Size & Fit Guide
Finding the perfect fit is key to comfort, whether you're cheering from the stands or playing on the pitch. Please use the guide below to help you select the best size.
1. Choose Your Fit
Fan Version (Regular Fit): Designed for everyday wear. It has a slightly looser, more relaxed cut. We recommend buying your standard size.
Player/Authentic Version (Athletic Fit): Designed for professional play. It features a tighter, more "fitted" cut. We recommend sizing up if you prefer a less restrictive feel.
2. How to Measure
To find your best fit, take a jersey that you already own and that fits you perfectly, lay it flat on a table, and measure:
Chest Width: Measure from armpit to armpit.
Length: Measure from the highest point of the shoulder to the bottom hem.

Email Customer SupportAt Pro Kit Vault, we are committed to getting you game-day ready. We operate an intelligent logistics framework to deliver your jerseys quickly and safely, wherever you are.
Our sorting centers work tirelessly to pick, quality-check, and pack your gear. Most orders are fully processed and shipped out within 1 to 3 business days.
Partnered with reliable elite air couriers, our shipments take an average of 7 to 15 days to land securely at your doorstep, complete with end-to-end tracking.
To fulfill our brand guarantee of speedy global delivery, Pro Kit Vault manages multiple logistics fulfillment nodes strategically placed across major international hubs.
Once your checkout sequence is completed, our automated routing engine immediately detects your destination coordinates and assigns the shipment to the nearest global warehouse housing your selected sizes. In the event that a specific jersey style or custom size is temporarily out of stock at your local facility, our team will instantly trigger an internal stock transfer from our next nearest backup vault to fulfill and dispatch your order without unnecessary friction.
We understand that anticipation runs high for sports fans. That is why we enforce a strict 1 to 3 business days standard fulfillment window to finalize order packages.
• Standard In-Stock Kits: Dispatched reliably within 24 to 72 hours.
• Personalized/Customized Jerseys: May require up to 3-7 business days, as our senior printing technicians apply specialized precision hot-pressing and custom hand-stitching alignments to ensure professional-grade durability.
*Note: Order processing times may experience subtle extensions during massive global tournament windows, Black Friday peaks, or high-volume festive seasons.*
Our primary shipping networks provide tracked express logistics to over 90 destination countries. Once your package is handed over to the air carrier, standard transit times average **7 to 15 days** globally.
We provide full step-by-step transparency. The moment your parcel crosses our sorting terminal gateway, an automated shipment dispatch alert containing your trackable courier airway bill number will be pushed directly to your registered email address.
While our shipping lines utilize optimized postal lanes to accelerate clearance sequences, international packages cross multi-border legal boundaries.
Deliveries targeting specific countries or remote regions may occasionally face unpredictable logistical delays due to strict local customs processing protocols, border backlogs, or localized agricultural/security random screening routines. These protective clearance procedures are legally governed by the destination nation's border agencies and remain completely outside the jurisdiction and control of Pro Kit Vault. We appreciate your understanding and patience should your package experience a localized customs hold.
It is the buyer's sole responsibility to ensure that the inputted shipping street data, zip codes, and recipient contact numbers are absolute and free of typos. Pro Kit Vault cannot issue refunds or cover carrier return fees if a parcel is rendered lost, undeliverable, or returned to sender due to insufficient or incorrect address entries provided during checkout.
If your tracking code hasn't updated or you need immediate assistance regarding a customs notification, our specialist fan support team is on standby to assist you.
Contact Us Page Email SupportFan Version (Regular Fit): Tailored for casual everyday wear and comfort in the stands. It features embroidered logos/crests and a slightly looser, standard cut. We recommend ordering your normal size.
Player/Authentic Version (Athletic Fit): The exact same high-performance kits worn by the athletes on the pitch. It features a slim, body-contouring fit, lightweight heat-pressed badges, and advanced breathable ventilation meshes.
