    • Cost a little more than some other brands but worth it.
Size: Large Color: (001) Black / / White
I always buy Under Armour baseball pants for my grandson. Have tried others but Under Armour just fits better and is a nicer quality. Very durable and are worth the price. They are stretchy and he says they are very comfortable. They can handle all the sliding into bases and rolling for balls a kid can dish out. Using the over the knee socks with these shorter pants is perfect. Looks good on the field! ... show more

    • ⭐️⭐️⭐️⭐️⭐️ Durable, comfortable baseball pants — great for practice & games
Size: X-Large Color: (075) Baseball Gray / / Black
⭐️⭐️⭐️⭐️⭐️ Durable, comfortable baseball pants — great for practice & games We bought these Under Armour Boys Utility Baseball Pants for my son’s season, and they’ve held up really well. The fabric feels tough enough for sliding, diving, and repeated use, but it’s still flexible and comfortable — no complaints about tightness or chafing. The fit is true to size, and the elastic waist with belt loops makes them easy to adjust so they stay put during play. After multiple practices and games, the seams still look solid and there’s no noticeable fading or wear. They also wash and dry well without shrinking, which is a big plus for busy parents. My son likes how they look and says they feel “easy to move in,” which is exactly what you want for baseball. Pros: ✔️ Durable material holds up to active play ✔️ Comfortable and flexible ✔️ True-to-size fit ✔️ Washes well without shrinking Cons: ✖️ A couple of colors run lighter than pictured (minor) Overall, these are great baseball pants for youth players. Good value for the quality, and we’ll definitely get them again. ... show more

    • Perfect Small 1/2 Size
Size: Small Color: (100) White / / Black
Review Image by Allison
If you feel like your kid is in between sizes, these are perfect! My son is in between a small and medium in the Champro brand and the small in these fit like a small 1/2. He also loves that the part under the knee isn’t elastic! Super comfortable, thin material for breathability AND the white isn’t see through! Win win! ... show more

    • Great baseball pants.
Size: Medium Color: (075) Baseball Gray / / Black
The sizing on these seems to be different. Had to return some to find the right size. Other than that, the quality is very nice for the price. We have several pairs.

    • Great Fit
Size: X-Small Color: (001) Black / / White
We picked up the Under Armour Boys Utility Baseball Knickers for my son, and they’ve been fantastic! The fit is true to size and the fabric feels both strong and stretchy, which gives him great freedom of movement for running, sliding, and fielding. They’re comfortable enough to wear all day at practice or during games without feeling stiff. The material holds up really well — even after repeated washes, the color and shape stay true. I also love the clean, athletic look they give with his uniform. If you want durable, comfortable baseball knickers that help your young player perform their best, these are a great choice! ... show more

    • Quality item
Size: Medium Color: (075) Baseball Gray / / Black
Purchased this size for my 8 year old son. They’re still a little big in the waist but with the belt it works out. They’re wide around his calve but leaves room for growth. I appreciate the quality of them as well.

    • Worth the buy!
Size: Small Color: (001) Black / / White
My son loves these! Durable and thick and hot him just at the knees where he wants them - not too long and not too short! We've been buying these for a year now and have every color! Great for practice and games. Buy them!
