This is the first year I am wearing a rash guard and I really like the fit of this one.  It''s not too tight or too lose.  I normally wear a 4 but ordered both a 4 & 6 to compair.  I ended up keeping the 6 because it was just more comfortable especially with a bathing suit top on underneath.  I have not worn this in the pool yet which is why I gave it 4 stars.  I''m looking forward to trying out in the water and not having to cover my entire body with sunscreen.

I wore this shirt for 5 hours while snorkeling off of Belize in February.  No burn, it fit snug and felt good in the water.  I am 5''9", 140 lbs and usually wear a medium pullover shirt/sweater.  I ordered a large and it was a perfect fit.  Nice and long for my long torso.  Washed and dried nicely (low heat).  Tricky to get off when wet, but to save my skin from the harmful rays it was worth it.

So much smaller than you think. The collar is a bit tall too.

It''s a little tight around the neck, but you only notice it when you''re taking it on and off. Sleeves and torso are the perfect length! For the price, I thought the quality was great.

After reading reviews I also ordered a size or two larger. I''m usually a 6 and I got a 10. I didn''t want something super tight around my neck and I like the fit a lot. It''s fitted still for sure and clings to my body in the way elastic suit material is expected to (i.e. this is not a baggy throw over tee at all), but it''s not skin tight. It''s really cute and I love not always have to sunscreen my entire back since I''m in the sun a lot in cali. Great purchase!!

Light weight feel shirt.  Bought it extra large due to concerns of rash guard shirts fitting tight.  I was very pleased with fit and comfort while swimming in our pool.
