My outer layer is usually a house.

Merino wool base layering has changed my life.

One of the best bits of layering advice I got is about outer shells. If you're hiking and comfortable in your base+mid layers, and you have to put on the outer shell because of rain, make sure to remove the mid-layer or you will overheat. Amazing how well a base layer + outer shell can work when you're active.

Two things I really love: softshell fleece vests and base layers with thumb loops.  Softshell vests still block some wind, but let you vent heat from your armpits while keeping your core warm.  Base layers with thumb loops don't ride up when you put a shirt/sweater/jacket/etc. over them, and they keep the sleeves put when you're roaming about in snow.  I absolutely hate that 2-3" gap you get between gloves and sleeves sometimes.

Well done. You are the only outdoor/camping  YouTuber to mention live plucking of down. So many people promoting cheap Chinese bags/quilts. And even the certified stuff is not really trustworthy. Farms only checked once a year with it being an arranged visit. I bought a cumulus quilt, I trust the poles more and it's a smaller industry.
More needs to be done to raise this awareness

Great vid!  As a Brit, my waterproofs live at the top of my pack, not the bottom!  😉

If you gonna be working, like hiking with a backpack, just use brynje base layer and a windproof on top, like gore tex. If you stop for a break or will be stationary a bit just throw on a good wool sweater. Love from Norway!

A key point is that air pockets between layers are really important for staying warm when sitting still. The warm midlayer should not fit tight into the base layer. It allows for a better barrier between the heat your body are generating. You wannna percerve every little amount of heat when not moving.

"This is the closest thing I own to a suit" 😂👌

Wool. WOAL! I do want to say something interesting about polypropylene... I used to wear a black polypropylene shirt every day doing landscaping. I was made fun of because everyone thought white made more sense. They wore white cotton shirts then... They got sunburned because they translated the light through the clear/white fibers and then also did not dry very quickly at all. Then the wet clothing (covered in dirt) would irritate you until your skin bled. I could pour water down my back with a black polypropylene shirt and be dry so fast that it cooled me off. I also saved my skin from the sun. Some of the things that I learned were counterintuitive, like when I watched the landscaping teams that would use long sleeve shirts even in the sun. Of course that makes sense in a long term but it took a while to figure out why they liked to sweat that much! Lol.

Today it's 27° in Denver and I have a wool skull cap under my hard hat with a down bubble jacket and I use a high quality raincoat as a wind layer. There is a long sleeve flannel underneath that. My boots are insulated and have composite toe caps instead of steel to translate less cold to my feet. I use a cheap cotton long sleeve shirt under the flannel. I have a polypropylene short sleeve shirt under that. I also wear a gator around my neck made of stretchy cheap material. It needs to block the low speed wind only. It's a key to this temperature in my opinion. I have other layers with me and I take them off and put them on often to remediate sweat (like another thicker skull cap made of thick woven wool). In negative temperature I feel too hot. This system is tested every day.

Many years ago I added a thin vest/windbreaker to the mix  (the kind made for runners without arms and with breathable backs to compensate for the backpack). This is a game-changer. While active, it is often all I need over my base layer and leads to a less sweaty back and chest.
It is also suitable as a light mid-layer while wearing an outer shell and a base layer. They are usually relatively cheap, lightweight and versatile.

A saviour for newbies like me ,much needed, thanks Sensei

You cover a really important point in that you can layer up base layers ,ive not seen many other people discussing base layers cover this , so thanks for that

The best hiking gear and guides channel there is. No question, best of all of youtube mate.

At 80 my body is pretty beat up.  I'm now limited to biking.  On a winter ride  below freezing  0C - 32F,   over my inner layer I wear a tight wind proof weave wool pullover shirt that covers my butt, that I designed in 1973. I wear the shirt on the outside, untucked.  The base layer wicks moisture away from my core and the heat is trapped, and the moisture can exit through the bottom. My neck is protected by the stand up collar.  The shirt also has a 6 inch open at the neck that can open to exhaust excess heat.  I have switched to a poly wool blend base layer, since I can no longer find fish nest in the States.  I have become a big fan of alpaca,  socks, sweater, head cover. The alpaca wool  is antibacterial, the fibers are hollow and keep you cool or warm depending on the temperature. Since first writing this 8 months ago I have found a source for Fishnet base layer. It is Brynje USA The original fishnet from Sweden also Brynje Canada and Sweden.

Comon Chase be real with us, you didn't get the Salewa mid because it was cheap. You got it because it's the most banging mountain drip 🔥🔥🔥 nice video ❤️

As a person that sweats profusely,  even in -30c while workingbout doors. Wool with no shell is the only way to go.

Well, that was the BEST Winter Layering Video I've seen. Now I don't have to post one. I'll just share. 😁Thank you!

Watching this from my London flat preparing for winter 2022.

We had a -50° morning here in CT about a year ago. I went out in the -40° part of it. Helly Hanson thermals. Long sleeve and jeans. Goretex gloves with insulator underneath. DSG 3 in 1 winter jacket. Klein goggles vents closed. Lower face baclava. Big Bobby winter boots with wool thermal socks. And the snow pants. I did not feel any cold at all and sat on the porch for 20 minutes.
