Quick answer: rPET stands for recycled polyethylene terephthalate. It is a synthetic fabric made from post-consumer plastic bottles that have been cleaned, shredded and spun into polyester fibre. Every Will and Wind towel is made from GRS 4.0 certified rPET microfibre. Each beach towel contains the equivalent of 16 recycled plastic bottles: a verified figure, not a marketing estimate. |
If you have spent more than five minutes reading about sustainable textiles, you have seen the letters rPET somewhere. On product pages, on certification badges and in brand sustainability sections. It usually gets presented as self-evidently good without much explanation of what it actually is or why some rPET claims are worth more than others.
So. Here is the honest plain-English version of what is rPET, how a plastic bottle becomes a beach towel and what the difference is between a certified claim and a brand just saying a thing.
What rPET Actually Stands For
Recycled polyethylene terephthalate. PET is the plastic used for water bottles, soft drink bottles and food packaging. It is one of the most widely produced and also one of the most recyclable plastics in the world. The r at the front means the PET has been through a recycling process rather than being made from new petroleum.
Short version: your old plastic bottle, given a second life as a beach towel. Specifically, 16 of your old plastic bottles per Will and Wind beach towel.
How a Plastic Bottle Becomes a Beach Towel
The process is not magic but it is genuinely interesting. Collected PET bottles are sorted, cleaned and shredded into small flakes. Those flakes are melted down and pushed through fine spinnerets into polyester fibre. The fibre is then spun into yarn and the yarn is woven into fabric.
The specific form in Will and Wind products is microfibre specifically. Defined by the extreme fineness of the individual fibres, typically finer than a strand of silk. That fineness is what gives microfibre its absorbency, its smooth feel and its ability to dry much faster than cotton. The 16-bottle figure per beach towel is a verified number under GRS 4.0 certification, not an estimate.
What GRS Certification Actually Means
GRS stands for Global Recycled Standard. It is an independent third-party certification that verifies two things: that the recycled content claim in a product is accurate and that the supply chain meets social and environmental standards.
Will and Wind holds GRS 4.0 certification, audited annually. That means an independent organisation has reviewed the entire supply chain and confirmed the recycled content at the quantity we state. This is a different thing from a brand saying it uses recycled plastic bottles based on information from a supplier that has never been independently checked.
For context on how GRS certification compares to other credentials like B Corp across 18 Australian towel brands, the best travel towels Australia comparison covers the full picture.
Is rPET Actually Better Than Virgin Polyester?
On the measures that matter most, yes. Producing rPET uses 85% less energy, 75% less carbon and 90% less water than producing virgin polyester from petroleum. It diverts plastic waste from landfill and ocean waste streams. These are meaningful differences at any scale.
The honest nuance: rPET is still a synthetic fabric. Like all synthetics, it can release microplastic fibres during washing. We do not pretend otherwise. The argument for rPET is not that it is perfect. It is that it is substantially better than the alternative on energy and material sourcing and that the plastic it uses already exists rather than requiring new oil extraction. More on the microplastic side in the sand free beach towels blog if you want to dig into that.
Does rPET Perform Differently to Virgin Polyester?
Functionally, the two materials perform very similarly. Absorbency, dry time, pack size and durability are essentially the same. The difference is supply chain and material origin, not the towel you end up holding.
This is worth being direct about because some people assume recycled must mean lower quality. It does not. Will and Wind towels are 200 GSM rPET microfibre, GRS 4.0 certified. The quality argument and the sustainability argument point in the same direction.
Why Every Will and Wind Product Uses rPET
Will and Wind was founded by people who spend a lot of time near the ocean. Plastic pollution in marine environments is visible, measurable and directly connected to the places the brand photographs and the wildlife that appears on every product. A humpback whale on a towel made from 16 recycled plastic bottles is a specific statement rather than a vague gesture.
For the full story on the conservation side of that, the marine conservation blog and the Our Photographers page tell it properly.
Frequently Asked Questions About rPET
What does rPET stand for?
Recycled polyethylene terephthalate. A synthetic textile fibre made from recycled plastic bottles rather than new petroleum.
Is rPET safe for skin contact?
Yes. The recycling and manufacturing processes clean and purify the material thoroughly. It is used in towels, activewear and bedding in direct skin contact every day. Will and Wind rPET microfibre is GRS 4.0 certified, which includes supply chain oversight.
How many plastic bottles go into a Will and Wind towel?
16 per beach towel. Verified figure under GRS 4.0 certification.
What is the difference between rPET and recycled polyester?
Same thing. Recycled polyester is the generic term. The r prefix just means the source is PET plastic, which is the specific polymer used in bottles and food packaging and the most commonly recycled form used in textiles.
