Boys Sun-Ready Rash Guard is rated 4.7 out of 5 by 46.
Rated 5 out of 5 by from A must for summer I love putting my son in a long sleeve rash guard. It makes it so easy cause there is less sunscreen needed. Also warm for the indoor pool. I love being able to buy these year round. I also love the solid colors, they go with many bottoms.

Rated 5 out of 5 by from Excellent sun protection I have been buying these swim shirts for my six grandchildren for 10 years. The sun protection is excellent. There is no need to apply sun screen under the shirts. They are very comfortable because the fabric is so soft. I highly recommend these shirts. They wash beautifully and you just hang to dry.

Rated 4 out of 5 by from Perfect Fit! I was worried that this would stretch out when wet but it fits great! I was also worried my son would get too hot while wearing it but he won't take it off. He's only worn it a couple of times but so far, there hasn't been any fading or damage around the neck or wrists from the sunscreen. We love this shirt!

Rated 5 out of 5 by from Excellent sun protection I got this for my very fair skinned 5 year old. We live at a high altitude, and this is perfect for protecting him from sunburn without constantly slathering him with lotion. I got the white color to help him stay cool, and I sized up to make sure it was a bit roomy.

Rated 5 out of 5 by from Great rash guard This is a great quality rash guard (we haven't used much, but seems well made). I would say this runs on the small side for Hanna, my son is sort of between 100-110 right now, but he is swimming in most of the 110s. But this fits him perfectly in 110 - room to grow, but not huge.

Rated 4 out of 5 by from Great for extended sun play My only quibble with these is how difficult it can be to get beach sand out. But otherwise love these and really love how well they protect my kids' skin from sunburn.

Rated 5 out of 5 by from Best Rash Guard Ever I have been buying these rash guards for 3 kids (ages 9, 7 and 5) for close to 4 years now. I have purchased 10+ of them through the years and am very happy how they mix and match so well with the swimsuits, have long sleeves and a high neckline. The color stays vibrant, never fades even with so much sun exposure. We swim 7-8 months out of the year in AZ and these are a staple for sun protection. My kids ask for their shirts even when we swim in the evening with no sun. It's just part of their suits. I WILL say that in June, 2015, for some reason, 4 of the rash guards I purchased Jan, 2014 and in 2013 started to loose elasticity and the material was thinning. I washed them inside out according to the tag instructions, let them air dry and never put them in the dryer. I called HA, they found the purchases and sent me replacements (or a refund if I wanted one), no questions asked and just requested I return the damaged ones using a supplied return label and my next HA box if I didn't currently have a box to ship in. I was very impressed with the service I received even when my rash guards were purchased so long ago, one was over 2 years old. They really do stand behind their unconditional guarantee.
