Collaborative Collection: Gym Master and Blue Blue Unveils Pocket T-Shirts and Zip Parkas

Collaborative Collection: Gym Master and Blue Blue

The prominent athletic wear brand Gym Master, established in 1916 in Nova Scotia, Canada, has collaborated once again with the Blue Blue brand for the third time in 2026. Known for its high-quality sweat items that blend functionality with a classic aesthetic, Gym Master continues to highlight durability in its products. The partnership with Blue Blue, initiated in the fall/winter 2024 season, emphasizes “tough, everyday clothing” — a philosophy that resonates with both brands.

This season features a collection crafted from a unique 7.2oz dry waffle material, which combines cotton and polyester. This innovative fabric not only offers a distinctive texture on the outside but also a flat, smooth finish on the inside, making it comfortable against the skin. Designed for high absorption and quick-drying properties, these garments are perfect for the warm late summer season.

The collection includes two distinct pieces: a pocket crew-neck T-shirt and a zip parka, both designed with raglan sleeves for enhanced movement and comfort. The T-shirt features an embroidered logo from Blue Blue on the chest pocket and a tag from Gym Master on the ribbed cuffs. Additionally, both brands’ names appear on the back, adding a collaborative flair that is thoughtfully integrated into the design, showcasing the identity of each brand.

By amalgamating Gym Master’s longstanding commitment to durability with Blue Blue’s dedication to quality daily wear and heavy-duty designs, this series aims to deliver practical clothing that transcends trends for everyday use.
