Does this shirt keep you cooler. I do jiujitsu and want to wear it under my gi. Suppose to keep you 10 degrees cooler

I do Karate here so its the same... keep it short - NO. It won't keep you cool. Sorry to say, it feels good on your skin, it won't feel so good under such a heavy garment... Plus, it will ruin this shirt... Live with your sweat, make peace with it, love it :) No need for anything under your gi. If you do want something, get a sleeveless top, but this this, its not as tight as one expected. Its good for jogging out showing off your body. If you want to keep 10 degrees cooler take some ice cubes. or spray yourself with that ice cold spray for injuries. If you want to wick sweat better, look for outdoor/hiking tops, they tend to wick much better than UA. I also tried Columbia's COOL ZERO or whatever its called, wasn't tight enough. Go to the shop before you order online, you will get the feeling yourself... Hope it helps. Again, this is one awesome shirt to wear without anything above it. I forgot to mention - AVOID COTTON! Unless you want to be weight down by all your sweat which might make you feel a bit cooler - since you're wet.

Hi there Talise, I found the quality of the gi excellent, but they actually run a bit bigger. I ordered a "4" and it feels like a "5"..hope that helps and enjoy your training:)

Hi and yes - I wear this while running and am very comfortable when doing so. Colder than 45 degrees, I wear this over a dri fit long sleeve shirt over a tee shirt. A few miles into the run, I may have to unzip a bit (when weather closer to 45) and if it warms up, I've taken off and tied around my waist to complete my run - it's very light and lends itself to this well. It's been a great buy for me.

Yes, you could. It isn't as hot as I thought it would be. It is tighter than most t-shirts and I had get used to wearing it. You may have to wear it for a few short periods before trying to wear it all day.

My son loves his, and has been wearing it as an outer layer over other shirts (tees and turtle necks) this whole fall. I would think biggest issue might be getting too warm once you were indoors. That, and getting a size with some extra room for the layering.

This one is very thing and its not to bad, but I still use a slightly larger tee-shirt I use it during my work out at the gym and don't really care if people see it. I do think it can be concealed if one desired

No, you just wear a swimsuit under your wetsuit. This shirt is just for extra protection and coverage. I bought it to wear over a bikini for long days at the beach. I suppose you could wear it under a wetsuit, but it would not be effective to keep you warmer.

I would say that yes, if you are of a medium build, you could wear it discreetly under a shirt. Amazon has a very liberal return policy, so you can easily return it if it doesn't work out for you.

It won't sweat through your clothes, it is bulky, so I wouldn't wear it with a fitted shirt. A loose fitted shirt would be fine.

i'm 5'10, 185-190 lbs and wear this in a large. i would say it runs true to size but also it is longer than your average shirt (like hanes or FOTL). it's good if you wear it as an undershirt, as it won't untuck nearly as easily as those other brands. it's a higher quality shirt, too, imo. the only other shirt i like as much is the hanes beefy T but those are a little more expensive.

If clothing is tight then mybe but think you will be alright . It will make you sweat though if have on for hours or lots of movement.

I like this cover, I haven't felt warmer than average with this one, if anything you might feel a bit cooler at first. I suggest that you sleep with a T-Shirt, I noticed that I stopped sweating while wearing one; perhaps because I don't get under the blanket as much.

It will depend on how you like your gi to fit. I personally like mine a bit looser and I know others that like it snug. I personally haven't dryed mine for the fact of it shrinking as others say they shrink quite a bit. So I would either not dry it or buy an extra size bigger than you think...hope that helps!! Good luck

This shirt is a rash guard. It is very thin, not neoprene, with no insulation factors whatsoever. I use to to protect from sun and to keep BCD from rubbing. I am a Master Diver and have logged many dives with this. It would be appropriate for warm tropical diving to protect from chafing, but will not keep you warm.

I am in bjj and have wrestled all my life. I am 40. The differnce with and withoutPads are huge on the mat. I have not wore pads under my gi so I can't speak to if they will hang on the cotton or not. I would guess they will be fine under gi. I know without the gi my shots are twice as fast with the pads and my knees are very happy. They are not as bulky as they look in the picture. I have 3 of my wrestlers wearing these and they love them. Measure your knee and get the right size. If you are borderline go for the smaller size. I think they have an extra small. If they are too big they will slide around. That is useless to you. Good luck and happy knees. I am in bjj and have wrestled all my life. I am 40.

I don't think it'll be a good knee warmer. Its relatively thin (perhaps to keep cool while you work out). Has the thickness of a beret, or two fleece jackets layered over each other. Very polyester-y in feel as well, so I don't think that traps heat well.

This is a BJJ gi. The sleeves are BJJ cut. The pants are similar to my other BJJ gis, Fuji for example.
