Great product

  • Familiarity: I've used it several times
  • Fit: True to size
  • Height: 5' 7"
    Weight: 150 lbs
    Size Purchased: Medium

I initially bought a large because I didn't want the fit to be too snug. It was way to big and exchanged them for a medium (Backcountry customer service is great, by the way). Fit, comfort and warmth are fine. I deducted one star because I don't like the feel of the waistband. It too rigid for me but that's probably a personal thing.

Love these, good fit

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size
  • Height: 5' 10"
    Weight: 220 lbs
    Size Purchased: X Large

I went with the XL on these as I'm ~5'10", 220 lbs, and I have "athletic" thighs and calves. These fit perfectly and allow me room to move easily in them while skiing. Too, I kept plenty warm with these on, a pair of sweats (if not using insulated ski pants), and ski pants.

Unanswered Question

My son is going to Scotland for a month for study abroad. He needs some sort of base layer. It will be in May when daytime temps are upper 50's to 60. He will be spending a lot of time outdoors. Of course at night the temps will dip down. Was looking at these Capilene vs. Merino Wool. He normally wears 31x34...long legs. Suggestions?

Do it all baselayer

  • Familiarity: I've put it through the wringer
  • Fit: Runs large
  • Height: 6' 2"
    Weight: 175 lbs
    Size Purchased: medium

I use this base layer for snowboarding, climbing, hiking and just a warm layer for under casual pants that I don't really have to take off....ever. These are breathable and moisture wicking with an antimicrobial coating so you can wear them for a few days of hard use without worrying about being asked to leave the room. Extremely comfortable fit. Relaxed long john style fit. Not a compression pant or form fit. I am 6'2'' 175 with a 32x32 pant size and the medium fits perfect so they do run a bit large. Enjoy!

Comfortable and warm baselayer.

Great base layer for cold days. I wouldn't wear them on days when the temperature is 40 degrees or higher.

Fit is a little big

  • Familiarity: I've used it several times
  • Fit: Runs large

These are a little longer and baggier than I would normally wear in a base layer. I wear a large in pretty much everything, but I should have gone medium in these. Otherwise they are great

Second Skin

  • Familiarity: I've used it several times
  • Fit: True to size

As I write this, I'm not quite sure I've taken these things off. The most comfortable baselayer i have ever worn. They're not the heaviest of layers, but that's what a midweight is for. I am 6' and usually wear a 32x32 pant, and these fit great.

The Midweight is still pretty thin.

  • Familiarity: I've used it several times
  • Fit: True to size

I expected the Midweight 3 to be much thicker. I am glad that it isn't.

When layering the Midweight is a perfect choice. I have some Heavyweight base layers from MHW which is overkill most of the time. I also have some Silkweight from EB. I don't really count the UnderArmour I have because it makes you feel cold. It is just weird stuff.

Patagonia's Capilene is hands down the best underwear out there. I was only using a pair of lightweight guide pants on Rainier and added these for our ascent of the mountain. It was the perfect combination even though it wasn't the best of conditions. We all looked like frosted donuts by the time we reached the summit. I was fine the entire time on my legs. I would have overheated if they would have been any heavier weight.

If I was looking for a set of underwear I would start with the Midweight Capilene and then get a heavier or lighter weight later.

The Midweight 3 is just so versatile when layering.

I am wondering if these would be too warm to wear with a pair of gore-tex pants? I will be snowboarding bowls and backcountry in -10 to 20 degree weather. Thanks!

Hey mmc105298538,

No, these shouldn't be too warm while wearing them with a pair of gore-tex pants.

Why is it when you see the top you want the bottoms arent the same color

Ha! I hate it when that happens.
What color/size are you looking for? Email me and I can check to see if we have them on order! Unfortunately it does look like Patagonia makes the top in way more colors than the bottoms, so obviously we are limited to what they produce.

Super soft, runs large

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: Runs large

I bought this to upgrade my older base layers. After-all, base layers are extremely important. They fit rather large compared to what I'm used to. I am 6'1, 185 and the Large fits pretty lose. Wish I would've gotten the Medium! Oh well, what can you do? They're comfortable and don't itch at all. Good buy. Remember to hang dry!

Best Answer

Generally I feel that merino wool is warmer than Capilene if we are talking oz for oz. However there are a variety of factors that go into what makes a Capilene or merino garment warm beyond the base material itself. While there are some hardcore aficionados that will only wear one kind of material, I tend to like merino for warmth when I need warmth above all else and my activity is not too strenuous, and prefer synthetic for higher intensity activity where breathability and mobility are more important.

Are these being discontinued? Why is only XL and XXL available?

More sizes should be in stock soon! Not being discontinued for sure.

Wonderfully Warm & Comfortable

  • Gender: Male
  • Familiarity: I've put it through the wringer
  • Fit: True to size

This is the second pair I have brought my son. He's a railroader working in all types of weather. He claims they are the best ever! Very comfortable, true to size, they don't shrink but most of all, keeps him warm in high winter winds with windchills below zero. He claims it's the best investment I've ever brought him. He claims he'll never buy anything else again. The service was great, delivery very fast. So glad I choose Backcountry, will continue to do business with them in the future.

Nice and warm

  • Familiarity: I've put it through the wringer
  • Fit: True to size

what is better than being warm and comfortable? Nothing. These bottoms provide you with that warmth and comfort when you are in cold and uncomfortable environments. I mostly use these Ice climbing to help stay warm at belays and I have used them running in the winter as well. they are perfect for both, a bit to warm for me to ski in unless its really cold. but the performance and durability cannot be beat
