Merino wool neutralizes unpleasant odors by absorbing odour molecules into its fibers, making them less detectable by the human nose.
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.
icebreaker merino wool garments undergo special anti-shrinkage treatment, helping to resist deformation and pilling.
The thermo-regulation properties of merino wool adapt to your body and external conditions, so you can stay warm in the cold and cool in the heat.
Overall rating: 4.5 / 5 from 4 reviews.

"I’m between a small and medium and I see that I could have ordered a size small for a tighter fit (I ordered medium)."
— Kirby (4/5)
"This is a great weight:warm yet with icebreaker’s usual light touch. It’s a beautiful colour , a nice changé which goes with everything and is beautifully made. I’m generally a medium size but got a large as I like a looser fit in the mid layers. I’m looking forward to wear8ng this now that winter is nearly here. Another perfect piece from Icebreaker."
— Adri (5/5)
"I love my Merino Blend 300 Real Fleece Descender jacket. I would call it more of a sweater weight. I wear it with a goose down vest on the chilly fall mornings and evenings, haven’t tried it yet for cold winter temps. I love all the Real Fleece full zip jackets. I own 4 of them, light weight and warm."
