What Is Smartwool Apparel Made Of?

Smartwool is very passionate about getting people outdoors that they’ve dedicated themselves to creating gear that keeps people comfortable and confident when they venture into the wilderness.

To do this, they use Merino wool, which is a naturally occurring fiber that Merino sheep produce. As a result it is lighter and softer than regular wool making it ideal for wearing next to your skin.

Wool’s inherent properties enable athletes and outdoor enthusiasts to travel further and experience more, making it the ideal performance material for exploring nature.

Smartwool review

Why Choose Smartwool Socks And Clothing?

It’s Natural – Made of Proteins containing amino acids and naturally occurring compounds. Merino wool is a natural, renewable fiber, and you’ll find the Merino sheep are happy to hang out in temperatures ranging from 5 to 95 degrees.

It Assists in Temperature Regulation – When it’s cold outside, the natural crimps and bends in the fibers trap air, protecting you from the elements.
When the weather is warm, the fiber quickly transports sweat away from the skin, assisting in keeping you cool and dry.

It Assists in Maintaining a Dry and Sweat Free Environment – Merino wool wicks sweat and moisture away from the skin in the form of vapor.

It Appreciates When You Layer – At times, it’s bitterly cold outside, necessitating layering. By layering entirely in Merino wool, you create an escape route for sweat and excess heat.

It Is Odor Resistant – Merino wool is unique in that it absorbs bacteria’s odor, trapping it and preventing it from building up. Merino wool is ideal for traveling or longer treks when packing space is limited.

It Is Very Soft – The wool is wonderfully soft. It is so fine that it bends out of the way when it comes into contact with skin. Furthermore it cannot be prickly, as other wool fibers are, because it cannot support its weight. As a result, it is delicate.

It is a biodegradable material – After approximately 12 months in the ground, merino wool degrades. This means that when you’re finished with your gear, the earth will recycle this fibrous protein made up of amino acids, reintroducing carbon and nutrients into the soil.

It Contributes to UPF Protection – Merino fibers, depending on how they are spun and dyed, can help block out harmful sun rays (UPF 20+).

It is a Fire-Resistant Material – The majority of outdoor gear is used around campfires. Merino wool does not typically melt or catch fire. Nylon begins to melt at approximately 320 degrees, while polyester begins to melt at approximately 452 degrees.

Where Are Smart wool products made?

Smartwool socks are made in the United States of America from the finest Merino wool worldwide. Above all, the brands products are made with the finest Merino yarn available, sourced from sheep raised in some of the most breathtaking locations on the planet. Places like New Zealand’s and Uruguay’s magnificent ranches.

Then, American Southeast’s craftsmanship expertly transform fiber to form, ultimately producing the world’s best performance socks right here in the United States.

Smart Wool Hiking Socks Review

Smartwool hiking socks do not match up to any other hiking or winter socks, especially in terms of style, comfort, performance, and value.

Their high-performance mid-weight hiking socks are perfect for warm and cooler weather hiking when a sound insulation layer sock is required.

The hiking socks feature shearing, which is premium-quality calfskin; the socks almost feel like your own skin because of how soft and gentle they are on the feet.

Many thousands of air bubbles have been included in Smartwool socks to help give the socks their quick-drying, perspiration-wicking qualities. Furthermore the socks are created to keep your feet warm in the winter, but they also include excellent temperature regulation, which keeps your feet cooler in the warmer weather months.

Smartwool hiking socks also have the advantage of enabling your feet to breathe. The breathability of the booty allows your feet to dry out even when you’re putting in lots of effort. There is no residue left in your shoes because your feet stay dry, and therefore your shoes don’t smell.

Here are some of our favorites:

Customers gave these hiking socks an impressive overall average rating of 4.9-stars, with 100% of reviewers stating that they recommend them.

Reviewers shared that the socks feel true to size.

Having always been a fan of Smartwool socks for the winter, I ordered several pairs (yes, I went overboard and ordered three pairs of each color offered) of these mini socks. I have several pairs that I bought probably 4-5 years ago that I love. I was not disappointed. They are of the same high quality that I have come to expect from Smartwool. I waited to write this review until I had worn and washed the socks several times.

First, they were true to size when they arrived and fit perfectly after many washings (and dryings)! They are soft, comfortable, provide nice cushioning, and have just enough “give” to them. I would highly recommend them, and would hope that Smartwool will come out with some lighter colors, too! These are of the same high quality as those I bought a few years ago!

SmartWool Base Layer Review

As your next-to-skin piece of clothing, a base layer plays a vital role in wicking moisture away from your body and regulating core temperature. While a nice down jacket is far easier to justify, a base layer can be just as important for skiing, hiking, and climbing activities.

IntraknitTM Merino smart-wool base layers have fewer seams, a more articulated performance fit, and body-mapped ventilation to reduce bulk while allowing more movement. They’re breathable, flexible, and ideal for keeping you warm in changing weather and high-intensity activities.

