"Icebreaker Merino is fantastic for its comfort and natural temperature regulation. It's soft against the skin, doesn't get smelly like synthetics, and keeps you warm in the cold yet cool in the heat. It's a versatile and high-performing choice for any adventure or everyday wear."
— Murka (5/5)
"Lightweight, soft, and comfortable, the Merino 150 Cami is the perfect undershirt for hiking. It also dries quickly."

"Fits to size described. Adjustable shoulder straps. Washes & wears well, feels comfortable, not at all itchy. Love it."

"Icebreaker has been making this cami forever. I know because I probably have bought it 5 times. But it used to be made with 175 level merino and now it’s 150. The 175 was better. Tighter weave held its shape etc. I still will wear this one a ton but would love it if they went back to making the 175 version which I can’t find anywhere."

"On the tiny, remote PNW island where I live, the offshore breezes can be chilling, even on the sunniest of days. This cami is super comfortable and gives me that extra touch of light warmth needed for those windy days. In fact, I wear it pretty much every day now, except for the rare days when we have over 75-degree heat. Additionally, the size chart said for my age group to buy a size XL, and I'm glad I did, because I don't like form-fitting garments. This XL fits my frame nicely without feeling tight OR too baggy. It fits 'just right. ' My regular size clothes are generally large or sometimes medium, depending on the brand. Considering how often I'll be wearing it, it's a good value."
