Gymshark is performance activewear built almost entirely from synthetic fibre. Across the Gymshark styles read to the Throne Standard, only 4.9% are 100% plant fibre (cotton, linen or hemp). 28.0% are plant and synthetic blends, and 67.1% are 100% synthetic, the range leaning heavily on nylon, polyester and elastane.

These figures come from the 88.8% of Gymshark’s 1,834-product catalogue that has been read. The remaining 206 products (11.2%) publish no fibre composition anywhere we can read, so they are counted in the catalogue total but sit outside the percentages above. Every one of them is listed in full below, with the excluded non-textile items, so you can check them yourself.
