O'Neill Men's Thermo-X Short Sleeve Insulating Rashguard Reviews

9/3/2018 Good quality shirt that add some warmth

By Markus

There are some places we go swimming where water and ambient temperature are a bit low. This shirt makes me feel comfy in these environments. The fabric seems to be of good quality and durable - but keep in mind I''m not wearing it too often, just where required. So I cannot really tell but at least it makes a durable impression.
I bought an M size but should have bought L because M is really tight. It should be a snug fit for its purpose but keep in mind the sizes feel a bit small. So if you are torn between two sizes I recommend for you to buy the larger one.

By Jack

Helps with chilly SF East Bay temps, need to wring it out a bit before you can get it off. Otherwise fine.

1/2/2020 I’m happy with it

By LisaR

Nice fit and keeps me warm in the chilly public pool. Exactly what I’d hoped for.

12/24/2019 Warm, but good luck taking it off

By Zoso

I like it, but removing it over your head when wet is extremely difficult. I wish it had a zipper in front.

12/5/2017 Glad I bought these

By Austin

I use them for exercising in an outdoor pool early in the morning. My exercises consist of my uppermost body starting with my shoulders up being out of the water. They work very well for keeping me comfortable in the water especially when there is a breeze blowing.

Their sizing chart is true to size.

12/4/2019 Wearing a Sponge

By Unhappy Swimmer

I thought this rashguard would help keep me warm when swimming in chilly water. Boy was I wrong! The shirt feels like it is made out of fleece, which I thought was very odd. Shouldn’t it be water repellent? Well, there is nothing water repellent about this shirt. It is a giant sponge. It soaks up water, weighs the swimmer down, and makes chilly water feel ice cold. I don’t get it. I feel like a dummy for wasting so much money on this product.

It fits and keep me warm as I bought it for.

1/22/2018 Product is as advertized

By Philip

I was looking for a little more insulation. I was trying to replace my instotherm body glove. The thermo x fits and wears well,but holds a lot of water when you get out of the pool.
