Best Wool Running Gear for All Seasons

Looking for gear that keeps you feeling warm when needed, avoids a chill by also keeping you dry and prevents overheating? Welcome to the wide world of the best wool running clothes!

You have so many materials to choose from like synthetics, including polyester or nylon, or natural options like bamboo and wool. There are even blends with a mixture of synthetic and natural fibers.

Stick with us as we dig into why wool, specifically Merino wool, is a go-to performance fabric for all kinds of weather. And then check out some of our favorite wool gear for runners.

Why Merino Wool for Running Gear?

Wool, particularly Merino wool, has become a go-to choice for running fabrics. Why?

It’s an incredibly versatile fabric.

It’s known for its moisture wicking capabilities and its breathability, which helps our bodies regulate our temperatures regardless of the season. How does it do this? It traps air to provide insulation while moving moisture away from the skin.

Merino wool is also odor-resistant and resists stains, and can be blended with other fibers, which can help with durability. You may find you don’t need to wash Merino wool gear as much as synthetic gear thanks to the odor-resistant qualities. Line dry after wearing and it’s ready to go for your next run.

Wool has a place in your wardrobe, regardless of whether you’re tackling summer runs or cold-weather runs.

Best Wool Gear for Runners

We’ve compiled a list of some of our favorite wool gear items. These are all made with merino wool, usually a blend with synthetics. An added bonus is that this gear will also be useful for cross-training, camping, hiking, or even everyday wear.

Best Summer Wool Running Socks – Darn Tough Stride Micro Crew 

Darn Tough socks are just that: Darn tough!

The Stride Micro Crew Ultra-Lightweight running socks are made from anti-chafe Merino wool with a next-to-skin fit making them super comfortable to wear.

The socks boast extra durability knit into the heel, footbed, and the outside toes. They’re performance socks so no slipping, bunching, or blisters are to be expected. The Merino wool also ensures the socks provide excellent breathability and dry quickly.

Like PAKA socks, these come with a lifetime guarantee.

Best Winter Wool Running Socks – Smartwool Running Socks

Winter means your toes often feel like popsicles, and that isn’t terribly pleasant when you’re pounding the ground.

But super thick socks can mean sweaty feet, which also become cold…what’s a poor determined runner to do?!

Merino wool is a fiber you can wear year-round thanks to its ability to regulate temperature, wick moisture, and resist odor.

This makes it perfect for winter, as it keeps your feet warm while still being moisture-wicking. These socks feature a performance-oriented fit and a mesh ventilation design.They also call their wool technology ‘Indestructawool,’ which features a construction method that’s known for its incredible durability. So, if you’re looking for running socks that’ll last, these are the ones for you!

The one thing to remember when looking at winter socks is that as they get thicker, you need to consider replacing your shoes to ensure they don’t become too tight and cause blisters.

What’s great about Smartwool is you can get a variety of designs and also heights. They are a MASSIVE hit among trail runners and winter runners.

Best Wool Long-Sleeve Running Shirt – Tracksmith Brighton Base Layer

The Brighton Base Layer long sleeve running shirt is a shirt I’ve recommended in the past.

It can be worn on its own, but also serves as a great base layer with a jacket or vest. It boasts a comfortable fit that’s not too loose but not too tight.

It’s made from an engineered Merino mesh for a seamless and lightweight fit. The core of the shirt is a mesh that’s more open, while the sleeves are made with a closed knit to keep your arms warm.

Tracksmith can run a bit smaller so consider sizing up for a looser fit.

Best Wool Short Sleeve – Icebreaker Merino Sphere II Short Sleeve T-Shirt

Since you’re most likely wearing short sleeves in warmer temps, a great Merino wool option for warmer weather is the Icebreaker Merino Sphere II short sleeve. This is a merino blend tee using their Cool-Lite jersey fabric for breathability, odor resistance, and comfort.

This shirt also has offset shoulder seams to reduce friction and a drop tail hem for a little extra coverage in the back.

Best Wool Running Gloves- Ibex Merino Wool

These are such great year-round gloves. Merino wool is that perfect lightweight for those chilly spring and fall mornings. It’s going to easily wick away sweat, providing just the right level of warmth.

