BALL PROPERTIES
FIFA Quality Pro • International Match Standard
Almost all DERBYSTAR models of the APS and TT series are either of FIFA Quality Pro quality or conform to the International Match Standard (IMS), which corresponds to FIFA quality. They can be used in all matches on an international level. All tests are conducted by a neutral body in accordance with FIFA rules. Tests include circumference, roundness, bounce, water absorption, weight, loss of pressure and—especially for FIFA Quality Pro—shape and size retention.
CATEGORIES & QUALITY LEVELS
Derbystar’s football RANGE offers balls in various qualities, weights and sizes. Or to put it another way: the perfect TOOL for every area of APPLICATION! below are brief descriptions and explanations of THE MARKINGS ON our balls.
ADVANCE PERFORMANCE SYSTEM
APS stands for Advance Performance System. It characterizes our balls and constitutes DERBYSTAR’s highest product quality.
TEAM-TRAINING
TT stands for Team Training. For almost every match ball, DERBYSTAR’s ball range offers a corresponding high-quality training ball.
In THE aps MATCH ball and tt training ball categories, footballs are divided into three quality classes:
PROFESSIONAL PREMIUM
PROFESSIONAL
STANDARD
"LIGHT" ODER "S-LIGHT" (SUPER LIGHT)
Our weight-reduced youth balls are marked as “Light” or “S-Light” (Super Light). Characteristic for these footballs are the blue design for “Light” and the red design for “S-Light”. Light footballs weigh 350-370 g, while S-Light footballs weigh 290-310 g. There are no consistent rules in Germany as to which ball is recommended for which age group and there are differences between different regional associations. An overview of the recommendations of regional associations can be found here.
LIGHT
Our footballs with the “Light” marking are special, weight-reduced youth balls. Our Light balls always carry a shade of blue in their design. With a weight of about 360 g, they are ideal for players in E and D leagues.
S-LIGHT
Our footballs with the “S-Light” marking are special, weight-reduced youth balls. Our S-Light balls always carry a shade of red in their design. With a weight of about 300 g, they are ideal for players of E and F leagues as well as Bambinis.
DOUBLE-LOCK-VALVE
Since air can only escape through two locks in this valve, the double-lock valve ensures optimal airtightness and prevents the ball from losing air too quickly.
PLAYERS NUMBER
All footballs of the APS and TT series have a player’s number field. By blacking out parts of the digital “88”, any one- or two-digit number can be created, so balls can be easily customized.
32-PANELS
All our balls have a classical design with 32 panels. The 20 hexagons and 12 pentagons provide optimal roundness and give the ball perfect aerodynamic properties.
ZERO-WING BLADDER
Our zero-wing bladder made of high-performance natural latex gives the ball an optimal round shape and a lively bounce.
REDUCED BOUNCE
The greatly reduced bounce is a special feature of our futsal range. If the balls are dropped from a height of 2 m onto firm ground, the bounce can amount to maximally 50-60 cm.
