If you want the short version:
In my experience manufacturing performance apparel, fabric determines 80% of comfort and durability — design is secondary.
Now let’s break it down properly.
Many people focus on style first.
But in real workouts, fabric affects:
Brands like Nike and Under Armour invest heavily in textile technology because performance starts at fiber level.
From a manufacturer’s perspective, two garments can look identical — but feel completely different depending on GSM, yarn structure, and fiber blend.
Best for: HIIT, running, cardio
Downside: Can feel less premium without blending.
Best for: Strength training, leggings, fitted tops
