Layering tips from 15 backcountry guides in 2023-2024 | What to wear and how to wear it? Layering tips from the peak season to the spring season

In the snowy mountains, bad weather and the risk of hypothermia are always close by. You may be hit by a sudden snowstorm, or in the spring mountains, you may be forced to hike up for long periods under the intense sunlight. Even in such harsh natural conditions, backcountry guides must act appropriately while ensuring the safety of their guests. To do this, it is important to stay in perfect condition so you can move around freely. Clothing plays a major role in regulating body temperature. We asked professional guides what kind of layering they use in the mountains and what their impressions are

Telemark School & Ski Guide Izumiya AK.T | Kenichi Akutsu

Original styles tailored to the unique situations of Minamiaizu

High season layering

Outer layer: SCOTT Explorer 3L Jacket & Pants;
Middle layer: Patagonia R1 Pullover Hoody;
Base layer: Patagonia Men's Capilene Midweight Crew

How does it feel to use? (Impressions)

The SCOTT Explorer 3L outerwear jacket and pants are a bestseller among SCOTT apparel. They offer excellent waterproofing and breathability, and there are plenty of convenient pockets for notebooks, smartphones, maps, and other items. Though made overseas, the sizing is similar to Japanese sizes. The price is also reasonable. The Patagonia R1 Pullover Hoody mid-layer is the thinnest fleece available, but pairing it with the base Capilene provides excellent warmth and moisture-wicking properties for hiking up steep Russell slopes in Oku-Aizu during the harsh winter

What about layering for spring?

Instead of an R1 Free mid-layer, I wear a Capilene Hoody as a base layer, with an even thinner layer of Capilene on top (March-April)

Are there any other ideas you have added?

During the harsh winter months, I carry a Patagonia Nano Air Hoody, and from March onwards, I carry a down vest

Rhythm Works (Rhythm Works) | Ryuta Asahi

Consider the characteristics of the area and altitude where you will be working, and choose a balance of warmth, moisture permeability, and breathability

High season layering

Outer layer: Patagonia Powslayer Jacket
Middle layer: Patagonia Nano Air Light Hybrid Hoody
Base layer: Patagonia Capilene Midweight Crew

How does it feel to use? (Impressions)

Consider the characteristics of the region and altitude where you will be active, and choose a jacket that balances warmth, breathability, and ventilation. For the 2023-2024 season, I changed my mid-layer to Patagonia Nano Air Hybrid. Taking into account humidity and temperature, this set allows heat to escape while hiking and keeps you from getting soaked with sweat. Because you will be active in dry, cold, and windy areas at high altitudes, inland areas, and high latitudes, I used Nano Air with Capilene Air, which prioritizes warmth and breathability

What about layering for spring?

Outer layer : Patagonia | Pluma Jacket
Middle layer : Patagonia | Nano Air Light Hybrid Jacket
Base layer : Patagonia | Capilene Cool Lightweight or carry Houdini Air as a midweight windshell

Kuroda Mountain Guide Office | Kuroda Makoto

Each layer is selected and adjusted to suit your movements on the snow

High season layering

Outer layer: Patagonia Houdini Jacket.
Middle layer: Patagonia Capilene Thermal Weight.
Base layer: Icebreaker 200 Series.

How does it feel to use? (Impressions)

When ascending, I wear a combination of Patagonia's Houdini Jacket, Capilene Thermal Weight, and Icebreaker undershirt. When it's cold, I wear a Micro Puff Vest on top. I always wear a hard shell, and to avoid overheating, I often use a thin soft shell like the Houdini Jacket. Hard shells are also economical because they last longer. I

often take off my shell and carry it, so it's important that it's light and compact. Another important thing about a shell is the shape of the hood. Does it ensure visibility and breathability in strong winds? Since I'm carrying a backpack on the mountain, the powder skirt on my hard shell isn't actually necessary, so I cut it off.

What about layering for spring?

I usually wear a lightweight Icebreaker wool T-shirt and a Patagonia Airshed Pro pullover. For day trips, I use softshell pants with a light rain jacket as a backup, and for overnight stays, I use Black Diamond Activeshell pants

Are there any other ideas you have added?

