I’m 5’ 10”, 160lbs, 40” chest and I bought an XL. the quality is excellent. It is thicker than expected which is good. The fit is perfect. Not to tight and not to loose. This will be perfect for those cool fall days on the water. I’m more than pleased with this. Would definitely buy this again.

Hi Patrick, thanks for sharing such a detailed review! We’re thrilled the fit and quality exceeded your expectations and that the rash guard will keep you warm on those cooler days out on the water. Delighted to have you as part of the Platinum Sun community!
Superb quality - soft and fitting, warm in winter. Neckline a little too tight which makes it harder to take off when wet after a swim.
It’s winter here on maui which means we did into the 60s before sunrise when I’m in the water so this is perfect for keeping me from feeling the “chill”
The sizing is great.

Dear David, Thank you for your feedback. Stay warm :)
I wore this more than any other rashie when I was kiting on Aruba... and it literally saved my skin!! There's a reef break and if I ever took a spill it was more than just rash protection. The best part is that it was just the right thickness to feel warm & protected without over-heating. P.S i hope PS can make pants like this someday.

Hey Harly, the rashguard looks great on you !
See you on the water !
Rashguard for kayaking
I make sure that I am protected from the sun when going out kayaking. I bought this rashguard expecting just a regular rashguard, but it exceeded all my expectations. The quality is of highest standards and the fit is spot on. It is also eco-thermal that it will keep you warm on cold weathers. Rashguards have never been this valuable. Thank you Platinum Sun for this!

Absolutely the best
This fleece rashguard is 100% the best! It looks great, fits great, and it keeps you warm on cold weather. The black color really makes you look really good as well. This is by far the best rashguard I've seen since forever.
Store owner replied:
Happy you like it !
This is the best pick for SouthFlorida winters :)
Enjoy !
I’m 5’11”, 150 lbs. Based on platform measurements, I’m a medium size (due to my arm length, small would likely be to short in the sleeves). Item is too loose around neck. Since it’d be used for scuba diving, having water freely flowing through neck, it wouldn’t work for my application.
To be honest, I have not used it yet. I am signed up for a long open water swim event in California this summer and bought it for the event. I was hoping to give it a try or two beforehand.
I probably shouldn't use it in the pool????(I could use help here.) I want to see if it will work for my older brother, who has COPD, but can swim without his oxygen. He finds the pools too cold at this point, so wanted to check if this would work for him.
The fit (XL) is perfect for me ..6'2", 180., with long arms.

Greg, iove hearing the fleece-lined Thermo Rash Guard fits just right and actually keeps you warm when the water’s cold. That snug fit plus cozy lining is exactly what we built it for, hope it earns a permanent spot in your cold-water kit.
Store owner replied:
Thank you so much, Judy! We’re really happy to hear the fleece-lined thermo rash guard fits you so well. Wishing you lots of warm, comfortable sessions out on the water.
The thermal rash guard works well. I am 5' 9" 170 lbs and it is an XL.
Store owner replied:
Thanks for the review, David. We’re happy to hear the thermal rash guard works well, and we appreciate you sharing your height, weight, and size choice.
Purchased multiple items for under my drysuit & undergarment for scuba diving in the PNW. Nice and warm!
Store owner replied:
Hi Christine, thank you for the kind words about the quality and material! We’re excited for you to try it out once the cooler months roll in and enjoy warm, comfortable swims.
I purchased this for cooler weather and it works great. Falls in between a rash guard and a wetsuit - just what I needed.
Shipping was fast and the team was very helpful (when I rushed and ordered the wrong size!). Thanks!!
Nice and warm, using for swim spa workout in Michigan winter with temperatures in the 20’s and has kept me warm! Wish it was just a little more roomy but that is t surprising given a 3x is my usual
5 days a week I participate in an outdoor aqua aerobics class from 8-9 am. Here in Northern California it had been getting chilly wearing only a regular swim shirt over my bathing suit. So far this thermal shirt is making a big difference not having cold shoulders. Since it needs to be a tight fit, I pull the shirt DOWN first and THEN pull my bathing suit over it. The shirt does not ride up during my class and keeps the above pool part of me warmer.
Size Medium- Female 140lbs 38DD 5'7. Love this thermal i not only wear it in the water on cooler days, I wear it hiking and backpacking. Full range of movement nothing rises up or binds. Soft on the skin and well made. It not only looks great on, its great for all kinds of outdoor (land and water activities). On coldest Colorado winter days, I wear a shell or even a vest over top and it keeps me perfectly toasty. Thanks Platinum Sun for ANOTHER Eco Friendly perfectly made product!!
I'm 6'2" and weigh 225 lb at 80 years of age. I have long arms (36" sleeve) and carry more weight than I would like. The Platinum Sun swim shirt (size XXL) fits me well. I especially appreciate the free arm movement as I am swimming. In addition, I've noticed that there is very little drag, if any, with this swim shirt. And, lest I forget, yes the fleece does a nice job of keeping me warm. I swim outside year round in an 80 degree pool with outside temperatures last winter getting down to 40 degrees.
Good fit, awesome
This is one of the best rash guard shirts I've ever owned. The shirt is literally perfect for any activity you can think of. It kept me warm despite the cold weather, and it felt very comfortable when worn. The shirt is also very durable; it did not tear or fray even with all the wear and tear I put it through using it for mountain biking, hiking, kayaking, working out, etc.
So soft and warm
My boyfriend got me this rash guard, and I love it! It is super flattering, and I like that it is black. It's soft, comfy, and warm. The material is very stretchy, and the fit is perfect. I. And it is way more comfortable than the other ones that I have tried.
Very warm and flattering
I love this fleece; it is perfect for all outdoor activities, especially winter sports. I haven't experienced any kind of chafing or discomfort with this fleece. The material is very soft and warm. The zippers are high quality and easy to use. There is enough room to wear additional layers underneath without being too bulky or feeling restricted.
Worth my money
My husband and I both bought the rash guard for diving in the ocean. We live in Hawaii, and it gets pretty cold (especially this winter), so we wanted to stay warm while diving. I've used the rash guard several times. The fleece rash guard helps keep you warm when in the water, which I really appreciate. It's great for diving in cooler weather too.
Great rashguard
This is a seriously high-quality, long-sleeved rash guard. The sizing information was spot on, and the length fitted me really well. The color is lovely and bright, and I can imagine it's going to be great in the pool! It has a fleecy lining, so it's really cozy and warm! I'm so pleased with this purchase.
