12 best smartwool base layers
Smartwool base layers are high-performance clothing products designed for outdoor activities, including cycling and various sports and recreational pursuits. These base layers are designed to provide comfort, moisture management, and temperature regulation. Here's what you should know about Smartwool base layers:
Material: Smartwool base layers are made from merino wool, which is renowned for its natural properties. Merino wool is soft, moisture-wicking, breathable, and naturally odor-resistant. It also has the ability to regulate body temperature, keeping you warm in cold conditions and cool in hot conditions.
Moisture Management: One of the key features of Smartwool base layers is their moisture-wicking capability. Merino wool fibers can absorb and release moisture, keeping sweat away from your skin and helping you stay dry during physical activities.
Temperature Regulation: Merino wool has excellent insulation properties, which means it can help regulate your body temperature by trapping warm air close to your skin when it's cold and releasing excess heat when it's hot. This makes Smartwool base layers suitable for a wide range of outdoor temperatures.
Odor Resistance: Merino wool is naturally antimicrobial, which helps prevent the growth of odor-causing bacteria. This feature keeps the base layers smelling fresh even after prolonged use.
Comfort and Softness: Smartwool base layers are known for their softness and comfort.They are often designed with flatlock seams to prevent chafing and irritation during physical activities.
Fit and Styles: Smartwool offers a variety of base layer styles, including crewneck tops, long-sleeve tops, and bottoms like leggings or shorts. These base layers come in different weights, allowing you to choose the level of insulation that suits your needs.
Versatility: While Smartwool base layers are popular for outdoor sports like cycling, hiking, skiing, and running, they can also be worn as everyday clothing in cold weather. Their versatility makes them a valuable addition to any outdoor enthusiast's wardrobe.
Layering: Smartwool base layers are designed to be worn as the first layer of clothing, closest to your skin. They provide the foundation for a layered clothing system that helps regulate your body temperature in varying conditions.
Care: Smartwool base layers are typically machine washable, but it's important to follow the care instructions provided by the manufacturer to maintain their performance and longevity.
In summary, Smartwool base layers are high-quality clothing items made from merino wool, prized for its natural moisture-wicking, temperature-regulating, and odor-resistant properties. These base layers are designed to enhance comfort and performance during outdoor activities and are suitable for a range of sports and outdoor adventures.

| Question: | I am 5'3, 34B bust, 145 lbs. What size should i order |
| Answer: | Probably medium. I got a large for my 5'4" 165 pound frame and same bra size. |
| Question: | I have a long torso. In the picture the shirt looks like it is short in the torso. How long is the length (L size |
| Answer: | If you have a long torso I would skip this brand. I have a normal length torso but a large chest and thus this shirt is always creeping up. I still wear it as a base layer bc it's always covered by another layer, and it's nice and warm, but it's definitely short. |

| Answer: | I bought and used this top and the matching thermal pants last winter. Excellent material, soft not scratchy and very very warm! It held up beautifully. Most womens clothing items last one season due to poor cheap fabrics. I did not notice any wear and expect it to last multiple seasons. I washed on gentle and hung them inside out to dry as one should with wool fabric. Dried overnight without issues. |

Great For Layering
Many times a thermal shirt ends up being too hot over the course of a day, while some are too thin and require more layering than seems normal. This women’s Merino wool shirt acts as a perfect base layer or mid-layer, keeping you comfortable as the day goes on without being bulky.
Keeps Odors At Bay
Outdoor activity can cause women to work up a sweat that sometimes permeates clothing with odor, making it hard to enjoy the rest of your day. The Meriwool thermal shirt offers natural odor-resistant properties, keeping you smelling feminine and fresh no matter what your plans entail.
No Unwanted Moisture
Thermal shirts for women naturally create warmth, but along with that can come sweat and moisture that can weigh you down. The Meriwool Merino wool shirt offers moisture wicking abilities with its 250g/m2 weight interlock-knit fabric and helps you to stay warm and dry during outdoor activities.
Great For Any Occasion
Thermal shirts for girls and women that truly fit well can be tough to find, but the Meriwool thermal shirt features a unique shape that’s great for any weather conditions. From sun to snow, hiking, camping, running, and more will all be that much more enjoyable when you wear this shirt.
Adaptive Clothing
Unlike other textiles, Merino wool is a reactive material that adapts to your body's temperature. It regulates so that you are never too hot or cold in any weather.
Naturally Warm
Originating from Merino sheep from Australia that endure temperatures as low as 5 degrees, Merino wool is a lightweight, naturally warm fiber.
Itch-Free
Unlike regular wool fiber that is heavy, coarse, and itchy, Merino wool actually has thinner, finer fibers that make it soft to the touch and cause no irritation to the skin.
Ultra Soft
Merino’s fibers are much smaller in diameter than other wool which gives the fibers the ability to bend softly with increased flexibility. The result? Soft to the touch.