These gloves feature a conductive material on the index finger and thumb that definitely works. We’ve worn these a lot and were really impressed that you could fully use your phone.

A definitely winner for me. Especially because they are thin enough to also pair with another mitten when temps really drop.

The small also actually fits my hand well, even as unisex.

Best Wool Running Tights – Smartwool Active Fleece Tights

These tights are super comfortable and designed for those truly cold winter days! I love me some fleece because it too wicks away, so combined with the wool it’s a winning strategy to not get chills on those sweaty cold runs.

I love that they have thigh pockets that are great for an ID or credit card, or even a cell phone (we know I find this to be an important feature in tights now). They also have a high-rise and wide waistband that doesn’t roll down.

Best Wool Running Beanie – Smartwool Merino Beanie

This lightweight beanie can actually be worn year round, believe it or not. It’s great for running, skiing, under a bike helmet, you name it! Truly I’m a gal who NEEDS a beanie to get out the door for winter runs, so this is something you’ll see on me a TON in a variety of styles.

The beanie is made with Merino 150 fabric for solid durability and is one size fits most.

There are a few styles like if you want fleece for an even warmer option or a long option because you like to roll it up or have a bigger head :).

Best Wool Running Underwear – PAKA Underwear

The PAKA performance underwear has great reviews and I will add my name to that list! These are made from alpaca wool and are great for running, mountain biking, and other activities.

Like Merino wool, alpaca wool provides similar thermoregulating features. They dry quickly, faster than many other types of wools. The wool also has a lighter feel thanks to air pockets in alpaca fibers. And just like Merino, alpaca wool is naturally odor-resistant.

They are so thin and light, I’m absolutely a fan of how they feel to wear anytime next to my skin. But an extra win on the run for any temp. Also available as briefs for our gentleman runners.

A major win to have that anti-odor and anti-microbial feature!

Best Wool Sports Bra – Branwyn Essential Racerback Sports Bra

Yes, just like with the underwear, wool sports bras are a thing.

Shawna created Branwyn because she couldn’t find anything that felt good to wear during a workout; most options were polyester or cotton, which don’t exactly scream breathable, especially while running.

After tons of research and testing, she landed on what she now calls the perfect pair made of a combo of Merino wool, nylon, and elastane.

The material is soft, moisture-wicking, and odor-resistant. Basically, exactly what you want when you’re sweating during a workout or on race day.

Plus, it comes in a few muted colors that won’t stand out too much when layered with a tank top or other cold-weather outer layer.

Best Outer Layer – Tracksmith Nor’Easter Jacket

If you’re a cold weather runner, a great outer layer option is the Tracksmith Nor’Easter Jacket. While pricey, this jacket provides a lot of bang for the buck.

The exterior shell repels water and wind, while the Merino liner provides the warmth you need without bulky layers. It has zippered pockets for storage and a few small reflective details.

Listen, I’ll give it to you straight…this is a jacket I’d wear around town, but if I were shelling out $$ for a running jacket, it would be one from our list of best running jackets.

Best Wool Running Headband – Smartwool Printed Headband

This headband has a nice wide size and a great multicolor print. The exterior is 100% polyester, while the inside is a Merino wool blended with polyester for improved durability over the long haul.

This would be great throughout the winter months on the trails and roads.

What to Look for in Wool Running Gear

There are a couple things to keep in mind when looking at wool running gear. While there are a lot of different types of wool based on the animal (hello Alpca’s vs sheep), you’ll tend to see mostly merino in running gear.

Blends

For example, as mentioned Merino wool is often blended with other fibers, usually synthetics like polyester and nylon. In addition to helping with durability, it reduces cost and the weight of the fabric.

You can get 100% Merino wool products, but don’t shy away from the blends for a better price point.

Weight

When looking at clothing items, pay attention to fabric weight and the style and fit of the items. Sometimes companies share the fabric weight as grams per square meter (GSM). This may be reported as a number like 150-gsm, which would be a lighter weight top, or described as lightweight, mid weight or heavyweight.

For reference, 200-gsm and above are mid to heavy weight fabrics.

In regards to style and fit, base layers should fit snug against the body. These should feel soft on the skin without needing additional layers underneath and may be warm enough to wear alone on warmer days.

Midlayers may be heavier and looser and can be worn with a jacket or vest on colder days.
