Best Fabrics for Cold Weather: Does Fleece Outperform Wool in Bib Overalls?

Choosing the Right Insulation

When it comes to selecting the best insulation for your bib overalls, consider several factors including warmth, weight, and moisture-wicking properties. Fleece is a popular choice among hunters due to its exceptional warmth-to-weight ratio. It can provide up to 3 times more warmth than wool while weighing significantly less, making it easier to move around in the field. For example, Polarguard fleece provides 3.5 times more warmth than down while weighing only 20% more.

Moisture Management

Fleece is also superior to wool in terms of moisture management. It dries quickly, reducing the risk of wind chill and discomfort. A good rule of thumb is to choose a fleece with a moisture-wicking treatment, such as Polarguard’s own Moisture-Wicking technology. This ensures that your fleece will keep you dry and comfortable even in the most intense hunting situations. For example, Polarguard’s Moisture-Wicking fleece dries up to 3 times faster than untreated fleece.

Practical Considerations

When selecting fleece for your bib overalls, consider the specific conditions you’ll be hunting in. If you’ll be hunting in extreme cold, choose a thick fleece with a high warmth-to-weight ratio. For example, Polarguard’s 2-layer fleece provides 10.5 CFM (cubic feet per minute) of insulation, while their 4-layer fleece provides 20.5 CFM. Additionally, consider the fabric’s weight and durability, as well as its ability to withstand wind and rain. A good fleece should be able to withstand at least 10 minutes of rain without losing its insulating properties.
