Buying A Merino Wool Base Layer 

Material:

Merino wool fabrics differ in density, porosity, and diameter of fibers. The fiber diameter determines the softness of the fabric; the smaller the diameter, the softer is the fabric. Merino wool fibers have a diameter in the range of 17 microns (Ultrafine Merino Wool) and 24 microns (Strong Merino Wool). Base layers are often made of fabrics with a density between 130 grams per square meter and 150 grams per square meter.

Fabrics could be blended with other materials such as nylon, polyester, and polyamide to improve the lifespan of the fabric. Even so, such blends also have their shortfalls; the fabric can become less soft to touch and more synthetic materials can decrease the breathability and odors of the fabric.

Seams:

Your base layer’s seams should not cause rubbing or chafing. To reduce any discomfort caused by the seams, manufacturers often use flatlock seams. Flatlock seams are especially vital when it comes to tight-fitting base layers.

Odor-resistance:

Merino wool is more resistant to the damaging effects of odor compared to other fibers because it contains lanolin, a wax that’s known to help deter bacteria from forming during those fibers. Synthetic materials can be decorated with antimicrobial agents as an attempt to emulate this property, but these durable treatments are quickly removed through washing.

Durability:

Pure merino wool is not as strong as synthetic fibers, nylon, or polyester. However, some manufacturers produce garments with merino wool blended with nylon to give them improved durability. This helps them to also make very thin and porous clothes without compromising its durability in any way.

Fit:

The fitting of a base layer impacts its performance; in low temperatures, base layers with a tighter fit are useful for heat environments, while loose-fitting base layers are useful for warm weather since they are more effective at providing ventilation.
