Being a size L, I ordered a size L. It is very tight, which makes it perfect for water exercises.

looks good feels good great price but didn''t like to pay 33% for shipping

Form fitting. If you want something loose buy something else.

This rashguard shirt is well made,comfortable,feels good to wear.
I have found in the past with another like product,you should oredr a size bigger.
I normally wear a large tee shirt...I ordered an xl which fit perfect and wasnot too tight.
Many items like this one and wet suits for some reason are made smaller than the normal size.
I will be wearing this item surfing,this spring.Good transaction.

Bought this to wear in Maui while out snorkeling in December to prevent my white body from burning.  Fits snug but good for swimming in.  I generally wear a large t-shirt and bought this in a large and it fits me like an Under Armour compression shirt.
