Questions and Answers for Bare 7mm Elastek Super-Stretch Coldwater Diving Hood:
what is the best way for figuring out what size hood i need?

Unfortunately, height and weight are the main measurements, but typically the hood is the same size as the wetsuit. As long as the item is not used in the water you have up to 60 days to refund or exchange it.