Like the sock quiz, before you check out the wide range of Smart-wool base layers, a great place to start is the Perfect base layer quiz.

You’ll be asked a few questions:

  • Your gender
  • What temperature you’ll be wearing your base layer
  • The weather conditions you’re expecting
  • What base layer you are looking for
  • What adventures will you take your base layer on
  • How active you’ll be
  • How hot you get

When you’ve answered these quick and easy questions, Smartwool will take you to your personalized recommendations.

I like these bottoms; they are comfortable all day while skiing. Only bummer is how easily the intraknit snags…The first time I put on these leggings, they caught super easily and snagged while I adjusted them, making me question the integrity of the craftsmanship.

I still really like these leggings, but I really wish that wasn’t the case! I love to use my gear hard and for many years, and I am curious to see how long these layers last due to this.

 Love this top. Had my reservations, itchy wool? Not to worry, very soft and comfortable and warm. Size? Not to worry, other reviewers suggested to size up. Here is what I love: colors and pattern, fit which is close and slim, and sleeve length is good, and love 1/4 zip. I was reluctant to buy a wool garment that was in close contact with skin, but after purchasing merino wool in NZ, I was sold and on the lookout for another! Would definitely recommend highly. Price is on the high side, but I am confident it will be a keeper for a long time.

five-star review @ Smartwool

I have three Smartwool baselayer tops, and they are all size small and fit well. This one in small size was very tight, shorter, and not as stretchy, so I sent it back. For a frame of reference, I’m 5’4″ and weigh 110. The fabric has a nice-looking pattern, but since I’ve found Smartwool sizing to be unreliable lately, I’m not sure whether I want to try the medium.

Two-star review @Smartwool – This review was replied to by Smartwool who advised the customer to get in touch with them.

Five customers have given these men’s thermal bottoms an average review rating of five stars.

Reviewers thought the pants fit well; they were not too bulky and kept them warm.

This product is phenomenal. The stitching in the knees makes movement feel even better. I went snowboarding with these and my snow pants – I didn’t need anything else to stay at the perfect temperature. I love them and plan to order more.

Five-star review @smart-wool.

The Men’s Intraknit Merino sport fleece retails from $160.

Reviewers gave the Smartwool fleece jacket an average 4.7-star review rating.

Customers thought the material was light but warm, and this casual jacket had a good design.

I live in Indianapolis, IN. So this hoodie is all I need, most days. But it is also thin, so my biker jacket fits nicely over the top. My only request is for pants to exactly match. If you are wearing this hoodie, make sure to zip up the pockets because everything will fall out when you sit down.

Five-star review @smartwool.

How Do You Wash Smartwool Socks and Clothing?

You can wear Smart-wool’s merino wool for days without needing to be washed, as the Merino wool fibers absorb odor-causing bacteria, preventing them from reproducing or growing on their surface. This aids in reducing odor in your socks, shirts, and bottoms, which means you won’t have to wash your clothes as frequently.

Simple Merino wool care will ensure that your Merino socks, base layers, and other clothing look as good as they feel. While it is generally acceptable to wash Merino wool Smartwool products, it is critical to check the tag on each garment for the best results.

Washing Guidelines

  1. Turn your socks and garments inside out.
  2. Machine-wash in warm or cold water on a gentle cycle (avoid hot water as heat may shrink wool).
  3. Use a mild soap and avoid bleach and fabric softener (bleach ruins the Merino wool fibers, while fabric softener coats them, impairing their natural ability to manage moisture and regulate body temperature).
  4. While most Merino products can be tumble dried, Smartwool recommends air drying to minimize your environmental impact and extend the life of each product. Lay your wool garments flat to dry (hanging wet wool may distort the shape). If you prefer to dry in the dryer, set it to the lowest setting. Additionally, read the care label as you should not dry several of smart wool products in the dryer.

About SmartWool

Smartwool is an American company founded in 1994 in Steamboat Springs, Colorado, by New England ski instructors Peter and Patty Duke when they wanted to ski for more extended periods without getting cold toes.

The company discovered the performance benefits of Merino wool as a fabric. The fabric was soft, moisture-wicking, thermoregulating, sustainable, and odor-neutralizing. All of which contributed to keeping their feet dry, comfortable, and warmer for longer than the synthetic socks they were wearing until that point in time.

The Timberland Company acquired Smartwool in 2005, and Smartwool became a subsidiary of VF Corporation following VF Corporation’s acquisition of The Timberland Company in 2011.

In 2010, Smartwool signed a contract with the New Zealand Merino Company to source its Merino wool exclusively.

The Smartwool community comprises individuals who believe that time spent outside is beneficial, restorative, and necessary for everyone.

The company was the first outdoor company to manufacture performance Merino wool ski socks, revolutionizing the category and permanently altering how outdoor enthusiasts viewed their feet.
