Many people make the mistake of buying thermal protection that is marginal at best and do not enjoy diving as much as they should because they get chilled. Keep
the following observations in mind when choosing a dive suit:

• Stocky people retain body heat much better than slender people do.
• Older people, women and children seem to get chilled faster than average.
• Most people can do one dive and stay comfortable, but, the second or third dive of a day is when heat loss becomes very noticeable.
• Even in the tropics, after a week of heavy vacation diving, many people start getting chilled during the last few days.
• Water temperature in many dive areas can change up to ten degrees or more between winter and summer, so this factor must also be considered when choosing a dive suit.

REMEMBER: Each person should determine what thickness or style will best fit his or her needs based on recommendations from instructors or local dive store professionals. If your suit is too warm, you can flood it to cool off, but, if you begin with insufficient thermal protection all you can do is shiver or stop diving!

75-85 degrees
Titanium Tropical 1mm jumpsuits for warm-blooded divers. 3mm shorties can be worn on top of the polar fleece or 1mm hooded vest worn beneath the Titanium Thermo-Shield¨ jumpsuits for the lower end of this temperature range. Most divers will appreciate full 3mm jumpsuits for deeper diving or extended dive vacations.

65-75 degrees
5/3 mm Kobalt Pro-Flex¨ or Titanium jumpsuits for most divers. 5.0mm two piece Farmer John/Jane and jacket suits for extended or deeper diving. For diving in lower temperatures in this range, consider adding a 3mm shorty beneath the jumpsuit.

50-65 degrees
7/5 mm two piece Farmer John and jacket suit, either Kobalt Pro-Flex¨ or Titanium Toaster¨ models for extended or deeper dives. (Most major scuba training agencies recommend drysuits for diving below these temperatures).

45-55 degrees
7/5 mm two piece Farmer John/Jane and jacket suit, either Kobalt Pro-Flex¨ or Titanium Toaster¨ models for extended or deeper dives. Extremely long or deep diving may require you to “layer your suit” with additional neoprene accessories such as Titanium hooded vests, or shorties.

30-50 degrees
Dry suits only. All dry suits will require proper undergarment and/or layering, especially as the temperature drops towards freezing.
