Last snowboarding season I got a Duofold Women's zip neck base layer which I absolutely love (http://www.amazon.com/gp/product/B003YMMBVW/ref=wms_ohs_product?ie=UTF8&psc=1) so I thought I would try these thermal bottoms after reading the reviews saying they were perhaps more suitable for women. I bought a size small instead of my normal women's medium and these fit perfectly. I hit the slopes today and they are silky smooth and very comfortable. I like the flat waistband. I wish they were heavier. I would rate them as more lightweight than medium weight. If they didn't feel so darned nice I probably would have returned them.
