The Sport-Tek YST101 Youth Competitor United V-Neck is one of three tops in Sport-Tek's coordinated Competitor United system, all built on the same 3.8 oz PosiCharge poly interlock with UPF 30+ sun protection and the signature contrast colorblocking that gives the family its unified team look. The YST101 specifically is the V-neck option, which is the silhouette youth soccer teams, basketball squads, and volleyball squads have been reaching for over the crew-neck version. It reads more athletic, more jersey-adjacent, and the colorblocking at the neck and side pulls the design forward from a plain performance top. At around $11 MSRP, it's the youth athletic top that ends up looking like a real uniform rather than a team-colored tee.
V-neck versus crew: which one is right for your team?
The three Competitor United tops (crew, V-neck, and the henley in the broader Competitor family) all use the same fabric, same colorways, and same decoration behavior. What's different is the neckline, and that shapes both the aesthetic and the intended use case. The crew (YST100) is the most familiar and versatile pick, and it's what most PE classes, baseball teams, and general youth sports settle on. The V-neck (YST101) reads more athletic and more like a soccer jersey or basketball warmup, so it's the more common pick for those sports specifically and for any team that wants a slightly more finished, less "gym class" look. If a team's aesthetic matters (and for a lot of youth programs it does more than the coaches admit), the V-neck is where the extra thought shows. It's also the top that pairs most naturally with the YST103 shorts we mentioned earlier, since both share the side colorblocking design language.
The construction, in plain language
The YST101 is 3.8 oz/yd² of 100% polyester interlock (a smooth, tight-knit fabric that lays flat, holds shape, and takes decoration cleanly) with Sport-Tek's PosiCharge color-locking treatment built into the yarn. The neckline is an athletic V-cut with contrast colorblocking, and the side panels carry the same contrast color, which is what visually ties the shirt to the matching YST103 shorts. The label is tear-away. Youth sizing runs XS through XL. If you're new to the PosiCharge story, it's Sport-Tek's fabric technology that locks color into the polyester yarn so both the shirt itself and any decoration you put on it stay vibrant through repeated washing rather than fading toward gray, which is the reason the Competitor family is a workhorse for team decoration.
UPF 30+ and what to know about the coverage
UPF 30+ blocks over 96% of UV radiation, which is the American Academy of Dermatology's threshold for genuinely "good" sun protection. That coverage matters on tops more than most other athletic apparel because the shirt covers the shoulders, upper back, and chest, which are the surfaces that see the most direct sun during outdoor sports. For a youth soccer game on a Saturday afternoon, a summer camp field day, or a t-ball practice, the YST101's UPF 30+ is a real layer of protection, not a marketing claim. If your team plays in genuinely extreme sun (all-day tournaments in Arizona, Florida water-adjacent camps, Caribbean-latitude programs), Sport-Tek's Posi-UV Pro line steps up to UPF 50+ but is only offered in crew tees, not V-necks, so there's a tradeoff between silhouette and maximum coverage there.
Coordinating the full uniform
The YST101 is designed to work as part of a system rather than as a standalone top, so the other Competitor United pieces are what you'd stock alongside it. For the matched bottom, the YST103 Youth Competitor United 5-inch Short uses the same 3.8 oz PosiCharge fabric with matching contrast colorblocking on the side panels, which is exactly the design element that ties the V-neck and the shorts together as a coordinated set. For teams that prefer a crew-neck silhouette on their top, the YST100 Youth Competitor United Crew is the sibling in the same fabric and family (colorblocking on the shoulders instead of the neck and sides). And for coaches and adult staff on the same team, the adult ST101 Competitor United V-Neck is the matched adult version in the same fabric and design.
If a team wants a broader Sport-Tek performance top selection beyond the United line, the YST359 Youth Competitor 2-Button Henley is a related pick in the same broader PosiCharge Competitor family, with a placket-and-buttons detail that reads a step sharper than a V-neck for teams that want to differentiate the coach's shirt from the players'.
Decoration
The YST101 decorates the way most Sport-Tek PosiCharge performance tops do. Screen printing works cleanly with the PosiCharge fabric holding color under the print, and heat-applied transfers (TPU, TPL, DTF) are strong picks for team-specific numbers, names, and logos because they hold sharp edges on the polyester surface. Embroidery is less common on athletic V-necks (the fabric is thin and the neckline construction limits placement options) but works on the chest or sleeve. The important caveat directly from Sport-Tek's spec sheet: given the extreme heat required for sublimation, consult with your decorator before running sublimation on the YST101, and sample test the fabric by color before committing to a large production run.

Questions buyers ask
Why V-neck instead of crew for a youth team?
The V-neck reads a step more athletic and more jersey-adjacent, which is the aesthetic soccer, basketball, and volleyball teams tend to want. The crew (YST100) is the safer, more versatile pick for general use, PE, and sports where the shirt is more incidental to the game. For teams that care about how the uniform looks on the field or in team photos, the V-neck is worth the small aesthetic upgrade at no meaningful price difference.
What holds the "United" system together?
Three things. First, the fabric: every piece uses the same 3.8 oz PosiCharge poly interlock, so they wash, shrink, and hold color as a matched set. Second, the color palette: the whole line ships in the same core Sport-Tek colorways, so a red team is red across all three pieces. Third, the design language: contrast colorblocking is the visual signature, and it's placed intentionally on each piece (neck and side on the V-neck, shoulders on the crew, side on the shorts) so the family reads as one line from across a field.
Does the YST101 have an adult version for coaches?
Yes. The ST101 is the adult Competitor United V-Neck in the same fabric and design, running adult XS through 4XL. For a mixed team order where the kids wear YST101 and the coaches wear ST101, the two decorate identically and look like one uniform.
What's the practical UPF 30+ coverage during a game?
UPF 30+ means the fabric blocks at least 96.7% of UV radiation, which the AAD identifies as the threshold for "good" sun protection in clothing. The V-neck covers the shoulders and upper back, which are the surfaces getting the most direct sun during an outdoor game. For most youth outdoor sports contexts, that coverage is real and meaningful. For genuinely extreme sun exposure, the Posi-UV Pro crew tees step up to UPF 50+.
Can I sublimate a team logo onto the YST101?
Yes, but with care. Sport-Tek specifically flags in the spec that sublimation on this fabric requires the extreme heat that polyester handles differently color-to-color, so a sample test by color before a production run is worth the small extra step. For custom team designs where every player has a name and number, sublimation is a genuinely good pick; just build in the sample test.
