Why choose icebreaker merino wool?

Natural odor resistance
Natural odor resistance

Merino wool neutralizes unpleasant odors by absorbing odour molecules into its fibers, making them less detectable by the human nose.

Moisture management
Moisture management

Merino fibers efficiently manage moisture, absorbing it from your skin and releasing it into the atmosphere. It can absorb up to 35% of its weight in water without feeling wet.

Machine washable
Machine washable

icebreaker merino wool garments undergo special anti-shrinkage treatment, helping to resist deformation and pilling.

Temperature regulation

Love the mock neck collar

"Nothing bad to say, material is wonderful, neckline is smoothe, color of murky purple is perfect. Plan to buy another."

— 567!@! (5/5)

Love this

"Great for cold winter hikes and snowshoeing. Very soft and excellent fit."

— Sada N. (5/5)

Soft comfortable and warm!

"I would definitely buy this shirt again, it is very soft, comfortable and warm when wearing by itself or with other icebreaker layering."

— Bri (5/5)

Flawless!

"So soft, so warm, so comfortable and so well-made. I've worn this on multi-day camping trips and can confirm it doesn't hold onto odors. The zipper is unobtrusive enough to stay comfortable and the sleeves fit whether or not I'm using the thumb holes. It washes and air dries so so well and keeps the perfect, steady body temperature. I'll be buying more for sure."

— Bee (5/5)

My new favourite top

"Incredibly soft, beautifully made top. I love the slightly lower but snug polo neck collar. Can we have more colours instead of just black ? Can we have more of this lower collar ?"
