Fleece fabric is commonly categorized by weight, typically measured in grams per square meter (gsm), which indicates its density and level of insulation. The different weights determine the fabric's warmth and suitability for various activities and conditions.
According to Trespass, the main different weights of fleece fabric are:
- Ultralight: Below 100gsm
- Lightweight: Between 100gsm and 200gsm
- Mid-weight: Between 200gsm and 300gsm
- Heavyweight: Above 300gsm
These classifications help consumers choose the appropriate fleece layer based on their intended use and the climate.
Fleece Fabric Weight Guide
The weight of fleece fabric directly correlates to its warmth and bulk. Here is a breakdown of the different weights, their descriptions, and typical uses, based on the provided reference:
| Weight Range | Description | Typical Use |
|---|---|---|
| <100gsm | Ultralight | Summer walking in cool weather |
| 100 – 200gsm | Lightweight | General wear, walking in temperate weather |
| 200 – 300gsm | Mid-weight | Outer layer in everyday wear or mid-layer in layering system |
| >300gsm | Heavyweight | Outdoor activities in Arctic conditions, as a thermal fleece |

Understanding Fleece Weights
Choosing the right fleece weight is crucial for comfort and performance.
- Ultralight fleeces are excellent for mild conditions where only minimal insulation is needed, or as a very thin base layer. They offer breathability and packability.
- Lightweight fleeces are versatile for everyday wear and moderate activity in cooler temperatures. They provide a good balance of warmth and comfort without being too bulky.
- Mid-weight fleeces serve well as a primary outer layer in cooler, dry conditions or as a substantial mid-layer when temperatures drop significantly, requiring a layering system for warmth.
- Heavyweight fleeces are designed for cold, harsh environments. They offer maximum thermal insulation, making them ideal for activities in freezing or arctic conditions where retaining body heat is paramount.
Selecting the appropriate fleece weight ensures you stay comfortable, whether you're on a casual stroll, hiking in the mountains, or facing extreme cold.