I pack my synthetic jacket in a convenient location so that I can put it on first during breaks

The secret to layering is not to be lazy

High season layering

Outer layer: klattermusen | Skirner Jacket/Skade 2.0 Salopette
Middle layer: klattermusen | Hodur Hooded Zip/Nal Vest
Base layer: klattermusen | Huge Crew/Hugin Pants

How does it feel to use? (Impressions)

The outer shell is a relaxed fit and the fabric is very soft, so it's comfortable to wear all day. For the mid-layer, I combine a hoodie-type fleece with a windshell vest. I often walk at the front, breaking through the snow, so I like the ability to make precise adjustments, such as taking off the fleece and putting on a vest over my base layer to avoid overheating.

I chose the over-down jacket in a size that can be worn over the outer shell. There are many days when I can't let go of my down jacket, from when I'm getting ready to ski, to when I'm already on the slopes, and right before starting the next climb. I recommend wearing a down jacket on the outside rather than under an outer shell, as it's easier and warmer.

What about layering for spring?

I changed the top of my base layer to a light wool one, but otherwise I'm using the same clothes as I did in the high season

Are there any other ideas you have added?

It's not a trick, but if you're hot, take off your clothes immediately, and if you're cold, put them on immediately. The trick to layering is not to be lazy. Once you've mastered that, the next step is to take off your clothes if you think you're going to get hot, and put on your clothes if you think you're going to get cold. If you're hiking in the mountains and are climbing a long, steep climb or a windy ridge, be sure to be conscious of observing and predicting the route and conditions a little ways ahead

Outer layer: unfudge | SMOKE ANORAK＆ PEEP BIB PANTS
Middle layer: unfudge | UN2100
Base layer: unfudge | UN1000・UN1050

How does it feel to use? (Impressions)

My favorite feature of the anorak is the large Doraemon pocket. The side zipper opens wide, providing excellent ventilation. The bib pants have excellent heat retention and convenient chest pockets. There are slits that allow you to reach your hands from the anorak into the bib pockets. The mid-layer has a grid design that provides both heat retention and breathability, and the hoodie allows for quick adjustments depending on the weather. The first layer also has a grid design that provides excellent heat retention, breathability, and comfort

What about layering for spring?

The outerwear will be soft shell type for both the top and bottom to be able to adapt to changes in temperature. If it looks like it might rain, a hard shell may also be used

Assuming you'll sweat, wear a base layer that provides minimal warmth and dries quickly

High season layering

Outer layer: Arc'teryx Alpha Jacket
Middle layer: Arc'teryx Proton Lightweight Hoody
Base layer: Arc'teryx Lo LT Hoody

How does it feel to use? (Impressions)

I don't want to get too cold from sweat, so my basic outfit consists of underwear, a mid-layer, and a shell. If it's cold, I'll wear synthetic insulation over the shell. I sweat a lot when treking in deep snow, so I need a quick-drying base layer, and a mid-layer that's both warm and breathable. I choose a shell that's soft and strong

What about layering for spring?

Since this is a season with large temperature fluctuations, there is no set layering, but I tend to use soft shells a lot

Are there any other ideas you have added?

When hiking, I assume I'll sweat, so I only wear the minimum amount of insulation. When I'm resting or when it gets cold, I wear the Arc'teryx Nuclei SV that's in my backpack

This will be a wonderful skiing experience

What about layering for spring?

The basic layering is as above, but each layer should be thin

High season layering

Outer layer: Arc'teryx Sabre SV Jacket + Sabre Pants
Middle layer: Arc'teryx Sabre Insulated Midlayer

The best thing about Arc'teryx is its style. The three-dimensional cut is excellent and does not hinder movement when skiing or hiking. It
keeps your body dry even in wet snow or rain, and it feels like a wearable shelter. It has excellent windproof performance and is comfortable even in blizzards.

Infield ｜Toyo Nakano

Use synthetic or wool base layers depending on the type of tour

High season layering

Outer layer: MOUNTAIN HARDWEAR | Boundary Ridge Gore-Tex Jacket & Bib
Middle layer: MOUNTAIN HARDWEAR | Core Air Shell Warm Jacket
Base layer: MOUNTAIN HARDWEAR | Air Mesh Hoody

How does it feel to use? (Impressions)

Since I'll be using it for many days, durability is a priority for my outerwear. In the harsh winter, pants have excellent heat retention, and I use bibs that prevent snow from getting in. For mid-layers, I prefer a model that keeps me warm but also allows sweat to escape, reducing the number of times I need to adjust my clothing. The padding is synthetic, so I don't have to worry too much about it getting wet.

