Icebreaker  Merino 125 ZoneKnit Long-Sleeve Half-Zip Base Layer Top - Men's

[This review was collected as part of a promotion.] I already own the version without the raised collar and I love it. The "added turtle neck" is great for cold, windy days (running and cycling). I like that the collar has a snug fit (it doesn't let air in and it doesn't bunch up and fall down around your neck). I also like that the turtle neck is "full length/tall". The only thing is that the zipper in mine has a pinch point or some defect right when the turtle neck starts, so I can't zip it all the way through with one hand, which is very annoying when on the bike since I can't pedal without hands on the handlebar.

[This review was collected as part of a promotion.] I am a bit of a heater, so always on the lookout for lightweight, breathable workout gear - and this one hits that spot perfectly. It's lightweight for sure, but surprisingly robust. I've worn it down to 20 degrees and it kept me warm. Buying another one, which is probably the best recommendation I can give

[This review was collected as part of a promotion.] I am very easily irritated by the weather changes, so this sleeve Half Zip is great when I go to school or in the air condition area. I do not need to wear too heavy a Jacket, to keep warm in school, so I do not carry too heavy pack bags. On the whole wintertime, I wear this and one light jacket,

[This review was collected as part of a promotion.] I use this top (and it's IB predecessors) for over 12 years now, primarily for cross-country skiing. It provides the perfect balance of a light warm layer and perfect breathability for a highly active sport like XC skiing. Dries so quickly and is never cold/clammy.

I bought this shirt in the summer because it was on sale. I haven't worn it skiing yet, but I have worn it around the house, and the fabric feels great on my skin. Nice cut, good fit. I must say I love it.

[This review was collected as part of a promotion.] Love the color and soft feel of this product. I use it while skate skiing and it wicks the moisture away from my skin. It is the perfect light amount of insulation. Very sharp looking

[This review was collected as part of a promotion.] I was looking for a lightweight shirt for being out in the sun and this seems to be a perfect fit. Super happy with the shirt.

[This review was collected as part of a promotion.] Bright blue color is wonderful. Sleeves are at least 3 inches shorter than his older same style items.

[This review was collected as part of a promotion.] it just plain works, and it's not just for the winter, but great for high output in the winter.

[This review was collected as part of a promotion.] my only complaint is that sleeves do not seem as long as past versions.
