Frequently asked questions.

What is Gymshark clothing made of?

Based on our analysis of 1,669 Gymshark products, the average garment is 21.9% natural fibre. The most common single fibre is Elastane (in 71.2% of products). The remaining material is typically synthetic — polyester, polyamide, or acrylic.

Is Gymshark cotton?

Sometimes — cotton appears in 25.9% of the 1,669 Gymshark products we analyzed, but it's usually blended with synthetics. Only 11.9% of items are nearly all-natural (95%+ natural fibre), so check the composition before assuming a piece is pure cotton.

Is Gymshark 100% cotton?

Some pieces are. Of the 1,669 Gymshark products we analyzed, 197 are 100% cotton (or near-pure, 95%+) — that's 11.8% of the catalog. The rest are blends.

How much polyester does Gymshark use?

26.3% of Gymshark products are polyester-heavy, meaning polyester makes up 50% or more of the garment. This is below average for fast fashion retailers.

Is Gymshark mostly synthetic?

26.3% of Gymshark products are polyester-heavy (50%+ polyester). Average natural fibre content is 21.9%, so the rest of the catalog is still leaning synthetic in most cases.

Does Gymshark use natural fabrics?

11.9% of Gymshark products are nearly all-natural (95%+ natural fibre). Only a small fraction of their range avoids synthetic fibres entirely.

Is Gymshark sustainable in terms of fabric?

Fabric composition is one factor in sustainability. With an average of 21.9% natural fibre, Gymshark is below average on this measure. Natural fibres generally biodegrade and shed fewer microplastics than synthetics.

Methodology: We analyzed 1,669 Gymsharkproduct pages, extracting the fabric composition listed by the retailer. Products are categorized by name keywords. Natural fibre percentage is the sum of all natural fibres (cotton, linen, silk, wool, viscose, lyocell, etc.) in each product's composition. Data is refreshed monthly.
