Rangers fans have praised Castore after being blown away by new training products that debuted at Firhill on Monday night.
The Gers took on Partick Thistle in Maryhill in their first pre-season fixture and triumphed 1-0 courtesy of an 83rd-minute Cedric Itten goal.

20 outfield players received 45 minutes of playing time with established stars, fringe players and youth prospects all getting their first runouts since the summer break.
Despite it being an away fixture, the Gers wore their new 150th anniversary year home strip, which received rave reviews.
However, new never-before-seen training gear attracted even more attention.
Prior to kick-off, the Gers’ official account tweeted, ‘New season. New training gear’, alongside pictures of Jack Simpson and Jay Hogarth modelling two different pieces of kit.

The white t-shirt worn by Hogarth is already on sale online and in the Rangers stores, but this was the first time supporters had clapped eyes on the navy and orange 3/4 zip worn by Simpson.
Earlier, the squad had also arrived at Firhill decked out in a previously unseen full grey tracksuit (bottoms already available).
The overwhelming reaction to the new products was positive, with fans urging Castore and the club to make them available to buy as soon as possible.
Here’s a selection of reactions from Twitter:
