Long-sleeve T-shirts differ in more than colour. This category includes regular shirts, turtlenecks and fabrics ranging from cotton to recycled-fibre blends and nylon. Choosing a neckline and fit first helps narrow down the styles.
Compare each model's fibre composition and weight, cuff design and stated stretch. Details such as recycled content and care requirements belong to individual garments and should not be assumed across the whole category.

Turtleneck or regular long sleeve?
The Promodoro 3407 is a close-fitting turtleneck with elastane in the collar and cuffs. It uses 100% combed cotton in a 220 g/m² interlock fabric. It offers a different neckline from a conventional long-sleeve tee.
The Promodoro 4099 Premium has a more relaxed fit and uses 100% combed cotton in 180 g/m² single jersey. It features narrow ribbed cuffs with elastane, a tubular construction without side seams and reinforced shoulder seams. Both the fit and fabric differ from the 3407 turtleneck.
Fabric and wearing differences
Pure Waste LSMB contains 60% recycled cotton and 40% recycled polyester at 190 g/m². Onna NN370 and NN270 specify a base composition of 50% nylon and 50% recycled nylon, with a jacquard pattern and four-way stretch. These are distinct fabrics with different intended features.
For a team selection, compare fit, stated size range and cuff design. Fabric blends may also vary across certain colours. Explore the wider T-shirt category for additional styles to combine.
