scubaseven 1 Posted April 18, 2009 Wondering if you wore a 3mm shorty under a 7mm wetsuit would that give you a lot of extra warmth or would the two somehow cancel each other out? cheers Share this post Link to post Share on other sites
ce4jesus 1 Posted April 18, 2009 Your biggest worry is mobility and cutting off circulation by combining them. The added mil factor would keep you warmer if fitted properly. Most folks I know where a shorty over a 7 mil for added warmth. Share this post Link to post Share on other sites
jcclink 8 Posted April 18, 2009 (edited) It would definitely help with warmth. I frequently wear a 3mm shorty under a 3 or 5mm surf suit. Which is on the outside makes no difference. Edited April 18, 2009 by jcclink Share this post Link to post Share on other sites
rtrski 20 Posted April 18, 2009 I've done a 3/2 full under a 2/2 shorty, and I 'survived' a dive in 70 degree water. But I didn't enjoy it. The same conditions in a 5/4 wetsuit were much more comfortable. It will give you some benefit, but as others have said the fit can be constricting. Share this post Link to post Share on other sites
davephdv 0 Posted April 18, 2009 Layering is always best in cold weather gear. After drysuits of course. I typically bring a suit of what I believe will be the appropriate thickness for the conditions I expect to encounter. I then bring a vest or shorty designed to use with that suit in case the suit is not warm enough. Share this post Link to post Share on other sites
scubaseven 1 Posted April 18, 2009 Cheers all Have not tried the 2 on at the same time yet, but will to see about the comfort factor I tend to get a bit cold. But I do have thicker boots, hood and gloves now too. But the movement with a camera is probable going to be the main issue. thank you. Share this post Link to post Share on other sites

scubaseven 1 Posted April 23, 2009 for sure keep you warmer. couldnt move well though I tried the two on topside and it was not too bad The 3mm seems very thin, or maybe just compared to the 7mm So will try this weekend in Cape Town and see how it goes Cheers Share this post Link to post Share on other sites
jcclink 8 Posted April 23, 2009 (edited) Today's super stretch neoprene material (vs basic old fashioned neoprene) provides a more comfortable suit, but will permanently compress over time. It's not as warm when this happens. I start the year with a new 5mm surf suit & end up with a 3mm due to compression. This requires also wearing a shorty or vest to maintain a comfortable body temp. I've never noticed that extra layers limit my mobility, maybe in part because all these layers keep getting thinner & thinner.

scubaseven 1 Posted April 24, 2009 jcclink cheers going out tomorrow so will let you know what I think Share this post Link to post Share on other sites
Searcaigh 0 Posted May 15, 2009 Why not invest in a 5mm semi-dry plus a hood. Hood can make a great difference to the comfort level as a lot of heat is lost via the head Share this post Link to post Share on other sites
diverdon 1 Posted May 15, 2009 I like a hooded vest, Henderson Hyper Stretch is the best I have found so far. Share this post Link to post Share on other sites
Timmoranuk 10 Posted May 15, 2009 Rather than wearing a shorty over a steamer, a base layer is better. Choose either a Henderson Polyolefin diveskin or better is an OThree 2mm Deepskin. Share this post Link to post Share on other sites
John Bantin 101 Posted June 1, 2009 Of course it works - if it's comfortable. Layering has been used by man for thousands (nay, millions) of years. If you look at any semi-dry combo, nearly all give a manufacturer's option to layer. http://www.divernet.com/Diving_Gear/243021...dry_or_dry.html Share this post Link to post Share on other sites
davichin 18 Posted June 1, 2009 I would think that if you are able to wear a 3mm shorty under a 7mm and not feel very uncomfortable then, the problem, is that your 7mm is not your size so go ahead and try it with the shorty. Share this post Link to post Share on other sites
jamkos 0 Posted June 29, 2009 And if it's still cold you may always add 1mm neoprene 't-shirt' - it slows down the water circulation close to the body adding some thermal comfort and do not limit the flexibility under water! M Share this post Link to post Share on other sites
Timmoranuk 10 Posted June 29, 2009 My 11 year old son wears one of those tee shirts; a 0.5mm open cell OThree Tech Vest under his 2mm open cell Short John which he tops with a 4/5 mm hybrid semi dry complete with a hydrolock baffle. He gets out after an hour almost completely dry... Share this post Link to post Share on other sites
tdpriest 115 Posted June 30, 2009 All true, but if 7mm isn't enough it sounds to me like dry-suit diving! Tim Share this post Link to post Share on other sites
scubaseven 1 Posted July 14, 2009 thanks peoples some good tips the water in false bay late april was just 10* so I think 2 suits helped, plus hood etc. found the socks made a difference also. dived for 2 months in 15* water and it was bearable for about 50 minutes (pity we had to do two 90mins dives) the water in oz is 12* min in a freshwater lake, but mostly 16* so was not ready for 10* dived there two days ago and it was back to 14* even the drysuit guys were cold though. cheers all 7 Share this post Link to post Share on other sites
