Women's Snow ski snowboard pants Spyder Echo Gore-Tex (GTX) Women's size 6

Basically new, sister bought new last season, skiied two days (maybe 4-5 hours total, maybe like 4-5 runs total lol), and decided it's not for her. Jacket, pants, helmet pads washed after ski trip and literally sat in a storage box for 7 months (No damage, minor wear along boots and knee dirt, as expected from skiing) https://www.spyder.com/pages/size-chart-womens
