What are the Best Materials for Hiking Baselayers?

Baselayers. They're not all made equal. So let's take a look at what materials are best when it comes to hiking baselayers.

When it comes to hiking in any season, choosing the right baselayer can make all the difference between a comfortable time of it and a frankly miserable and sweaty outing.

Baselayers are the layers you wear at the bottom – they’re the ones in contact with your skin. It’s their job to help to regulate your body temperature, wick away moisture, and provide a level of comfort that keeps you focused on the trail ahead. But with so many materials available, which ones are best suited for your hiking adventures? Let’s dive into the top choices and explore their pros and cons.

Why the Right Baselayer Material Matters

Your baselayer is critical for managing moisture and maintaining your body temperature. Hiking involves varying levels of exertion, which means you’ll likely sweat, especially during uphill climbs. A good baselayer material wicks moisture away from your skin, keeping you dry and preventing chills when you stop moving or face colder conditions.

Key Qualities to Look for in Baselayer Materials

  • Moisture-Wicking: The material should pull sweat away from your skin. This is incredibly important.
  • Breathability: It should allow airflow to keep you cool.
  • Thermal Regulation: The fabric should insulate in cold weather but not overheat in warm conditions.
  • Odour Resistance: Some materials combat odour buildup, an essential feature for multi-day hikes where you may well not have the luxury of laundry at the end of each day.
  • Comfort: The fabric should feel good against your skin and not cause irritation.

You’ve got 2 main choices – synthetic fabrics or merino wool. Let’s take a look at the pros and cons of each.

1. Merino Wool

Let’s have a look at the pros and cons.

ProsCons
Moisture-WickingCost – it’s typically expensive!
Temperature RegulationDurability – doesn’t last as long as synthetics
Odour Resistant (hides those post hiking sweat stenches pretty well)Drying Time – not an easy one to try on a quick overnight stop 
Soft and Comfortable 

I’ve got 2 merino wool baselayers and I love them for winter hiking in particular (though less so in the Spring, Summer or early Autumn months). 

It’s so comfortable against the skin and really effective when it comes to moisture wicking. But it’s definitely on the pricey side.

The one thing I would say is that I’ve worn the same merino wool baselayer 2 days running (don’t judge me – I was supposed to have access to a washing machine but it didn’t work out that way!). And there was no odour. So on the whole a really solid choice but a tad too warm for me in milder months and frankly really pricey if you need a few.

2. Synthetic Fabrics (Polyester, Nylon)

Here are the pros and cons of sythetic baselayers.

ProsCons
Fast-DryingOdour Retention
DurableLess Breathable
AffordableComfort

Most of my baselayers are synthetic materials. They are ultimately decent when it comes to sweat wicking. They’re a little less comfortable and luxurious feeling than merino wool, but I find them typically really breathable, very cost effective compared with merino wool and also incredibly breathable.

My synthetic baselayers also dry much much quicker than merino wool ones.

Newer options

I’ve not tried one myself but some companies are creating baselayers from bamboo fibres. I’d love to hear from you if you’ve tried these and what your experience was!

Choosing the Right Material for Your Needs

Your choice of baselayer material will depend on several factors, including:

  • Weather Conditions: Cold-weather hikes may call for Merino wool, while synthetic fabrics work well in wet or humid climates.
  • Hike Duration: For multi-day hikes, odour-resistant materials like Merino wool or bamboo are beneficial.
  • Budget: Synthetics offer a budget-friendly option, while natural fibres like Merino wool or silk are more premium.
  • Activity Level: High-intensity hikes may require highly breathable and moisture-wicking fabrics.

Care Tips for Your Hiking Baselayers

To extend the lifespan of your baselayers:

  • Follow the washing instructions on the label.
  • Use mild detergents, especially for natural fibres like Merino wool.
  • Avoid high heat when drying to prevent shrinkage or damage.
  • Store them in a dry, cool place to avoid odour buildup.

All in all…

Choosing the best material for your hiking baselayer is a personal decision that depends on your specific needs and preferences. Whether you prioritise warmth, moisture management, or eco-friendliness, there’s a material out there to match your requirements. By investing in the right baselayer, you’ll set the foundation for a more enjoyable and comfortable hiking experience.
