REI Heavyweight Tights
Here's what other sites are saying:
Our warmest REI-brand base layer, the women's REI Heavyweight long underwear tights are perfect for hiking, skiing, snowshoeing mountaineering or cross-country skiing. Heavyweight polyester/spandex fabric wicks moisture and dries rapidly. Soft fabric offers 4-way stretch for ease of movement; elastic waistband fits and moves comfortably. Fabric provides UPF 50+ sun protection. The women's REI Heavyweight long underwear tights feature nonchafing flat seams and a smooth outer surface which makes them easy to layer under other clothing.
