Who This Product May Suit
This top may suit buyers looking for a rash guard or compression base layer for training, sparring or other active use where stretch, close fit and sweat-wicking fabric matter. It is also relevant if you need a choice of long sleeve or short sleeve versions.
When to Consider a Different Option
Consider a different option if you need a looser fit, a different sleeve length, or a size outside the stated age guidance. Buyers who want a general casual sweatshirt style rather than a compression rash guard should also look elsewhere.
Before You Decide
Confirm the sleeve length, size and age guidance before choosing an offer. Check whether you want the long sleeve or half-sleeved version, and make sure the close-fitting compression style matches your intended use.
