My new favorite! Thick and

"My new favorite! Thick and cozy."

Sean P. (5/5)

As Good as I Hoped

"Quality product, warm and perfect fit. Is great over a thermal and/or under a jacket so works well for layering also. So all-in-all, I am very happy with this purchase."

Rocket (5/5)

Very soft and warm

"It is very comfortable and soft on the skin. Does exactly what it says on the tin - keeps you warm in very cold conditions."

Mango (5/5)

Icebreaker 300 top

"Good quality clothing, fast delivery, warm and cosy"

Al (5/5)

Excellent product

"Good weight fabric and incredibly soft. Almost silk like feeling against the skin. Very comfortable and warm so far and looking forward to seeing how well it performs over time. Really impressed so far."

D (5/5)

Solid Base Layer

"I was really looking for a heavy base layer and purchased these top & bottoms immediately. The quality is still obvious. Warm, but still breathable, the Size medium is just a bit snug on my 6'0"" frame but still fine. I just completed a cold weather exercise the military where it was -15C to -23C. This is what I wore all weekend."

Sarge (5/5)

Warm but quality control issue

"Use it for cold weather hiking and biking. It is warm and cozy. The zipper does not work properly as I need to twitch it left/right along the upper end to make it zip all the way. The zipper is anything but smooth as the other icebreaker items including a cardigan are, that i own. For a size large it needs to be longer to work optimal as an undershirt. The material is superb."

Portalite (4/5)

Enfin la bonne épaisseur 300 pour les sorties à-25 degrés .

"Enfin la bonne épaisseur 300 pour les courses à -25 degrés celsius. Je le porte avec une veste hybride icebreaker. Combinaison parfaite . Chaud, respirant, doux, confortable . Je mesure 6p 2po pèse 220 lbs taille 35 et le xl est parfait"

Pop (5/5)

Disappointing for a 300

"Having other 300 and for the price. . . This is just a glorified 260. I think this is as far as my run with icebreaker will go."

Lu C. (1/5)

Loyal icebreaker user for years

"I wear icebreaker everyday but love it especially for my remote arctic whitewater paddling trips. Never fails, always warm, fast drying and comfortable. Love icebreaker ??"
