Frequently asked questions.

What is Alo Yoga clothing made of?

Based on our analysis of 475 Alo Yoga products, the average garment is 34% natural fibre. The most common single fibre is Elastane (in 67.8% of products). The remaining material is typically synthetic — polyester, polyamide, or acrylic.

Is Alo Yoga cotton?

Sometimes — cotton appears in 19.2% of the 475 Alo Yoga products we analyzed, but it's usually blended with synthetics. Only 19.4% of items are nearly all-natural (95%+ natural fibre), so check the composition before assuming a piece is pure cotton.

Is Alo Yoga 100% cotton?

Some pieces are. Of the 475 Alo Yoga products we analyzed, 26 are 100% cotton (or near-pure, 95%+) — that's 5.5% of the catalog. The rest are blends.

How much polyester does Alo Yoga use?

33.7% of Alo Yoga products are polyester-heavy, meaning polyester makes up 50% or more of the garment. This is above average for fast fashion retailers.

Is Alo Yoga mostly synthetic?

33.7% of Alo Yoga products are polyester-heavy (50%+ polyester). Average natural fibre content is 34%, so the rest of the catalog is still leaning synthetic in most cases.

Does Alo Yoga use natural fabrics?

19.4% of Alo Yoga products are nearly all-natural (95%+ natural fibre). Only a small fraction of their range avoids synthetic fibres entirely.

Is Alo Yoga sustainable in terms of fabric?

Fabric composition is one factor in sustainability. With an average of 34% natural fibre, Alo Yoga is below average on this measure. Natural fibres generally biodegrade and shed fewer microplastics than synthetics.

Methodology: We analyzed 475 Alo Yogaproduct 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.
