Why are training shorts a key direction in men's activewear collections?

 Training shorts are a key direction because small structural choices can strongly affect comfort, function, and sample approval. Inseam length, liner or linerless construction, waistband support, drawcord, phone pocket, zip pocket, shell fabric, stretch, and anti-chafe seam placement all change how the product performs. For private label brands, reviewing these details early helps avoid developing a generic short that does not match the target training scenario.
