The first factor to consider when picking a dry suit is how the suit will be used. If you plan to spend weeks in the cold exploring remote destinations in a watercraft, then you will need the best survival dry suit. If, on the other hand, you are kayak fishing the shoulder seasons or canoe camping in northern regions, then a semi-dry suit will be more comfortable. If the chances are high you will enter the water, such as white water kayaking, then a full dry suit is a mandatory equipment. For occasional use on the worst days, you can save some money on a cheap dry suit with the most important features.
