This is a Montbell Chamois Pullover. The style may still be available, but this is an old Montbell piece, and this color may be discontinued. It's in excellent condition, having only been tried on and then stored. The size is XL, with approximate measurements of 58cm width and 68cm length. It's thin but warm and of excellent quality. The color is a vibrant orange, making it easy to match with other items.
