    Merino 150 Baselayer

    Whether you're doing some spring skiing or summer camping, the Smartwool Men's Merino 150 Baselayer ensures your activity's done in elevated comfort thanks to the body temp regulating and stink-free properties of merino wool. One of SmartWool's lightest and most versatile base layers, this piece uses Core Spun technology, which wraps the merino wool around a nylon core for added durability without sacrificing the comfort of ultra-soft Merino next to your skin. It also features smooth, flatlock seams for chafe-free performance under the straps of your pack, and is designed to fight off funky odors after a particularly demanding adventure.

    • Baselayer for lightweight performance in cool or warm temps
    • Merino insulates, wicks moisture, and naturally inhibits odor
    • Slim fit clings for top-tier performance
    • Shoulder panels eliminate top shoulder seams for comfort under straps
    • Flatlock seams go easy on your skin

      Quality, but not slim for a base layer

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

      It's a great quality shirt, but if you are slim it's not going to be 'next to skin' like you would probably want for a base layer. I'm slim with an athletic build and the medium is baggy on me. Like other Smartwool shirts, the length is generous (just keep it out of the dryer)

      Go-to Baselayer

      • Familiarity: I've put it through the wringer
      • Fit: Runs large
      • Size Bought: M

      This has become my go-to baselayer. My main activity is hiking.

      Just the right weight

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

      Perfect for slumming around town or going on a run. Has a nice thin feel that works as a layer or by itself without looking too technical. Doesn’t feel like wool as a 250 weight does, more like a T-shirt. Leaves odor behind so you can wear repeatedly without washing even after sweating (not kidding, my wife does not tolerate smells).

        Great

          Fits a bit loose for a base layer but once I wash I'm expecting a touch of shrinkage. Warm, looks nice, and comfy

          All around best base layer

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

          This layer is wonderful for all kinds of weather. I have worn it on technical climbs in Alaska and the tetons, as well as backpacking in the summer heat to hide from the sun. It literally works everywhere as a strong versatile base. Super comfortable and fits really well. wicks all moisture and keeps you dry and stink free for days.

          My Go-to base layer

          • Familiarity: I've put it through the wringer

          This thing is on for just about every activity I do in the winter.

          How to Measure:
          For best results, take measurements over your underwear.
          Chest:
          Measure under your arms, around fullest part of chest and back circumference.
          Waist:
          Measure around your natural waistline, keeping the tape a bit loose.
          Hip:
          Stand with feet together and measure around the fullest part of the hip.
          Arm Length:
          With elbow bent slightly, measure from center back of neck, across top of shoulder, to elbow and down to wrist bone.
          Inseam:
          Measure along inside leg from crotch to ankle bone. Or using pants that fit well, measure the crotch seam to the bottom of the leg.
