Winter Hiking Layers: The Basics

When it comes to hiking in the cold, layering is everything. The secret is to create a system of layers that traps warmth, manages moisture, and shields you from wind and snow—while giving you flexibility to remove and add layers as your body heats up or the weather shifts.

Here’s how I break it down:

Base Layer (Next to Skin)

Start with a base layer. This is what sits closest to your skin—think long-sleeve tops and full-length leggings that hug your body. The goal here? Trap warmth, wick away sweat, and avoid that clammy, cold feeling.

Skip cotton – once it gets wet, it stays wet, and that’s a recipe for discomfort (and potential danger). Instead, reach for merino wool or a synthetic blend that breathes and dries fast.

Some ideas for a solid base layer:

Merino wool long-sleeve shirt– breathable, warm, and not itchy like old-school wool.
Synthetic long-sleeve shirt– great for sweat-wicking and typically more budget-friendly.
Merino wool leggings– cozy, comfortable, and perfect under snow pants or skirts.
Fleece-lined or insulated leggings– an affordable alternative to merino wool leggings that provide the same level of comfort and moisture wicking properties.

Why do I rave about merino wool?

It’s natural and biodegradable (Mother Earth says thanks).
It pulls moisture away from your skin and still insulates—even if it gets a bit damp.
It keeps you warm in winter and cool in summer (no, really).
It’s soft, not scratchy—yes, even for sensitive skin.
It’s breathable, odor-resistant, and doesn’t feel bulky.

Mid Layer (Insulation)

Once your base is on, it’s time for the mid layer. The mid layer is your main source of warmth. Think of it as the cozy cocoon that traps heat your body generates. I like to play around with options here depending on how cold it is and what kind of hike I’m doing.

Good picks for your upper body:

A lightweight down or synthetic puffy jacket
A fleece pullover or zip-up
Another merino wool layer

For your bottom half, these work well:

Insulated ski pants (especially if they’re waterproof)
Puffy or insulated skirts — don’t knock it until you try it. Warm and stylish!
Fleece joggers or sweatpants that fit under your shell

Pick a mid layer that fits well under your jacket or outer shell. It should be easy to remove and stuff in your pack if you start to overheat. I always stash mine when climbing hills.

Quick Tip:

As you warm up or the weather shifts, peel off your mid layer to avoid getting sweaty. Staying dry is just as important as staying warm—wet clothes steal your body heat quickly, even with fancy fabrics!

Outer Layer (Shell)

The final piece is your weatherproof shell. This layer blocks out wind and keeps rain or snow from soaking through. Look for jackets and pants that are waterproof (or at least seriously water-resistant) and have a hood or high collar for extra protection.

It doesn’t need to be thick or insulated (your mid layer handles warmth)—but it does need to be water-resistant or waterproof.

Your shell should fit over all your other layers, but not be so loose that cold air sneaks in. Cuffs that tighten around boots and wrists are also a big help.

Top features to look for:

GORE-TEX or similar waterproof material
Adjustable hood and cuffs
Zippers or vents for airflow

Quick Tip:

On mild days, you may not need your shell the entire time, but it’s something I always bring—winter weather can shift fast. For pants, waterproof overpants (like Helly Hansen’s Aden Pants) are perfect over your base or mid layers, especially if you’re walking through snow or wet brush.

Extra Gear That Makes a Big Difference

The big three layers get most of the attention, but it’s the smaller pieces that often make the biggest difference in comfort.

Socks

Never underestimate good socks. That means wool, always, and never cotton. Wool socks keep your feet dry, warm, and blister-free, even on snow-dusted trails.

Smartwool and Darn Tough are both excellent (and yes, they’re worth the splurge). Thick, breathable wool socks keep your feet warm and dry without overheating. I also bring a dry pair in my pack—just in case.

Boots

Winter hiking boots should be waterproof and have enough room for thick socks to keep your feet warm and dry. Having dry feet could make the difference between a fun hike and a miserable and cold experience! Insulated boots are great for snowy trails, but on milder days, waterproof trail runners with gaiters might do the trick. Oboz Bridger Insulated boots are a personal favorite for snowy days.

Warm Hat + Backup Hat

Heat escapes from the top of your head quickly, and you’d be surprised how much of a difference this simple accessory can make. A wool beanie keeps your head and ears toasty (and the wind at bay). Fleece can be a great option as welI, even if it lacks the moisture wicking properties of wool. I always keep an extra one in my bag in case mine gets wet or sweaty. Bonus: hats take up almost no space.

Gloves or Mittens

This is a “know thyself” situation. If you tend to get cold hands easily, mittens are warmer. Gloves give you more dexterity. Either way, make sure they’re insulated and, ideally, touchscreen-compatible. On extra cold days, I layer liner gloves under mittens.

