From the field
What players and parents are saying
★★★★★"I wasn't sure what to expect for $25 but these sleeves have held up through two full weekends of tournament ball and still look brand new. My son won't take them off."
★★★★★
"Fits perfect and looks great on the field. Ordered a youth large for my 10-year-old and it's exactly right."
Chris R. Youth Large Travel ball
★★★★★

Marcus T. Youth Medium
★★★★★
"Three kids on the team asked where he got it at the first practice. The shark does the work."

Before you ask
Questions parents actually ask
What size should I order?
Measure around the widest part of your bicep and match it to the size guide above. When in doubt, size up — the spandex blend stretches and holds, so a slightly larger sleeve stays comfortable all day.
How do I wash the sleeve?
Machine wash cold, gentle cycle, inside out. Lay flat or hang dry — avoid high heat in the dryer to keep the spandex performing at full stretch. Do not iron or bleach.
Does it work for pitchers and position players?
Yes — the sleeve is position-agnostic. Pitchers wear it for arm warmth and muscle support between innings; position players wear it for sun protection, compression, and the look. Works for either.
Do you ship internationally?
We ship across the US with a low flat rate. Returns are available on domestic orders only.
What's covered under the 30-Day Guarantee?
Any defect or failure under normal play within 30 days of delivery — stitching, seam failure, elastic breakdown. Send us a photo and we'll replace or refund, your call. Damage from misuse or improper washing isn't covered, but if something goes wrong on our end, we make it right.
