    A Used Baselayer???

    • Familiarity: I returned this product before using it

    Very frustrating experience with Backcountry. They charged me the full new price for a "Worn Wear" base layer with holes in the seams. First, I am all for gear recycling. I think it's a great idea to reduce waste. But, I don't think a base layer should be recycled. Anything that has a trap door for quick access to your junk to take a leak in the wild should only be sold as new. More importantly, I think it's wrong for Backcountry to charge new pricing on "worn wear." I don't believe that was Patagonia's intent when they started the Worn Wear program. Picture attached. I could only attach 1 photo, so included the one with the holes vs. of the "Worn Wear" tag.

    A Used Baselayer???

    Turn up the heat!

      If you are looking for a warm base layer, these are great! I feel that these breathe pretty well with the design, but still provide the warmth that you need. I wear a 32 pant, and the mediums fit fine, but are slightly baggy in the crotch. This isn’t a huge takeaway though, as I would probably stick with the mediums no matter what.

      VERY Warm Baselayer

      • Familiarity: I've put it through the wringer
      • Fit: True to size
      • Size Bought: small
      • Height: 5'7"
      • Weight: 135lbs

      Great for any and all outdoor activity in cold weather. If I'm looking at temperatures below 20 degrees I put these on first and never get cold. Great for walking, snowshoeing, skiing, ice skating, you name it. Also great to sleep in on cold nights.

      Dad approved!

      • Familiarity: I gave it as a gift but have feedback to share
      • Fit: True to size
      • Height: 5'11"
      • Weight: 145lbs

      Bought these for my dad who is currently living through the gnarliest, snowiest and coldest winter ever in Bend OR and he is obsessed with this baselayer. He wears it all the time and LOVES how thin the base layer is but how it really packs the heat. ( I have womens version of these and I totally agree!)

      He is 6'2'' and about 210lbs and the large fits him well as a nice form fit.

      Cheap Waistband

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

      Fairly warm, but would not goes as far as to describe them as "furnace-like warmth". Writing the review mainly due to my disappointment with the waistband. For as expensive as these are, I'd expect a waistband that didn't bunch. After wearing these with the waistband bunched, it seems the waistband is now permanently deformed. I had the same issue with a pair of Patagonia underwear. It's crazy to me that cheap underwear can get a waistband right, but Patagonia can't. Complaining about a waistband might seem "nit picky", but once the waistband gets deformed, these bottoms are uncomfortable to wear.

      I've previously purchased the top counterpart to these bottoms and would highly recommend the tops.

      Perfect layer for under PowSlayer bibs

      • Familiarity: I've used it several times
      • Fit: True to size
      • Size Bought: Medium
      • Height: 6'1"
      • Weight: 168lbs

      These are the only layer I wear under my PowSlayer bibs, they are plenty warm on cold dawn patrols and not too hot when it warms up.

      Lightweight Warmth for Cold Days

      • Familiarity: I've used it several times
      • Fit: True to size
      • Size Bought: Medium
      • Height: 5'7"
      • Weight: 170lbs

      One of the best baselayers I have ever owned. Not only is the inside comfy but it is so warm. When I first put this on, I immediately noticed it trapping heat and warming me up, but it also breathes enough that I can leave it on and not suffocate in a sauna. I can wear these under my un-insulated ski pants and stay warm without trouble. I typically wear mediums and this was no exception. It fit great. It has a slim snug fit but with out being to form-fitting or revealing. These keep me warm without being too bulky and on frosty days, I can wear them under a pair of pants to stay warm and comfy. My new go-to baselayer.

      Now Dad Won't Ever Leave The House.

      • Height: 5'9"
      • Weight: 140lbs

      My dad is a bit of a baselayer connoisseur, and the Capilene Thermal Weights passed his test with flying colors. He's a tall dude at around 6'5" and 185lbs, and the XL was a great fit for him--long enough in the legs and sleeves without being too baggy. Unfortunately, his wife and I also got him the one-piece suit for lounging around, and we're entirely convinced he won't ever leave the house again. Yep, they're that cozy.

      Good for Apres ski

        Great everyday long underwear for skiing or snowboarding. These are the best long underwear that I have ever owned. They have a looser fit than traditional long underwear. The thermal weight Capilene has the perfect amount of insulation and breathability. The only time I would wear anything heavier than this would be a -20 degree day.


        • Familiarity: I've used it once or twice and have initial impressions
        • Fit: True to size
        • Size Bought: Medium
        • Height: 5'11"
        • Weight: 150lbs

        Mostly was looking for a base layer under my ski pants, so haven't used them yet, but looking forward to using them. They are very comfy and seem very warm, stoked for ski season to start!

        Sizing is the bane

        • Familiarity: I've put it through the wringer
        • Fit: Runs large
        • Size Bought: XL
        • Height: 6'3"
        • Weight: 200lbs

        I wear XL bottoms. Football legs and etc. Bought an XL Arcteryx Phase SV, and could not fit into them. Too tight.

