Northants chief executive Ray Payne has hailed the County's new contract with Canterbury as 'the most significant kit deal in the history of the club'.
A three-year deal, which will run until 2020, has been agreed, meaning Alex Wakely and Co will wear the Canterbury kit across all formats from the start of the new season.
Canterbury supplies playing apparel to many teams around the world, from grassroots to elite, as part of their dedicated teamwear business.
And Payne said: "We’re delighted to be bringing a brand like Canterbury on board - they’re a great company and their clothing is quality.
"It is the most significant kit deal in the history of the club.
"I’ve seen the kit and it looks fantastic.
"There will be a brand new shirt design for 50-over cricket this season as well as a new training kit and then next year we’ll also have a brand new T20 shirt.
“But it’s not just about first class cricket. It is about the Northamptonshire Cricket Board, and the Canterbury brand will flow all the way through the club from the second eleven and Academy right down to those involved in the player pathway and youth divisions.
Supporters will be able to purchase replica merchandise from the club shop at the County Ground from today.
