A first time for everything!

After years of thinking about it we have taken the plunge and booked a week in Filzmoos first week of Feb.
Have no idea what to expect - absolutely no experience - and now fairly confused about what we should be taking in the way of clothes- Been to nearly every TK Max in SE England in last few weeks and basically bought thermals Fleeces and jackets . Some are telling us we will be too cold some we will be too hot - Dont take cotton or cotton is ok if not used as base layer.
Have booked absolute beginner classes for myself my wife and 2 daughters (in their twenties).
I'm sure all will become clearer when we arrive but any advice would be most welcome

We just took a friend with us for the first time, and kitted him out similarly to yourselves. You can never depict what the weather will do! We have just come back from La Plagne where it was -24 with wind chill, yet last year we were sunbathing in 16 degree warmth!!. As long as you have a thermal base layer, and fleeces to bulk up with, you will be covered for body warmth, particularly if you have windproof jackets. The most important thing is to have really good gloves, socks and a hat, as this is where you may get cold if temps are low. Get these basics right and the layers can come on and off as you please!!Personally, cotton is not a favourite as it retains moisture but I am sure others will ski regularly in it. Have Fun!!
