Is Wetsuit necessary?
« on: 17 Mar 16, 15:05 »
Other than water temp that's 22degree and below, I've always preferred to dive in rash guard( both top and bottom) than wetsuit.

Does it affect anything other than buoyancy?

I've learned to control my bouyancy while diving with my rash guard too. And I do have thermal rash guard for night dives.

What's your thought about it?

If you're good and saving on travel weight, can skip on wetsuit(s)
The dive centre always have appropriate thickness for their location

But they usually only provide shorties in warm waters and if you tend to brush across things, you might wanna get the long sleeves to protect yourself.

As far as I'm aware... the purpose of wearing wetsuit is for one to keep warm, as our body lose heat faster underwater... if a person can tahan cold water... don't see why not you can't dive in the nude if you want too... I'm not recommending it btw... jellyfish and sensitive body parts and such... I've even dive in Lembeh wearing a 0.5mm wetsuit over my rash guard... mostly for protection against stinging creatures.

But of course, being 'naturally insulted'... aka, Fat... keeps me warm most of the time....

To me it is. Many other older instructors feel the same way as well. It's not just for thermal protection. It is also for protection against stinging marine creatures.

I started out diving in a shortie wetsuit. Till one trip when it was season end and there was a jellyfish bloom. Thousands and no avoiding them. That was the last time i wore a shortie. Full wetsuit from then on. Now with a hood as well. The itch from stings is not worth it IMO.

it's like underwear.. some people say it's a must, some prefer to go without!

just a matter of preference. no right or wrong.

to me when diving in warm water, wearing long pants and long sleeve either wetsuit or rash guard is fine, most important is to protect against stinging stuffs from the sea and protect your skin from cuts, our skin become very soft after socking too long in water, any light brushes with hard object can cut the skin.

Now a day, I usually wear shorts with long sleeve rash guard while diving, this also remind me to be more careful not to damage corals as well as my skin.

Well, in addition to comfort and exposure protection, diving without thermal protection makes you feel tired quickly, technically.

As water conducts heat away from the body at a higher rate, the body also needs to work harder to maintain its core temperature and, in turn, uses more energy. Not forgetting, if you're on the surface in wet clothes, evaporation is going to keep the skin cool as well.

Now, four 60-minute dives in 28░C (~9░C cooler than the healthy human core) water and with the subsequent surface intervals in the sea breeze - that's going to be a whole lot of energy used up! Tiring man!

Having thermal protection allows the body to reduce the energy needed to maintain core temperature by keeping heat in. Also, IMHO, when you change out of the suit into dry clothes during the surface interval, it's also considerably more comfortable. Of course, some people do argue that squeezing into a wetsuit is more tiring than anything else... :P

Good point! next time I wear full 3mm wetsuit and hope will be less tire after the dive.

I highly doubt wearing wetsuit will help in protecting you from stinging creatures in the sea. If you are to get stung, you will get stung. One of the instructors likes to wrap himself up, wearing 2 wetsuits, hood and gloves even at Tioman.
He was still stung. at the one part that was left uncovered; between the nose and the mouth at Tioman.

Thou I have only dived 4 weekends at Tioman, I wear only a thermal vest and shorts, at most a long sleeved rash guard, no bites/stings. *shrugs*