        These Pagatonia Thermal in XL, however, are somewhat uncomfortably loose. Should've got an L.

        The insulation of the bottoms is interlaced, one line of substantial fleece and one line of next-to-nothing-thin face fabric. It doesn't seem to have affected warmth in the most significant way though. Would just feel a little weird around the knees if you are sensitive to it.

        This particular weave, however, will leave lines of red marks on your skin after exertions, and sometimes they itch.

        Bottoms dry moderately fast, and provide mid-weight warmth instead of the heavy-weight warmth its name might imply.

        Craftsmanship is the highlight. Durable. Design has good attention to details.

        Comfortable and Warm!

        • Familiarity: I gave it as a gift but have feedback to share
        • Fit: True to size
        • Size Bought: Small
        • Height: 5'8"
        • Weight: 145lbs

        Gave these to my dad! This is his review: "I have several sets of medium and heavy weight synthetic fiber long johns. So i was a little skeptical when the Patagonia Capilene Thermal Weight set arrived. They seemed a little flimsy and light. WRONG! They are the warmest, most comfortable set I have ever owned! I'm ordering another set and throwing all the others away".

        I think it's safe to say he liked them.

        From Loungin to Lift Laps n' Skin Tracks

        • Familiarity: I've put it through the wringer
        • Fit: True to size
        • Size Bought: Small
        • Height: 5'8"
        • Weight: 145lbs

        First of all, let me thank Patagonia and for selecting me to test and review the Capilene Thermal Weight bottoms.

        I was really excited to get my hands on these and see what improvements Patagonia made with their new line of base layers. I've been using an old pair of Patagonia base layer bottoms for the last 3 ski seasons and I love them. In fact, it's really the only base layer bottom I've used and needless to say, they are showing signs of wear. With these it was no surprise to find that Patagonia has made an already awesome product into something better.

        The fit is spot on for me and the cut is just so comfortable. I lounge around the house in these, sleep in them while camping, and of course use these for skiing/snowboarding and any other cold weather activity. Just the perfect all around bottoms. The fabric is so cozy with the interior being fleece (just like the Thermal Weight Top and it does an outstanding job of breathing to regulate body temp. I have not once over-heated in these babies no matter the activity.

        I think the only thing I would like is for them to fit a little more snug but this is more of a personal preference. Overall, these do what they are suppose to and do it well. Even when the temps are in the single digits, these keep me warm on any adventure. A great product and will certainly be in my closet for many years.

        The love and hate them

        • Familiarity: I've used it once or twice and have initial impressions
        • Size Bought: medium
        • Height: 6'
        • Weight: 160lbs

        The Good: Very warm and comfortable even in below freezing temps in the back country, I wouldn't hesitate to wear these when I go on my snow outing for search and rescue later this year. My recent outing was below freezing 26f and windy(I know this isn't cold to some, but in a stop-go-stop go with lots of "hurry up and wait" work environment 26f will get to you) this kept my legs comfortably warm.
        They dry quick enough, much better than old school non-grid fleece,
        Polygiene does work well and sets Patagonia apart from other grid-fleece base layers. This is the reason why I prefer patagonia.

        The Bad: " has a smooth face for easy layering" isn't all that true with these, it will still "grab" your mid-layer if it isn't slick.inside. I would not recommend for non-stretchy pants. The material waive is subject to "runs" (think pantyhose runs) (-½ star)
        Patagonia decided to add extra advertising to the waistband, men's underwear are already billboards with the company's logo or name all over them as it is so I generally discourage this in my ratings, the Patagonia capilene thermal weight isn't too bad about this so I will leave it a smaller hit (-½ star)

        The ugly: This is were I have a bone to pick with Patagonia with their new capilene series. Patagonia has seemed to developed some serious inconsistency/ quality control issues in the last/sizing. Try buying 5 pairs of the same size and try each one on, they will all fit very differently! I purchase a size medium and when I got mine, they seemed to fit okay, but the waistband was for a size large pair. It didn't feel snug at all around my 33" waist but the rest was okay. Luckily I found out there was a local Patagonia store near me that was willing to exchange them. Tried on a pair there and was perfect, but was curious and tried another pair or the same size and weight and felt like a small-medium (really tight around my thighs). I did this with their mid-weights too, tried on a few pairs, they have the same issues too (.-1star)
        TL;DR the product fit should have a "Varies" option for these.

        Are these as thick as the R1 hoody grid material? I am concerned I might overheat if they are. I have the light and midweight Capilene leggings and love both so far but looking for something warmer for those really cold days with light to moderate activity. Thanks.


        This is basically a lighter version of the R1, i think you'll be psyched. It definitely has some good warmth when you have a layer on top of it, and then it breathes really well when it's on it's own.

        To echo what Ty said, these are the warmest in the line and a replacement for the old expedition weight capilene. For reference these would be great for a cold day skiing the resort, too warm for me touring, and a great legging for winter running. Let me know if you have any other questions on this or other Patagonia items.
