I had been looking at this jacket for about a year. It is soft and comfortable and stylish enough to wear around town. Where it really shines is in cooler weather exercise. I have used it running and hiking and it is great at cutting the wind but not making me too hot. Breathable, comfortable, and a... Read More

    best base layer, smart wool makes the stuff you want against your skin when it is going to be there for a long time in the cold and your body is working hard
  • Verified Buyer Reviewed by MCATCT from New England on Wednesday, December 3, 2014
    Used this sweater with lightweight wool t-shirt to ride my bike in 40F temp. Worked great, not completely windproof but blocked the wind enough without being chilled and kept me warm enough without overheating.Very well made, fits well and I like how the collar can be folded down. This jacket will get a lot of use-casual and active. I'm 5'8" and a fit 170lbs the medium fits perfectly, except it's slightly long, but that is the case with most jackets since I'm shorter than average.

    Overall, I am pretty satisfied with this top layer. The fabric used for this top layer is a wool and synthetic blend and as I expected, I get the advantages of both. It feels just a bit bigger than expected, but thats my personal experience. I usually get good fit with size M athletic apparels, but this one feels just a tad big, but its within tolerable limits. This does not exactly fit into my defination for a base layer even for a winter wear. This could work as a medium layer or even top layer on less chilly days for people with active lifestyle. Very good warmth to weight ratio, in my opinion.

    I needed a new base layer for snowshoeing and snow camping and decided to go with wool instead of a synthetic material. I wanted to test out wool's natural wicking and temperature regulating abilities. Also the odor resistant nature of wool was a big plus. Who wants to smell? This garment is double jersey knit so it actually feels more like a tee shirt than a wool sweater. I am very impressed with the craftsmanship and thoughtfulness of the design. I am six foot two and weigh 260 and this fits really well. I do wish it had articulated elbows, but it still provides ample coverage while engaged in normal winter activities. The only time it rides up is when I fully extend my arms up. So it might cause issues if you are ice climbing.

    This is base layer is worth the price. It may be slightly heavy (but what do you expect from a good base layer for winter conditions?), but it is phenomenal in temperature regulating. It also has a full zip (underneath I wear a compression shirt) and 5 pockets. I am also allergic to lanolin (wool fat) and usually can't stand wool, but SmartWool says this is itch free. Truth be told I am still a little itchy, but it is completely tolerable and so worth it. I cannot wait to test this out in a snow cave in a few months.
