Choosing the right fabric for custom men’s gym t-shirts can make or break your brand. Use the wrong material, and your buyers complain about sweat, smell, or stretch. Use the right one, and they’ll reorder again and again. So—what’s the best fabric in 2025?
The best fabrics for custom gym t-shirts in 2025 include polyester for moisture-wicking, spandex for stretch, nylon for strength, and bamboo or cotton blends for breathability and comfort. For B2B custom orders, polyester-spandex blends remain the top choice due to their durability, flexibility, and fast drying properties.
👉 Let’s break down each option so you can choose the ideal fabric for your product line.
What is the best fabric for gym t-shirts?
For activewear brands or sportswear wholesalers, polyester-spandex blends are the most popular choice.
- Polyester: Lightweight, quick-drying, and ideal for sweat management
- Spandex (Elastane): Adds 10–15% stretch, perfect for muscle-fit or slim cuts
- Blends (like 90/10 or 85/15): Combine performance and comfort
This combo is the standard for custom gym t-shirts in the sportswear fabric types category.
Polyester vs Nylon for workout shirts: which is better?
Both have their strengths:
- Polyester: Cheaper, dries faster, more widely available
- Nylon: Softer, more durable, but slightly more expensive
If your gym t-shirts are tight-fit or compression style, nylon-spandex may offer better comfort. For bulk fitness t-shirts, polyester is usually the go-to.
Is cotton good for gym t-shirts?
Cotton feels great on the skin—but holds sweat.
That said, cotton blends (like poly-cotton) are suitable for lifestyle gym wear, especially for lower-intensity workouts or casual athleisure.
👉 Avoid 100% cotton for high-performance sports use.
What about bamboo or natural fibers?
Bamboo fiber is gaining popularity in 2025:
- Naturally antibacterial
- Breathable
- Sustainable
But bamboo can be expensive and may not suit high-impact gym use unless blended. Use bamboo-cotton-polyester blends to create eco-friendly, breathable, but still functional gym t-shirts.
How to choose fabric for custom gym t-shirts?
Consider these key factors:
- Workout intensity – High sweat needs moisture-wicking fabrics like polyester
- Fit style – Slim cuts need more spandex fabric
- Target market – Casual or athletic, eco-conscious or cost-sensitive
- Printing method – Sublimation works best on polyester
- Country/Climate – Warmer regions may prefer breathable or mesh fabrics
For OEM/ODM buyers, always ask the sportswear fabric suppliers for swatches and GSM data before confirming bulk.
Where to source sportswear fabric suppliers?
You can find reliable sportswear fabric suppliers via:
- Industry fairs like ISPO or MAGIC
- B2B platforms like Alibaba, Global Sources
- Vertical manufacturers (like us 👋) who control fabric and stitching in-house
Always request fabric specs (composition, GSM, stretch rate) before sampling.
