Merino 250 Asym Bottom

Snow? Ice? Wind? Snowy, icy wind? No problem. With the Smartwool Merino 250 Asym Bottom, you don't need to worry about getting the chills because these baselayer bottoms stand up tall to freezing weather. The merino wool softly insulated your skin while still breathing and wicking moisture. To add to the comfort, these pants also have a wide waistband to fit well and decrease bulk when layered. Flatlock seams also prevent chafing, so you can be at your most comfortable when you're outside.

So warm!

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

Overall a great baselayer for skiing. I'm always cold, but with these I stay toasty warm. They seem to run a little bit big, so maybe size down if you like a slightly more snug fit.

Toasty warm

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size
  • Size Bought: small
  • Height: 5'6"
  • Weight: 120lbs

I picked up a pair of these for ski touring and they're perfect. Not too bulky, warm enough on cold mornings, but not too warm that I die of sweat on the hikes. Will most likely use them for running too!

You honestly can't really go wrong with Smartwool. These merino bottoms are super soft and warm. They are perfect to wear under your ski/snowboard pants and are even slim enough to wear under jeans on those super chilly days. I would definitely recommend this base-layer if you want to stay warm this winter.

Bordeaux color is a little darker

  • Familiarity: I gave it as a gift but have feedback to share
  • Fit: True to size
  • Size Bought: M

This baselayer is awesome! The fit is so comfortable, and the material is great. They are warm, and a heavyweight layer without being too bulky. You can easily wear these under snowboarding gear without feeling like you have too many layers on. They are also full length, and reach all the way to my ankles. I got the Bordeaux color, and the color came a little darker than what was on the website, but they are still really cute. I would definitely recommend these.