For base layers, I use either synthetic or wool, depending on the type of tour. Air mesh hoodies combine the contradictory functions of fleece lining for warmth and mesh for breathability, and are my most frequently used piece of clothing these days.

What about layering for spring?

In early spring, temperatures are higher than in the depths of winter, so I use a thin outer layer and combine it with a model that is resistant to sweat and rain, but it's also important to be able to handle sudden drops in temperature

Are there any other ideas you have added?

I always carry a thin down jacket or wind shell that I can quickly put on when I take a break. Recently, there has been an increase in models that are good at wicking sweat, both for cold weather and wind protection, so I use those

Mountain Guide Coyote | Ryuta Furuichi　

I love this all-weather jacket because it's so comfortable when hiking

Middle layer: SALOMON｜OUTLINE DOWN JKT＋OUTLINE HZ MID M
Base layer: SALOMON｜SNTIAL WOOL LS TOP M(Top) SNTIAL WOOL SEAMLESS(Bottom)

Featuring Motion Fit™ patterning, this jacket adapts to your every movement, even on tough, technical slopes. It's a reliable piece built for rugged adventures. It's highly waterproof, yet breathable thanks to its GORE-TEX fabric. It offers exceptional peace of mind, even in the winter mountains. It's also durable and durable, even with heavy use. Four front pockets provide quick access to winter accessories like scrapers, ski bands, and passes, making it incredibly convenient.

These days, the OUTLINE HZ MID M midlayer is all I need. With the hood pulled over, wind and snow don't get around my neck, keeping me incredibly warm. I also always carry the OUTLINE DOWN JKT down jacket in my pack during the harsh winter months of January and February, as it's lightweight and compact. Simply throw it on over your shoulders during short breaks to conserve energy. It's warm and comfortable, making it the perfect way to unwind.

I use wool for my base layer because I absolutely hate getting cold during the snowy season. Even if I sweat a little, I don't feel cold at all.

What about layering for spring?

I wear a thin Salomon OUTLINE FZ HOODIE (thin fleece, Houdini) as an inner layer, and a thin, crinkly material in my backpack

Layering to keep you warm and keep pace with your guests

High season layering

Outer layer: Patagonia Powslayer Jacket.
Middle layer: Patagonia Nano Air Hoody.
Base layer: Patagonia Capilene Thermal Weight Zip Neck.

How does it feel to use? (Impressions)

When guiding, it's cold to match the pace of the guests, so I often wear layers that prioritize warmth. I'm sure everyone is concerned about the guide's layering, but this depends on individual differences, differences in physical strength, and differences in how you act based on experience, so I think most people would end up too hot if they tried to imitate the guide's layering

What about layering for spring?

Outer layer: Patagonia Powslayer Jacket.
Middle layer: Patagonia R1 Air Crew
. Patagonia Houdini Jacket.
Base layer: Patagonia Capilene Midweight Zip Neck.

The thing I always keep in mind is that it's warm enough

High season layering

Outer layer: NORRONA tamok pro jacket & pro big pants
Middle layer: NORRONA trollveggen Powerstretch Pro Zip Hood
Base layer: Smartwool Classic Thermal Merino base layer top and bottom

How does it feel to use? (Impressions)

When layering, I always keep in mind that my layers should be warm enough. I choose base layers that are warm, flexible, and comfortable enough that I want to wear them all the time. Personally, I prefer natural merino wool over synthetic fibers, and I've been using Smartwool base layers for over 10 years. I

also like flexible mid-layers, so I wear Power Stretch. I also really like hoods that fit like balaclavas. For shells, I prefer Gore-Tex Pro. For NORRONA, I use tamok and lofoten, and in the harsh winter I prioritize warmth with a long tamok jacket and bib pants.

What about layering for spring?

Outer layer: NORRONA | falketind Gore-Tex Paclite Jacket & lofoten Gore-Tex Pro Pants
Middle layer: NORRONA | trollveggen Powerstretch Pro Zip Hood
