Customer Reviews Smartwool Merino 250 Base Layer Bottoms

Extra soft and warm. I highly recommend adding these to your winter wardrobe essentials to tackle anything and everything imaginable.

Cozy and comfortable during our recent blizzard and cold temps.

Needed a heavier base layer for those cold, gray winter days when the snow is not great so I'm skiing easy but have to be out all day. (I'm a Mountain Host at Jackson Hole.) This product is great - super soft right out of the box; snug comfortable fit and not at all bulky but noticeably thicker material than all my other base layer bottoms; and overall a very high-quality feel and appearance. Definitely keeps me warmer. Will be buying a top of the same fabric.

Another great first layer protector and warmth without being bulky.

These were a gift for my son. He has several pairs of smartwool "base layer bottoms"! loves them.

Comfortable, warm and odor free. Great for hanging out at home or out for a hike. Helped keep me warm in the mid teens.

Wore these for the first time skiing. They kept me warm for three days straight and remained fresh smelling.

Lifesaver in the Midwest winter! My Christmas gift to my brothers. Good fit, wears well and washes easily.

Best base layer bottom I have purchased to date....looks great, very warm and wicks away moisture....this bottom is the only one that I have found that does not cause my skin to itch...you don't even know you have them on...I do hand wash and lay flat to dry hoping to extend longevity....I'm going order another bottom and a top

Warm and lightweight. Used for first time skiing in below zero weather. Would recommend and buy again.

#sweepstakes This is the item I'm looking for! Really warm inside. It's really thin and warm. Really glad I find this brand and this product

This Baselayer fits perfect and has kept my legs warm while out in the cold

Thanks you smartwool for keeping me warm and comfortable without destroying my bank account!

Very nice knit and good fit.

Nice for layering

#sweepstakes Just used my new base layers skiing in zero degree temperatures and felt comfortable. This replaced another set from another company that has seen better days. I instantly wished I would have upgraded sooner, this is my new go to base layer.

These have been a lifesaver with the cold streak in NYC lately. I've been wearing these under my pants, and it keeps me totally comfortable outside (with a warm jacket of course).

As a professional arborist and use the Merino 250s for large tree climbing work. They are by far the best base layers I've ever worn. They are well constructed, smooth and soft against my skin and the fit is so comfortable that it feels like I'm not even wearing them. They are very warm and block the wind chill well without overheating. Excellent product. I highly recommend. ##sweepstakes

I gave them to my husband for Christmas and he wears them all the time.

Very warm and cozy. Use them for snow blowing and winter camping/hiking in NH. I would definitely recommend, a little pricey but awesome.

These are awesome! They keep you warm when standing still then regulate breath well during high activity while keeping you dry and comfortable.

My husband loves these! The fit and quality are great.

I use it all day all week in office

I have zero complaints about this product. They are soft and extremely warm all while staying extremely light weight. Looking forward to buy the 150 model when it's cooler out.

Perfect. High quality, super comfortable, and great fit.
