The ultimate guide to vegan winter base layers for the best cruelty-free options to keep you warm whilst exploring in the cooler months

Vegan winter base layers are something the vegan outdoors community is constantly on the lookout for. The majority of base layer options on the market contain wool and with good reason.

Wool is a good insulator as it has a lot of desirable properties and it’s biodegradable. This is partly why this article has been such a long time coming. Finding performance vegan base layers that live up to their wool counterparts has been HARD.

There’s also a big question mark about whether they’re more harmful to the planet in the long run as they’re made from synthetic materials.

The cruelty that can be associated with the wool industry remains though. This is a big reason why vegans and animal lovers choose to avoid wool and are on the hunt for cruelty-free base layers.

After some research, we found the best vegan winter base layers to enable your winter adventures, whilst being animal-free!

What to Consider When Choosing Base Layers

There are a few things to consider when choosing a base layer for outdoor activities. Lightweight breathable baselayers are more suited for warmer temperatures but in this post, we’re going to cover winter and thermal base layers for cooler temperatures.

Base layers are an essential part of kits for winter. They act as a second skin, insulating and regulating your body’s temperature. They help to keep in the warmth your body generates, whilst also wicking away sweat to keep you dry and warm. They’re designed to reduce chaffing whilst offering freedom of movement and easily allow for extra layers on top.

A few things to consider when choosing a base layer:

  • Warmth – For winter particularly you need your base layer to be warm. Base layers that are brushed or fleece-lined will provide more warmth however this is often at the sacrifice of breathability.
  • Breathability – Super important when exerting yourself as you want to regulate your body’s temperature to stay comfortable throughout the day. An item’s breathability is its capacity to let moisture be absorbed and evaporated through the fabric. Some base layers have vents around specific areas to allow air and moisture to easily pass through the material. As I mentioned, it can be a toss-up between warmth or breathability but a good base layer should offer both.
  • Weight – Because base layers act as a second skin, you want them to be light rather than weigh you down. Winter base layers are heavier compared to summer base layers in order to provide more warmth.
  • Use – Depending on what you’re doing outside, you’ll likely need different base layers. If you’re alpine climbing during the day, you’ll want a base layer that provides breathability as you’ll be working up a sweat. Come nightfall, when you’re hunkering down in your tent, breathability isn’t as important and warmth becomes more of a priority.
  • Wicking – Fabrics with wicking technology pull moisture from your skin as you sweat then allow it to pass through the fabric. This is important to keep you dry and warm, as water on your skin in cold conditions can soon become cold and possibly freeze.

Vegan Base Layers vs Non-Vegan Base Layers

First off we need to answer what makes base layers not vegan.

A lot of winter base layers are made from merino wool which comes from merino sheep. They are reared and sheared to make items of clothing before being killed for their meat.

Merino wool is favoured because it has a lot of beneficial uses in base layers. It’s lightweight, provides warmth, its breathable with natural moisture-wicking properties and it’s natural. It is often more expensive than synthetic materials but you can find base layers that are a hybrid of merino and synthetic materials that are more affordable.

Being a natural compound, wool is also biodegradable. So, although some synthetic options are made from recycled materials, the jury is out on which has a more negative impact on the environment in the long run.

Shearing Sheep for Wool

When it comes to the process of rearing and shearing sheep, this can be cruel. It can involve mulesing, where flaps of skin are cut from the sheep to prevent flystrike. The shearing process can also cause harm to sheep resulting in injuries and sometimes death.

This is of course not the case for all sheep farms but a lack of transparency in the industry makes it difficult to trust how sheep are treated in the wool industry.

As this process can be cruel, vegans choose not to wear wool, instead opting for animal and cruelty-free materials, which we’ve listed below.
