Dock Rats / 28.09.2026
Two training tops can both contain polyester and still fit very differently. Fibre content alone does not tell you whether a garment is loose, close-fitting, thick or light. Read the composition alongside the construction and cut.
Start with how you will wear it
Do you need a loose top for the gym, a close layer under other clothing, or a T-shirt to change into afterwards? Identify the main thing you want: extra room, a closer cut or a particular feel. Use that to compare actual products.
Cotton is only part of the description
Dock Rats offers classic T-shirts and oversized cotton styles. The oversized shape comes from the width and shoulder placement, so do not assume that your size in another cotton T-shirt will produce the same fit.
Check the composition for your selected colour. Blends can differ within a product range. An organic cotton statement on one product applies to that product; it does not automatically describe every item in the collection.
Polyester, mesh and elastane
Polyester names a fibre; mesh describes a fabric structure. Our Technical range includes a loose polyester mesh T-shirt and closer-fitting base layers with elastane. These represent different fits even though both contain polyester.
Elastane is used in stretch blends, but a percentage is not a size guide. Read the intended fit and compare measurements. Do not infer compression, a particular drying time or waterproofing from fibre content alone.
What does g/m² mean?
Grams per square metre describes fabric weight per unit area. It is not the weight of the finished T-shirt. The number helps you compare fabric weight, but does not establish warmth, durability or quality on its own. Structure, cut and layering also matter to how the garment feels.
A useful reading order
- Choose a close or loose fit.
- Read the fibre content for your selected variant.
- Check the structure and any stated fabric weight.
- Compare measurements with relevant clothing you already wear.
- Read the care instructions before deciding.
