[This review was collected as part of a promotion.] My boys are 6 and 7 and these fit them perfectly. They are both around 50 pounds, give or take a few. These boxers fit them great around the waist and legs. They are breathable and comfortable to wear throughout the day. We will be buying more very soon!

[This review was collected as part of a promotion.] These are great for my boys. This is the first time that ever used Reebok brand. They're affordable and have great prints that are fun for kids. Although I would prefer something with more natural material, this is great moisture wicking and boys that are on the run. They are great quality, comfortable and well made.

[This review was collected as part of a promotion.] The medium size fits my 7 yrs old son perfectly. They provided a comfortable fit without been to tight and he can move around easily throughout the day. The material feels soft, breathable and Great for active kids.

[This review was collected as part of a promotion.] My son said these underwear are very comfortable with a soft material that doesn't itch or rub. He says he can move around freely and they give good support to his private areas. He said the simple designs and solid colors are great- not too childish (he's 12). He said he would recommend them.

[This review was collected as part of a promotion.] I don't know if they are as effective as they should, their fit is good although the size to be L is a little small, and it is not elastic enough if you are size L, it feels good it is comfortable, and for its value it is fine, only if you are size L better buy an XL.

[This review was collected as part of a promotion.] I received this product, complementary in exchange for my honest review. He found these to be a very good fit, and the sizing on the back is accurate. A nice waistband that didn't roll would highly recommend.

[This review was collected as part of a promotion.] These underwear are sturdy even though they're so thin. My son likes that there's no itchy tag and that they're thin and light. The fabric is comfortable and a good quantity come in the pack. The only downside is that they run VERY small!

[This review was collected as part of a promotion.] He loved the feel of his Reebok Performance Boxer Briefs. He said they moved with him while playing. He said the fabric was light weight and moved with him. Said one of the best pairs of underwear he has worn.

[This review was collected as part of a promotion.] Soft and thin fabric with a bit of stretch in the legs, enough to be comfortable but not too much that they slide around or bunch up. The waistband is fantastic, extra soft and cottony inside the elastic to keep from itching or anything. These seem like they will hold up well after many washes and don't require special care. I size up because my son doesn't like them too tight and they are a perfect fit.

[This review was collected as part of a promotion.] My grandson loves these boxer briefs. They stretch nicely and they come down on his legs enough that he dose t get chafed. The colors were nice and bright too. When washed they washed nicely and didn't bunch up or shrink.
