One-piece Crochet Pattern (written in English, US terminology, abbreviated, 1 PDF file) for a trendy winter sports headwear - Balaclava Ski Mask.
This model has an extended, V-shaped, downward-expanding neck warmer that gives extra protection from wind and cold.
A contoured ergonomic design and unique 4-way-stretch ribbed texture allow the finished product to fit any Kid, Teen or Adult head (sizing is a matter of GAUGE).
Being mostly unisex, the proportions of this balaclava model are the best fit for women.
The main part of the item is made with double crochets.

NOTE: Here is a similar ski mask designed for a larger, fuller men’s face (the main part of the men’s model is made with HALF double crochets):
