Here is a neck-seal jacket with bermudas both in size Large (Chuck normally wears a 2X shirt and 38 inch waist pants). I tested the combo in the backyard swimming pool on November 13, 2019 and from the knees down it was pretty chilly, but I stayed dry from there on up (except for exposed head and hands). This picture taken moments after exiting the unheated swimming pool in Phoenix, Arizona, USA. Chuck is 5'10" and weighs 225 pounds (dripping wet) for reference.
