybrid Dual-Fabric Shorts

Combine woven outer shells with soft stretch liners for a balance of structure and comfort.

4. Boxer-Style Liner Shorts

Designed for daily wear or light training — offering modesty and relaxed performance.

Fabric Options for Custom Shorts

Portugal’s textile innovation leads the EU in eco and performance fabrics. Common choices include:

• Recycled Polyester: Lightweight, quick-drying, and durable for performance wear.
• Organic Cotton: Breathable and soft — ideal for casual or lifestyle collections.
• Nylon-Spandex Blends: Excellent stretch and resilience for high-intensity workouts.
• Bamboo Jersey: Naturally anti-odor and sustainable, great for premium eco lines.
• Mesh Liners: Provide cooling ventilation and moisture control inside the shorts.

All materials used by Athleisure Basics are OEKO-TEX certified and ethically sourced.
