Icebreaker Nature/Beast 150 Sweetheart Shirt - Merino Wool, Lightweight, Long Sleeve (For Women)

This is the second shirt I've gotten from Icebreaker, and they are both fantastic. The sweetheart shirt is thin, but really comfortable. I've worn this top hiking in 90 degree weather, I've worn it running in 40 degree weather, and it never gets stinky like polyester. I've even fallen asleep in it, it's so comfortable. I think these tops are better than smartwool, since they're more fashionable, have a nice neckline, and prettier colors/designs. I own a medium and a small, and they fit similarly (I'm 5'4", 135 lbs, 34D). Great tops!

I have another light weight icebreaker that is super soft and comfy. This one is a little itchy and the fabric seems fragile - like it could easily get a hole in it.

I wore this shirt to yoga with a camisole underneath because it is a light color. I will primarily wear this under other shirts or vests. If it gets cold here this winter, I think I'll wear it frequently. It is lightweight, well made and a pretty color.

I use this as a baselayer in the winter under my work clothes, casual clothes and sports clothes. It's warmth to weight ratio is superb. It doesn't add bulk but takes the chill away. As with the quality merino wool products, it doesn't itch or retain odors. It washes well, fits true to size. I can't get enough of these merino wool garments!

What I like about this shirt is that it keeps me warm in cold weather without feeling too bulky, which is an asset for me when I've been out hiking for hours. I also wear this shirt underneath a blouse or thicker sweater at work, and I find that it keeps me warm as well because I work indoors.
