I bought thermal tops and bottoms from Amazon for a recent school ski trip but it was so hot we didn't use them. I doubt if they will fit our Grandson next year. I suppose he could wear them in his sleeping bag if we manage to get away at Easter.
They are really fleecy and soft. They have an Oxylane brand name. Made in Egypt of all places.
Amazing family weekend with old steam engines, classic car displays, market stalls, and full catering and bar. And camping on site - Save £25 by booking in advance.
