rPET vs. Cotton: Which Material Should You Choose for Your Custom Merch?
Choosing between rPET and cotton for your custom merch? Both are great options with different strengths depending on your brand values, use case, and target audience. In this guide, we break down the key differences to help you decide which fabric makes the most sense for your project — whether you're printing T-shirts, totes, or accessories with Nerds.
1. What Is rPET?
rPET stands for “recycled polyethylene terephthalate.” It’s a fancy way of saying recycled plastic — often made from used bottles and containers that are cleaned, shredded, melted down, and spun into fibers.
This gives plastic waste a second life, turning it into useful products like bags, outerwear, and some T-shirts. At Nerds, we use rPET for products where durability, moisture-resistance, or structure matters — especially in backpacks, jackets, and eco-forward swag.
2. What Is Cotton?
Cotton is a natural fiber made from the fluffy fibers of the cotton plant. It’s breathable, soft, and widely used in apparel — from lightweight T-shirts to heavy hoodies. At Nerds, we work mainly with organic or combed cotton, which feels better, lasts longer, and has a smaller environmental footprint than conventional cotton.
Cotton is the go-to for apparel that’s worn close to the skin or that needs to feel soft, cozy, and premium — like the Creator 2.0 or the Cruiser hoodie.
3. Sustainability Showdown: Which One Wins?
Both rPET and cotton have sustainability benefits — but they shine in different ways.
♻️ rPET: Closing the Loop
By using recycled plastic, rPET helps reduce landfill waste and limits the need for virgin polyester (which is petroleum-based). It’s energy-efficient to produce and supports the circular economy. Perfect for brands that want to show they're upcycling and reducing plastic waste.
🌱 Cotton: Natural and Biodegradable
Organic cotton is renewable and biodegradable, making it better for the soil and safer for the people growing it. It requires less water and no harmful pesticides compared to conventional cotton. Great for eco-conscious clothing lines or wellness/lifestyle brands.
4. Performance: Feel, Durability & Printability
When it comes to wear and performance, here's what to consider:
- 🧺 rPET: Strong, water-resistant, wrinkle-resistant, and quick-drying — ideal for bags and outerwear. Less soft than cotton but more durable.
- 🧶 Cotton: Softer and more breathable, ideal for everyday apparel. Absorbs moisture and holds color beautifully in prints.
At Nerds, we help match the right fabric to your needs — because nobody wants a crunchy tote or a soggy T-shirt.
5. When to Choose rPET vs. Cotton
If you’re stuck between the two, think about use, feel, and story. Here's a quick cheat sheet:
- 🏃♀️ Choose rPET for: Sturdy, structured products like duffels, laptop sleeves, windbreakers, and travel accessories.
- 👕 Choose Cotton for: T-shirts, sweatshirts, and products where softness, breathability, and everyday comfort matter most.
