By Ryan Blake - Tellar Stylist | August 2025

Once reserved for the gym or lazy Sundays, athleisure has evolved into a staple of modern menswear. In 2025 and beyond, it represents the sweet spot between performance and polish—comfort without compromise. Whether you're commuting, travelling, or running errands, the right athleisure look combines freedom of movement with sharp styling.

This guide breaks down what to wear, how to style it, which brands lead the way, and how to ensure your fit is always on point using Tellar.co.uk.

What is Athleisure?

Athleisure is clothing that looks smart and put-together, but feels as comfortable and functional as sportswear. Think tapered joggers that mimic chinos, or stretch-jersey hoodies that layer under a blazer.

Key Athleisure Pieces for 2025

Technical Joggers: Tapered, breathable, often water-resistant with cuffed ankles or clean hems.
Performance Polos: Stretchy and moisture-wicking with a tailored silhouette.
Smart Sweatshirts: Fitted crewnecks in heavy jersey or neoprene blends—minimalist and wearable anywhere.
Hybrid Jackets: A mix of track jacket and casual outerwear—ideal for layering.
Luxury Hoodies: Neutral colours, no logos, often with double zips or scuba fabrics.
