Fit well and comfortable
Yes , I recommend this product
Bought them in small for me, I'm 5' 4"130 lbs and xs for my daughter 5'6" 115 lbs., for a scout wknd w/temps 30° and windy in northern nj. They were fantastic. Very comfortable, however a bit long for me. So I tried the Patagonia mid weight, but they were short in the rise. I might have the rei bottoms shortened.

Great Basic Base Layer
Yes , I recommend this product
Bought 2 pairs of these leggings for Kilimanjaro and they kept me warm through all those chilly nights in the tent. They do run a bit big but I layered them over compression tights for an extra layer of warmth and they were very comfortable. Only complaint is the waistband elastic quality is pretty cheap and after a couple of days of wear it had permanently creased. Otherwise, great buy for the price!

poorly constructed waist band
No, I do not recommend this product
these were warm and comfortable which makes me disappointed that the first time I washed them - cold air dry - the waist band folded and bunched up making it lumpy and less comfortable. I have returned them

Effective but waist band issues
Yes , I recommend this product
These midweight base layer tights are awesome in every way (keeps you warm & high-rise keeps the snow out) except for the fact that the waistband doesn't stay flat. It bunches up & the elastic doesn't bounce back into a flat strip, more like crinkled up. Otherwise, I'm happy with them, and they do the job I want them to do.

warm and comfy but flawed
No, I do not recommend this product
Tight s fit well, have a nice texture and weight. Major flaw is the tag in the back. since these are tights and fit snug, the extra stiching in the back for the tag is very uncomfortable and scratchy against skin. As soon as I find my seam ripper I am going to take the tag off and hopefully that will render tights wearable.

Great Thermals
We got these for my wife before we went skiing last week. She was only wearing lightweight rain paints over these and stayed plenty warm on the mountain. Great thermals for the price.
