    My second Arena tech suit! This brand fits my body shape,  so an on sale price was a no brainer. As we self quarantine,  this will be stored for a while, no pools open!

    5 Review Stars By abarrow

    The Arena Carbon Air is a wonderful suit. I usually wear between 28-30 for a practice suit. I'm 5'6, 125-130 pounds. I tried on a size 26 first and got it on within 3 minuets. It was a little fast so I tried on a size 24. It fit perfectly. Putting on a tech suit should take 8-10 minuets, these suits should be REALLY tight. I didn't find it that hard to put on, you just have to inch it up your body. It was very comfortable, especially the shoulders. Plus it felt like it was made of very high quality material and did not feel like it was going to rip (best feeling ever when putting on a tech suit). I had full range of motion (I swim the IM, range of motion is a key factor in choosing this suit) and look forward to wearing it in the pool. In all I think this is a wonderful suit.

  • 1/20/2016 Haven't worn it in the water yet but daughter loves it so far

    4 Review Stars By Bellis

    We usually wear the Speedo LZR Elite, but since they tend to stretch out fairly quickly decided to try something different this time.  Daughter is 15, 5'6" and normally wears a 28 in a practice suit.   We ordered a 26 and it seems to be the right size.  It took her about 10 minutes to put it on - we don't want the suit so tight that it takes 30 mins to put it on as I think that adds un-needed stress.  She hasn't worn it in a meet yet but will next week but she loves how it fits out of the water.  Will try to post an update after she swims in it.

    This tech suit is really good! The fit is really nice. I wear a 30/28 for practice and i got this in a 26.(I'm around 5'5 and 105 pounds)it took me about 10 to 15 minutes to put on and in my opinion that's really little time compared to the carbon pro which took 30 minutes to an hour!!!! Overall, its a very good suit and comfortable on the shoulders as well. Definitely worth it!

    5 Review Stars By Masters swimmer

    For a mid price tech suit, this really performs and is a wonderful option.  I originally ordered a 24, based on the size chart on the swimoutlet site.  However I had to exchange it for a 26.  I went on to the Arena website and according to the chart they had I am a 26, (so this suit is true to size based on that chart). I recommend people check the size charts posted on the website of the suit manufacturer.  In the end, I swam fast - dropped 1 second on my 50 free and 100 free and am officially in Masters top 10 in the US for my age group.  So I am happy.

  • 5/8/2017 Great suit, with a great fit!

    4 Review Stars By PNS Swim Mom

    My daughter is 14, 5'5", 106 lbs, slender with a long torso.  Most of the girls on her team with tech suits typically buy Speedo brand, specifically the LZR.  When she was professionally fitted for a suit, her measurements fell between 2-3 sizes, depending on the suit.  We picked the smaller size, since she is slender.  However, even with going with the small size, the Speedo suits allow too much room in the chest, which causes water to enter the suit at the top. Someone on the team suggested we try a smaller "longer torso" suit, but Speedo doesn't offer long torso in smaller sizes than 25.  After paying attention to different brands at meets and reading many of the reviews for different brands, we decided to give Arena tech suits a try.  My daughter is very happy with her size 26 Arena Carbon Air suit.  It fits perfectly everywhere, including the chest. It's not too difficult to get on (with my help), and comfortable enough to wear for hours at a time.

    5 Review Stars By Jen11871

    Arenas seem to fit my daughter best and has been wearing the ST for awhile. Size 24. She is 5'2 and about 118-120lbs. Broad shoulders. We decided to try the new carbon air, we were told she'd need to size up..not true.. 26 too big..recieved the 24 and it fits like a glove. Beautiful suit, expensive but, it could be worse. Looking to purchase the second suit now..a very good buy!,
