Oversized T-shirts have made their way into CrossFit boxes and functional training, even though they were born as a streetwear icon. For years they were associated with urban fashion and a relaxed look, with wide cuts and heavy fabrics.
And this is where the real challenge lies: the GSM. This technical detail, which almost nobody checks when buying a tee, completely defines the wearing experience.
An oversized T-shirt with 250 or 300 GSM (GSM means g/m²) can be perfect for winter or for a casual outing, but inside the box it becomes a burden: heavy, heat-trapping, sweat-soaking, stealing your energy instead of supporting your performance.
Training in a heavy T-shirt feels like training with a duvet on top of you
The key for training: 150 GSM
For an oversized tee to really work in training, the key lies at 150 GSM. That’s the sweet spot where style and performance come together:
Lightness and freshness
You move freely, without feeling the T-shirt as extra weight.
Total versatility
Perfect both for your WOD and to wear with jeans in your daily life.
Soft feel and fluid drape
It keeps the relaxed look without losing comfort.
Balanced durability
It withstands training and frequent washes without becoming weak or worn out.
At Cocowod we knew this from the start, which is why our oversized tees are made at 150 GSM* — making them the lightest and most comfortable on the market.
Check the following table to see how different GSM ranges are typically used.
| GSM | Recommended use |
|---|---|
| 120–140 | Underwear. Promotional T-shirts. |
| 140–150 | Casual wear. Warm climates. |
| 150–160 | Casual wear and sports tees. Ideal for side seams. This is the GSM of Cocowod tees. |
| 170–190 | Typical casual T-shirts. Mid-season wear. Everyday garments. |
| 200–220 | Streetwear-style casual wear. Garments with more drape and presence. Perfect for urban looks. Traditional oversized clothing. |
| 230–300 | Heavy oversized garments. Light coats. Clothing for cold climates or pieces where structure is prioritized over lightness. |
| > 320 | Sweatshirts, hoodies and coats. |
Our oversized model is a T-shirt that breathes with you, doesn’t interfere with your training, and keeps the essence of urban fashion without sacrificing athletic performance.
Because in the end, training with style is fine. But training with style and with the right tee is what makes the difference, inside and outside the box.
So go check out the collection of oversized T-shirts for men, or for women. And in the unisex collection you’ll also find many oversized models.
