Care Instructions:

  • Machine wash cold (max 30°C) on a gentle cycle to preserve the softness and breathability of the 30’s slub, 30’s cotton rib, and soft wash fabric.

  • Use mild liquid detergent to maintain the fabric’s comfort and protect the black color.

  • Do not bleach or use fabric softener to preserve the texture and natural feel of the slub and rib fabrics.

  • Do not soak for extended periods to prevent any potential fading and maintain fabric strength.

  • Turn inside out before washing to help protect the surface finish and keep the black color vibrant.

  • Hang dry in shade or lay flat to dry to maintain the tee’s shape and soft, breathable feel.

  • Iron on low heat if needed, on the reverse side to avoid direct contact with the rainbow smily design.

  • Do not dry clean to preserve the softness and casual comfort of the muscle tee.

Storage:

  • Fold neatly or hang on a padded hanger in a cool, dry place away from direct sunlight.

  • Keep out of direct sunlight to help preserve the black color and fabric integrity.

  • Store loosely to avoid stretching the standard fit and to maintain the sleeveless shape.

Additional Advice:

  • Wash separately or with similar dark colors to avoid color transfer during the first few washes.

  • Promptly remove from the washer to minimize wrinkles and keep the soft, comfortable feel for active kids.

  • Handle gently during wear and washing to preserve the versatile rainbow smily design and clean black look perfect for styling with shorts or joggers.

Great Socks.
Color: (002) Black / Black / Halo Gray, Size: Large
These are awesome and have become my favorite socks to have for everyday wear. I have since bought the hightop version as well and there are just as equally great. They fit almost like compression socks. Color does fade a bit after repeated washing but not enough to make a big difference in appearance. They have lasted for a long time and still going. They have lots of cushion which makes it very comfortable to wear.

Great Socks
Color: (001) Black / Black / Castlerock, Size: Large
I keep ordering these over and over again. They fit well, and are soft and comfortable. My feet don't sweat like crazy while wearing them. The cupped heel makes them fit even better. They hold up to everything from everyday use to active lifestyles.

Good sock but thick
Color: (001) Black / Black / Castlerock, Size: Small
These Under Armour socks are high quality and definitely durable, with great cushioning and a solid fit that stays in place throughout the day. The material feels supportive and they hold up well after multiple washes without losing shape. My only minor downside is that they’re thicker than I expected. They feel more like a heavy-duty training sock, which is great for colder weather or intense workouts, but a bit bulky for everyday sneakers or warmer days. That said, the quality is excellent, and if you prefer a thicker, more cushioned sock, these are perfect. Just something to be aware of depending on how you plan to use them.