Neck Gaiter or Scarf

Wind can sneak in anywhere, but a neck gaiter, buff, or scarf keeps your neck and face protected. Pull it over your mouth when it’s windy, tuck it into your jacket to seal out drafts, or wear it as a headband. I like a fleece one for a deep cold or a lighter buff for mild days. Easy to pack, easy to adjust.

Eye Protection

Snow glare is real—especially on sunny winter days! Sunglasses with UV protection are always a must, but especially on sunny days. For strong wind or if you’re headed above treeline, ski goggles are worth stashing in your pack. I’ve only needed them a few times, but they were a game-changer when I did.

Extra Headgear

Sometimes a baseball cap is all you need if you get hot on the climb up. It helps keep the sun off your face and fits under a hood.

My Favorite Winter Hiking Clothes (Trail-Tested!)

I’ve tried a lot of gear, read a ton of reviews, and swapped tips with fellow hikers. Here are some standouts in my winter closet:

Base Layers

REI Merino Wool Top

Super warm and easy to layer. It’s held up well for me, though I spotted a few tiny holes after years of use. Itchy at first, but that fades. Worth it for the warmth.

Minus 33 Midweight Crew Top

I haven’t worn this one yet, but it’s been sitting in my cart forever. High-quality wool, great fit, and rave reviews.

REI Merino Wool 185 Leggings

These are cozy under ski pants or an insulated skirt. Some reviewers mention wear and tear over time, so handle gently.

REI Lightweight Tights

More affordable and easy to layer. Lightweight but surprisingly warm when paired with other items. Most reviews are positive.

Smartwool or Darn Tough Socks

Pricey, yes, but unbeatable for warmth and durability. I’ve used both brands, and I’ve noticed that Smartwool tends to be more fuzzy after washes and the heel wears out faster than my Darn Tough. However, both brands are high quality, comfortable, and will last you many, many miles.

Mid Layers

Patagonia Synchilla Quarter Snap Fleece

This fleece is my go-to for warmth and comfort. It’s a bit bulky to pack when things heat up, but I reach for it every winter.

Marmot Puffer Jacket

Long-lasting, warm, and packable. I do wish I’d gotten one with a hood—learn from my mistake!

Quilted Puffer Skirt

Adds so much warmth over leggings and looks cute. The side zipper and stretchy panels make it easy to move and layer.

North Face Fleece Joggers

Soft and versatile—great for hiking or lounging. They fit well over base layers and don’t lose shape.

Outer Layers

Outdoor Research cirque III pants

The Outdoor Research Cirque III pants are an awesome choice for winter hiking because they’re made with durable, stretchy fabric that moves with you. Whether you’re climbing steep trails, scrambling over rocks, or heading downhill, these pants give you the flexibility you need without feeling stiff. They’re built for serious mountain adventures, so you know they’ll hold up well in tough winter conditions.

RAB Women’s Downpour Jacket

Budget-friendly and protective, with solid ratings for comfort and mobility. Several color options for mixing up your outfit.

North Face Antora Jacket

Great option for wind and water protection. They run a bit small, so I recommend sizing up for easy layering.

Winter hiking is magical—sparkling snow, fewer crowds, peaceful trails. But it’s also a test of your gear and prep. Knowing what to wear winter hiking can be the difference between a memorable day outside and a miserable one.

Build your outfit around smart layering: moisture-wicking base, insulating mid, and weatherproof outer. Don’t skimp on the accessories like socks, gloves, and a warm hat. With the right layers, you’ll stay warm, dry, and ready to take on any trail—even when the temps are downright frosty.

If you’ve found a piece of gear you swear by, drop it in the comments—I love hearing what works for other winter adventurers!

Happy hiking, and I’ll see you out on the (snowy) trail!

The FAQ

Frequently Asked Questions

Not necessarily. The key is to dress in layers so you can adjust based on the weather and your activity level. Start with a moisture-wicking base layer to keep sweat off your skin. Add an insulating mid-layer if it’s cold, and top it off with a waterproof or windproof shell if there’s precipitation or strong wind. You might start your hike with all three layers but shed the mid-layer as you warm up, then put it back on during breaks to stay warm.

Merino wool and synthetic fibers like polyester are top choices. Merino wool is natural, breathable, and insulates even when damp. Synthetic materials are durable, wick moisture effectively, and dry quickly. Both are excellent for keeping you dry and warm during winter hikes.

Dress in layers that you can easily add or remove. Start your hike slightly cool, as your body will warm up with activity. If you start to sweat, remove a layer to regulate your temperature. Use ventilation features like pit zips on your jacket or unzip your outer layers to allow heat to escape. Staying dry is crucial, as wet clothing can lead to rapid heat loss.

Avoid cotton at all costs. Cotton retains moisture and loses its insulating properties when wet, increasing the risk of hypothermia. Instead, opt for moisture-wicking materials like merino wool or synthetic fabrics for your base layers. These materials keep you dry and maintain warmth even when damp.
