Wool baselayers or synthetic baselayers?
The choice of a wool baselayer or a synthetic baselayer depends on several factors such as intensity, activity and weather conditions.
The multi-layer principle is a good rule of thumb on how to dress, as well as whether you're doing low or high-intensity activity with short or long breaks.
Wool baselayer
For longer walks or low-intensity activities, wool is the best choice. Wool can absorb up to 30% of its own weight in moisture and has excellent moisture-wicking properties that keep you warm even on cold days and during stationary periods, and even after getting wet or sweaty. Good, snug-fitting merino clothes are soft and comfortable against the skin and are highly versatile.
For overnight stays, wool baselayers and training clothes are also ideal. Wool is self-cleaning and can be used several times before it needs to be washed. Simply hang it up to air between uses.
Synthetic baselayers
Lingerie is made from synthetic materials such as polyester and polypropylene. With its moisture-wicking properties, the synthetic baselayer is ideal for high-intensity activities such as running and cycling. These clothes are light, comfortable and dry quickly, but odors quickly settle after exercise and so you need to wash them between uses.
Combination of wool and synthetics.
Ulvang has clothes in a wool and lyocell blend to provide the ultimate comfort and function needed during exercise. A blend gives you the best qualities from both wool baselayers and synthetic baselayers, with the heat, moisture-wicking and quality needed for high-intensity training.
In short, this means that synthetic baselayers or a blend is best for short and high intensity training, such as running or cycling where you can change your clothes afterwards. If you are doing long walks or sessions with lower intensity and quiet periods, wool baselayers are the way to go.
Washing
Wool clothes are an investment and, like all other things, they need to be taken care of and washed properly to prolong their lifespan. Wool is naturally antibacterial and doesn't need to be washed between uses, but when it’s time to wash it, there are several things to keep in mind.
Use a wool program on your washing machine and do not use fabric softener. Instead, opt for a wool wash like this one or wash without. Hang dry and do not tumble dry.
