[This review was collected as part of a promotion.] After more than a decade in California, I moved back to Michigan in the Fall. I realized that I was no longer acclimated to winter, so I began researching for options to stay warm. I came across Icebreakers and I'm so glad I did. I have two pair of their 100% wool layers and a 100% wool top. At first I was worried these 260s would be too thick to wear under jeans, but they feel fine - and aren't too much thicker than my 200s. If you're on the fence of getting 200s or 260s - go with the 260s!
I bought both the bottom and top base layers in the 260 zoneknit line. I was shocked to see that the bottom third of the top is actually a mesh-like wool knit that is so thin you can see through it. Hardly a product for cold weather. Likewise, the bottoms are much thinner than my smart wool base layer I have bought icebreaker products before and found them to be very high quality. Unfortunately, it has gone really downhill. I am a disappointed customer and I am returning to Smart Wool.
[This review was collected as part of a promotion.] I have used their 260 highwaist thermal leggings as pj bottoms (perfect under eberjey nighshirts) and as a base layer since last year. Black is fine, but I was excited to see this brown, especially since the accents match one of my nightshirts. These leggings fit just like my tried and true, but I do wish there would've been a closeup of the dotted/vented knit at the rear and calves, which is thinner than the rest of the material. I ended up keeping them, since it's hard to find dark leggings that aren't black or blue and it's hard to notice the different fabric unless I focus on it, but I do prefer the feel/warmth of the non-vented fabric. I'm 26/38 and the S fits perfect for my purposes - they're fitted w/o digging at the waist and never get saggy at the knees/butt with wear, even when wearing for sleep. I noticed they don't specify high waist in basically any of their products anymore, hoping high waist isn't discontinued, cause it's really the best cut for leggings!
[This review was collected as part of a promotion.] I like how the leggings remain pretty thin and it's surprising how warm it keeps you, and I can wear them under my pants in winter while still having flexibility. Nice and breathable too!
[This review was collected as part of a promotion.] Warm and not bulky. Perfect for skiing, long winter walks, to layer under my hiking pants. it also cold be warn under my work pants for cold days commute
