Boys' Superhero tee from Red 21
With the official start of summer only two weeks away and the warm weather already here in my neck of the woods, I’ve been sifting through my son’s clothes from last season and realizing that ack, he needs a whole lot for this year’s summer wardrobe. Darn kids, why do they grow so quickly?

One of my first stops on the web for boys’ clothes has always been Red 21 Boys, whose stylish, sturdy duds have withstood more than a season’s worth of beating up from my active son. They’ve always got a great sale section, not to mention, amazing customer service. (Hey! A real person on the phone!) Not surprisingly, our readers with boys are huge fans too, so I’m so thrilled to welcome them back as a sponsor (whoo!) and share with you some of my own favorite picks from their fantastic summer collection.

With Avengers characters on every piece of boys’ clothing
everywhere I look, I’m digging this cool Superhero crewneck

Boys' swimwear from Red 21

The Camo Peace swim trunks are a cool twist on the classic pattern for boys. My son loves the comfortable waist and I love the drawstring; no more reminding him to pull up his bathing suit all day long. Pair it with this solid orange rash guard and you can keep track of him on the beach, and keep him a little more protected as he plays in the sun.

Boys' astronaut rocker tee from Red 21

As if astronauts could get any cooler, now they rock out in this Astronaut Ringer tee, made from super soft pre-shrunk cotton.

Boys' treasure map swim trunks from Red 21

Such a fun twist on the pirate motif with these Pirate Treasure Map swim trunks. I’m a fan of the cut of these and really, all of their swimsuits, which are especially suited to my skinny little boy.

Boys' pirate ringer t-shirt from Red 21

If you’re digging the pirate theme, I also love this Ahoy Matey ringer complete with this year’s popular mustache motif. I know that would get a ton of use around here.

Boys' shorts from Red 21

Tie dye just seems a whole lot cooler when it’s covered in cool submarines and underwater creatures.  –Kristen
