Hi. I need to buy some cold weather wear for snow (not actually skiing). How does ski wear come up - say salopettes or all in ones/anoraks. Which would you recommend as the best type of these to buy an all in one or seperates?. Is it roomy or tight fitting - I have a biggish nearly 2 year od and a 3.5 year old girl and wondered what sizing I should be looking at or does it vary from range to range. And if anyone has some they want to pass on please let me know as intersted in buying possibly. Thanks
