Great zip up
Great 100% merino zip up great for yoga class and will be perfect for ski season.
Recommend it
Perfect fit, great quality , price is better than rest for same material ( wool ) given the fact that after about 50 washes, it is still same shape & form...highly recommend it.... i always wish for more color availability, not patterns, just more colors
Thin shirt thickness for this "jacket"
This is a brown-purple tinted very thin wool jacket. More like a zippered shirt if that's the type you want. Looks flimsy, very little structure like a shirt and I didn't like the color. The zipper is also very flimsy looking. Ice breaker used to be better quality.
Quantum in Loden
[This review was collected as part of a promotion.] Quantum is always terrific and we couldn’t resist buying another in this colour. It is lovely.
