Why We Like the Merino 150 1/4-Zip Baselayer

The Merino 150 1/4-Zip Baselayer is comfortable as the star of the show or doing work behind the scenes. We throw it on as our lightweight, breathable top for summer missions on the trail, and we layer over it as a sweat-wicking base for mid-winter runs on fresh powder. Ethically sourced from New Zealand's merino sheep, the wool keeps us cozy and eco-friendly. With the wool fibers spun around a nylon core to increase durability, we know this baselayer can withstand any adventure. Merino wool naturally resists odor giving us worry-free repeated use, and the flatlock seams resist chafing providing us with a comfortable wear every time.

My Favorite LS Tee Shirt

[This review was collected as part of a promotion.] This long sleeve tee shirt has become my go to undershirt during cool/cold days when wearing long sleeve shirts. I also wear it alone when lounging around the house or if taking a walk or hike. The zip allows me to dump heat quickly if exercising. The fit is great and the wool just feels great against my skin. I'm 5'11" and 200 lbs. I wish they were cheaper as I'd own more of them.

Great as a baselayer or by itself. Love it.

[This review was collected as part of a promotion.] This lightweight 1/4 zip is perfect by itself or as a base layer. I feel like I won the sweepstakes every time I get a new Smartwool item nd this was no different. I love it.

I would not buy this product again.

[This review was collected as part of a promotion.] This is a paper thin wool base layer. The point of a base layer for me is warmth and I find my cotton base layer is substantially warmer than this product. I'm spending the extra money on wool thinking it is going to be even warmer than my affordable cotton base layer. They are nice looking and look like a quality product except the fabric is so thin you can see through it. I would not buy this product again. I may try one of there winter weight wool fabrics but after this experience, I have concerns even this one won't be thick enough to provide the warmth over and above your average cotton base layer. I was disappointed with the product and will be returning them. Thankfully the company does provide a postage paid return label. Seems like a good company, I'm only disappointed in the thickness of the product. Perhaps this product should be called ultra light weight summer base layer. Your probably asking....what is the point of a summer base layer? Exactly, I have no idea and this product seems to have no point.
