Dive Shirt


from Chattanooga, TN, US

I bought this as a gift for my daughter she hasn't tried it out yet. But she loved the style and material. She wanted something that would keep her warmer while diving. She's around 134lbs 5'5" and I ordered an 8. It fit her perfectly.


Whole Family Wears One!


I bought this shirt for myself to wear under my 3mm wetsuit but quickly realized that it was perfect for keeping me warm while snorkeling. I liked it so much that I bought one for my daughter and two granddaughters and we all LOVE the shirt. We stay warm in the water and have doubled our snorkeling time. (I even bought the male version for my husband) I found that "weight" was a better guide for ordering. I am a 36" chest and the size 10 fits me great. The shirts are a little snug getting on and off but that's what keeps you warm!


sizing runs smaller


very tight fit, runs small for listed size. Sleeves too small/tight at the end, probably great for diving, but not for snorkel use.


Have purchased THREE of these!


I bought one of these for myself to wear while snorkeling and as an extra layer under my 3mm wetsuit when diving. It was great for both situations. I was able to extend my snorkeling time because this shirt kept me warm. It also helped keep me warm on our second dive. I liked it so much that I ordered one for each of my granddaughters to wear while snorkeling. I bought a size 10 because it was the best match for my weight. Even though I was a 35 chest, it still fit fine. The shirt is a little tricky to get on but well worth the effort. The inside lining is a little "sticky".

Questions about this item:

Shopper  ???? This sounds perfect for my warmth in the water and sun protection needs while I am in the virgin islands. Are there others to compareI was chatting with KAS but lost connection
CARY B  This Mares top was wonderful. Now the material does feel like wetsuit material so it's thick. It fit under my 5mm wetsuit no problem. Shirt was well made and will help you stay warm. I purchased a separate rash guard, can't remember the name at this time. The rash guard would actually make me freeze when I got out of the water. This Mares shirt worked well. The only other product I would recommend is a product called a shark skin. They are the BEST, but you will have a hard time finding one her in the USA. They are made in Australia and the company doesn't ship from their website anymore. And that top is VERY expensive. You are looking probably at $60-$80. Honestly, for the Virgin Islands. Get the Mares top. It will work fine. Cary
GLEN W  If you are going to be snorkeling and kayaking, etc., it's a good choice. It lets you move, but protects. For diving, I use a dive skin or light wet suit, and gloves. Seems no matter what, I scrape against rocks and coral at some point, and feel better with full body protection. I also use a .5 cap when snorkeling, because my scalp burns easily. I generally am in Hawaii, where the water is not as warm as the Caribbean, so be careful of overheating ... a rash guard is also a good alternative for snorkeling in warm water.
DEREK R  I would mostly compare it to a rashguard. Its able to keep in some warmth in while being really flexible and not bulky feeling. It does however seem to stain easily. It would be nice to have a darker color.
Mary G  Is there a standard sizing chart?
Frank L  We are working on getting the Mares Size chart online. For now, please call our sales team for assistance.
ERWIN M  My best guess is to use the US standard size chart.
Wools L  Looking at size 4 or 6 - but don't see size measurements of sizes?
