Best Active Midlayer: Smartwool Smartloft Hybrid Jacket

Movement is key in the mountains. The problem with a puffy is that it restricts movement. Smartwool has wool in all the right places, and just enough synthetic stretch in the other spots to allow unrestricted movement. The jacket can stand on its own without a shell, with a chest pocket and hip pockets to stash some items or warm your hands if needed. It looks good in town as well as under a jacket, and provides the right amount of stretch to let you cruise without noticing it.

Note: There is a new model updated this year, I tested last year’s model. Not too many changes to report.

Best Synthetic Hoody: Jones Dark Start Recycled Hoodie

The Dark Start is a rite of passage to many who tour. Once the idea of starting before sunrise excites you rather than fills you with dread, you know you’ve moved into the echelon of downright crazy enough to earn the beauty of an alpine sunrise. I’ve been wearing this jacket for three seasons, and it always impresses me just how warm it is for being a jacket filled with recycled plastic.

The Air Flake insulation is no joke, though. It really works, and unlike down, it’ll work when wet. I’ve used it on its own too, and it does a decent (not perfect) job of wind protection. The highlight to these are the two internal dump pockets which keep skins warm since it’s staying close to the body. And the whole package packs into itself pretty neatly as well.

Best Down Midlayer: Rab Microlight Alpine Jacket

Yes, down loses its warmth when wet, but the hydrophobic coating on this jacket keeps it from being a total disaster. I wouldn’t trust it in a downpour, but simple moisture and sweat actually isn’t a total dealbreaker here. And the slim profile to warmth ratio has this jacket earning its keep for how light it is.

Best Fleece Midlayer: Patagonia R1 Jacket

Sometimes all-synthetic without the fluff is the go. I’m not a huge polyester fan, but there’s a reason that companies flock to it for a material. It’s warm, lightweight, and water-resistant. Add in Patagonia’s legendary repair policy and commitment to using recycled materials, and you get the reason for including it here.

Note: The model I tested is a few years old now. The new version has a chest pocket and does not have solid arms, adding for more breathability. My biggest complaint was the arms getting sweaty, so it’s nice to see they have changed that aspect of the jacket. Specs for the new jacket are listed below.

How to Choose a Midlayer for Skiing and Splitboarding

Bulk: will it fit under your shell? A midlayer only works if your shell still closes over it and you can still have unobstructed movement. Try it on under the jacket you already own. Grid fleece and stretch hybrids slide under almost anything; lofty puffies take up room and compress under a snug shell. If you’re shopping for both, read my hardshell roundup with this in mind.

Material: wool, synthetic, down, or fleece: Each one trades warmth, breathability, and wet-weather performance differently. Fleece breathes best and shrugs off sweat but blocks little wind. Synthetic insulation keeps some warmth when damp. Down is the warmest for its weight but loses loft when it gets wet, even with a hydrophobic treatment. Wool blends sit in the middle and resist odour on multi-day trips, but add weight when they get wet.

Does it work on its own? On the skin track you’ll often strip down to base and midlayer. Choose a face fabric that blocks a bit of wind and a cut you’d actually wear for aprés or on dog walks, if you want to maximise the value.

Pockets: A chest pocket for your phone or skins-off snack and hand pockets that sit above a hip belt are worth more than a long feature list. Internal drop pockets are handy for warming gloves or skins on cold transitions.

Weather resistance: No midlayer is waterproof, and it shouldn’t be. If it can’t breathe, you’ll soak it from the inside. A DWR finish helps a midlayer shed light snow when you’re skinning without a shell. Leave the waterproofing to the hardshell or you’ll prevent heat from escaping while hiking or skinning.

Getting it on and off: Swapping layers at transitions is the norm, especially in the springtime. A full zip makes this much easier, and will save time in the long run. Cuffs with thumb loops will also help keep snow out where you don’t want it.

Start with what you have: If you’re new to touring, the fleece already in your closet is a fine first midlayer. Upgrade once you know whether you run hot on the skin track or cold on transitions, because that tells you which material to buy.

Frequently Asked Questions

Is a fleece or a puffy better as a midlayer for skiing?

For uphill effort, fleece usually wins because it breathes and handles sweat. A puffy is warmer for its weight, so many tourers wear fleece while moving and pull a puffy on at transitions and on cold descents.

Can I wear a down jacket as a midlayer under my shell?

Yes, on cold, dry days or at the resort. On high-output days, sweat can dampen down from the inside, so a synthetic or wool layer is the more forgiving choice in wet coastal snow.

Do I need a midlayer for backcountry skiing or splitboarding?

Most days, yes. A base layer alone rarely holds enough heat on a windy ridge or a long descent, and a midlayer gives you a warm, breathable option between your base and your shell. Shells aren’t insulated, so you’ll want something that regulates heat well to get you into the sweet spot.

Is merino wool good for a midlayer?

Wool stays warm when damp and resists odour, which helps on multi-day trips. Pure wool is slower to dry and less stretchy, which is why many midlayers blend it with synthetics.

Should my midlayer have a hood?

A hood adds a lot of warmth for very little weight, especially under a helmet on cold descents. If you already run a hooded baselayer or shell, a hoodless midlayer avoids a pile-up of hoods around your neck.

The Final Word

All of these midlayers will help you stay warm in the mountains, and can even work on their own when you don’t need to layer up so hard. But put in combo with a good baselayer and shell and you’ll be having fun without fear of getting too cold. Just be sure to stay hydrated.
