Vibrant colour, good stretch and comfortable fit for the pool or beachI took everyone's suggestions to go up one size and the fit is perfect for my 9 almost 10 year old. The colors are great and no fading has happened yet.I’m a flat chested 5’2” adult. I wear a S in men but they are often too long in the torso. I got the size 16 and it fits like I had it tailored for me. Can’t wait to start wearing it on hikes.I know rash guards are supposed to be tight, but this was WAY tighter than expected for the size. We ordered up in size and when my child put it on it was still tight and so thin you could see nipples through it...Fit is good, my 11 year old is about 54" tall and thin to stocky build. It doesn't dry very quickly is my only complaint but I was looking more for price and coverage, which is satisfied with this product.Colors are great and my boy loves blowing these weed seeds in the springtime.This is the second TSLA rashguard I bought for my son. Last year, he was wearing size 6 clothes. I bought him a long sleeve xsmall (8). Although the sleeves were a little long, the fit was perfect! He wore it for a week straight at the beach with a ton of comfort and no sunburns. This year it still fits, but he needed a new short sleeve one. He's currently wearing a size 8 clothes. I bought him a small (10) in the cobalt blue. Again the fit is great! And I'm pretty sure he will be able to wear it next year too! Great product!It seems like a decent product, but we found it to run a bit small. (I know rash guards should have a tight fit.) My son usually wears a 5/6 so I ordered a size 6, and it was just too tight. He does have pretty broad shoulders for a little guy though, so it may work better on more narrow shoulders. Just to give a better sizing idea, he is 3’11 and 45lbs. Returned to order the next size up.
