Uniqlo HeatTech | Bad – made from oil, does not break down, sheds tiny plastics |
Merino Wool | Good – comes from sheep, breaks down, less pollution |
If you want basics that are better for the earth, look for recycled polyester or brands that care about the planet.
Bamboo and Modal
Bamboo and modal basics feel soft and smooth on your skin. They keep you comfy and dry without making you itchy like some synthetics. These are good if you have sensitive skin or want something more natural.
Fabric Type | Moisture-Wicking | Comfort Level |
|---|---|---|
Bamboo | Excellent | High |

Bamboo basics from Cozy Earth or tentree keep you dry and comfy. Modal basics from Toad&Co feel silky and keep you warm. You can wear these for relaxing or under other clothes.
Note: Bamboo basics fight germs, so you can wear them longer before washing.
Silk Thermals

Merino Wool Alternatives
You may like how merino wool base layers feel. But sometimes you want something new. Maybe you have allergies or want to spend less money. Or you just want to try other basics. Here are some top choices that give you warmth and comfort.
Cotton Blends
Cotton blends are easy to find. You see them in basics from Hanes and Fruit of the Loom. Some sports brands use them too. These base layers feel soft and familiar. They are good for wearing at home or every day.
But cotton blends do not handle sweat well. When you sweat, cotton holds the moisture. It dries slowly and can make you feel cold. In very cold weather, wet cotton can be risky. It can make you lose body heat.
Cotton blends are cheap and comfy. But for sports or outdoor fun, pick something else. Merino wool base layers keep you warm even when damp. Cotton blends can make you chilly.
Tip: Wear cotton blends on mild days or inside. For hiking or winter sports, use natural base layers that handle sweat better.
Recycled Polyester
Recycled polyester, or rPET, is a smart pick. It works well and helps the planet. Brands like Patagonia and REI use recycled bottles and old clothes. These merino wool base layers alternatives wick sweat, dry fast, and feel light.
Here is how recycled polyester compares:
Aspect | rPET Benefits |
|---|---|
Energy Use | |
CO₂ Emissions | Cuts CO₂ by 50–60% compared to new polyester |
Water Usage | 20% less water than new polyester |
Performance | Same as regular polyester—wicks sweat, resists wear |
You get basics that work well and help cut waste. But recycled polyester may not last as long as merino wool base layers. It can shed tiny plastics when washed. This is not good for the earth.
Material | Durability | Environmental Impact |
|---|---|---|
Recycled Polyester | Not the best for durability; sheds microplastics when washed | Made from recycled stuff, but microplastics can harm the planet |
Merino Wool | Needs land and water for sheep, but breaks down naturally |
If you want basics that balance performance and care for the planet, recycled polyester is a good choice. Wash them in a laundry bag to catch microfibers.
Other Natural Fibers
You have more choices for natural base layers. Tencel, hemp, and bamboo are great options. These fibers feel soft and let air flow. They keep you comfy in many kinds of weather.
Hemp and organic cotton soak up sweat and let air move. You stay cool and dry, even when working out.
Tencel is soft and strong. It wicks moisture better than cotton. You feel dry and fresh. It also helps stop odor.
Bamboo gives you great airflow and comfort. It is nice when it is hot outside.
Natural fibers are breathable, absorbent, and comfy. They can be recycled and break down when you are done with them.
Lyocell is soft, gentle on skin, and manages moisture well. These are the three main benefits over other choices.
Natural base layers are good if you want basics that are kind to your skin and the planet. They break down after use, so they do not add to landfill waste.
