    5 Reasons to Choose Merino Wool Clothing

    Is Merino wool itchy? Is Merino wool warm?

    Here are the top benefits of Merino wool.

    1. Odor Resistance

    Merino wool is naturally antibacterial.

    To put it simply, it doesn’t smell. In a way it’s resistant to it.

    Well, of course, you shouldn’t expect wearing Merino pants or Merino base layer (Best Merino wool base layer for women) for months on end without washing them and feeling fresh. No, it won’t happen. You won’t feel fresh and nice that long. It’s just that Merino isn’t prone to absorbing odors.

    It keeps you fresh much longer than most other fabrics.

    2. It’s a Natural Material

    Merino wool is a wool from merino sheep (New Zealand, Australia).

    As a natural material it’s also much safer than synthetics for most us. No itching. No allergic reactions. In fact, Merino wool allergy neutrality is one of the top reasons why people choose Merino clothing not only for sports, but also for everyday.

    Being 100% biodegradable, Merino wool is also better for the planet.

    3. Outstanding Moisture Management

    Merino wool adjusts to you and the environment you are in.

    If it’s hot, it keeps you cool by transporting all the sweat and moisture away from your skin. If it’s cold, it keeps you warm. It keeps you fresh and comfortable in all conditions, even when it’s getting slightly dump. It’s all possible due to its fully natural moisture management system and moisture wicking features.

    Speaking of the cold weather and winter activities, in order to stay warm it’s equally important to choose the right fabric weight — not all Merino wool base layers will keep you warm on cold winter days.

    4. Breathability

    Great breathability is a must in a base layer pants and shirts.

    It’s what allows you to keep going long while staying comfortable.

    5. Ease of Use and Longevity

    Not only Merino is durable, but also easy to take care of.

    Merino wool is machine washable. However, make sure to refer to the care instructions of the manufacturer of your shirt or pants, as they may differ. For the most lightweight Merino base layers, hand wash is the safest choice in long term.

    How to Find the Best Merino Wool Base Layer Pants For Yourself?

    How to find the best Merino wool base layer for yourself?

    Let’s make this super simple.

    Generally speaking mostly it’s about these 3 simple things.

    1. Fabric Weight

    What are you going to use it for? In what weather? Do you need these base layer pants for hiking and sports, or you plan to use them only for camping? Will you use them at home or for daily commute?

    Fabric weight is one of the main characteristic of Merino wool clothing.

    These 160 GSM, 200 GSM, 250 GSM (other times – g/m2), … to put it simply, they show how thin or thick is the fabric. The bigger the number, the warmer this base layer or these base layer pants will be. If you want something for everything, look for 200 – 230 GSM. They are usually called midweight base layers. For cold weather and, especially for activities that include a lot of sitting or standing in one position, look for base layer with GSM of at least 250.

    If you want the most lightweight base layer — 165 – 180 GSM.

    2. Style and Fit

    Are you planning to wear it on its own?

    There are several kind of base layer pants. While some look great also when you wear them on their own, others are made to be worn under or for sleeping only. Take that into account when choosing base layer pants for yourself.

    3. Your Budget

    Decide upon your budget.

    And choose the base layer pants that fit into it, and the ones that suit your needs the best. There’s no reason to pay more for features you don’t need. Likewise, it’s not a good idea to get cheap Merino wool base layer pants, if you plan to use them a lot — higher price often also means better quality and comfort.
