FAQs

Is 100% merino wool better?

There is a lot of debate about whether 100 merino wool is better than other types of wool. Some people believe that it is because 100 merino wool has a higher Twist Rate, which means that it twists more easily. Additionally, it has a lower Density, which means that it takes up less space in your fabric.

How tight should a merino base layer be?

A merino base layer should be tight fitting, to ensure a comfortable fit.

What percentage merino wool is best?

Merino wool is best for about 40 percent of all clothes.

Is alpaca wool better than merino?

There are a few key factors to consider when purchasing wool, including quality, fiber content, and cost. Alpaca is a type of sheep that is bred for its soft, fine fleece. While merino may be the more popular choice for clothing, alpaca can offer a higher quality fiber that is less expensive.

Conclusion

There are many different types of base layers and it really depends on what you will be using them for. If you are looking for a base layer that can be used for all activities, then a merino wool base layer is the way to go. However, if you are looking for a base layer that can only be used in specific conditions, then a cotton or linen base layer is the way to go.
