AllPro Unisex Pro-Lock Performance Long Sleeve T-Shirt

Built to Perform. Built to Print. Built to Last.

Most performance tees make you choose — great to wear, or great to decorate. The AllPro 48400 Unisex Pro-Lock Performance Long Sleeve T-Shirt refuses that compromise. Engineered from the ground up for athletes, teams, and decorators who demand both, this is the long sleeve performance shirt that shows up for whatever you throw at it — on the field, in the gym, or under a heat press.

The fabric starts the story. Constructed from 100% polyester interlock jersey at a clean 4 oz./yd², the 48400 hits the ideal weight for an active long sleeve — light enough to move freely without restriction, structured enough to hold its shape and keep your branding looking sharp. The interlock construction gives the knit a smooth, even finish on both sides, making it more refined and durable than standard single-knit performance fabrics.

Pro-Lock technology is the headline feature. AllPro developed this proprietary system specifically to solve one of the most persistent problems in decorated activewear: dye migration. In standard polyester tees, heat from the printing process can cause the garment's dye to bleed upward into the ink layer, muddying colors and degrading fine detail over time. Pro-Lock uses cationic disperse dyeing — a process that chemically binds color molecules deeper into the fiber — creating a truly bleed-resistant print surface. The result? Graphics stay vibrant, edges stay crisp, and your artwork looks as sharp after 50 washes as it did on day one.

Beyond decoration performance, the fabric delivers genuine athletic credentials. Built-in moisture management pulls sweat away from the skin and accelerates evaporation, keeping the wearer cool and dry during high-output activity. Snag resistance protects the fabric from pulls and pills during contact sports or rugged outdoor use. And UPF 50 sun protection blocks 98% of harmful UV rays — a must-have feature for outdoor training sessions, cross-country meets, endurance events, or any activity that puts your team in direct sun for extended periods.

The fit and construction details are equally considered. A self-fabric collar — made from the same interlock material as the body — offers clean, consistent structure without the bulk of a separate rib insert. The rolled forward shoulder seam is a subtle but meaningful ergonomic detail that repositions the seam away from the top of the shoulder, eliminating pressure points and allowing a fuller range of arm motion. Hemmed long sleeves finish the look with clean, durable cuffs, and a tear-away label keeps the back of the neck smooth and irritation-free while giving decorators a blank canvas for custom branding labels.

With 25+ color options — from clean neutrals like White, Black, and Charcoal to vivid options like Neon Orange, Neon Yellow, Lime, and Bright Pink — the 48400 gives teams the flexibility to match any color scheme. Heather versions of Navy, Royal, Granite, and Steel add visual texture for a more premium aesthetic. Available in a wide XS through 5XL size run, it's genuinely inclusive for co-ed teams and diverse group orders.

Whether you're outfitting a travel baseball team, a corporate 5K group, a school cross-country squad, or building a performance apparel brand from scratch, the AllPro 48400 delivers professional-grade results at a price point that makes bulk ordering easy.
