A Gloucestershire-based casual clothing brand has raised £100,000 for the RSPB since its partnership began in January 2015.

The money has been raised through Weird Fish's limited edition T-shirts, designed exclusively for the charity. Over the years, £5 from the sale of each T-shirt (typically on sale for £20) has been donated to the RSPB, the UK's largest conservation charity.

There have been 10 T-shirts since 2015 in the clothing brand's RSPB charity range.

John Stockton, managing director at Weird Fish, said: "We are delighted to have helped raise £100,000 for the RSPB. Our partnership has been very successful and we have plans for more exclusively designed T-shirts to continue to be released. We have the utmost respect for the work the RSPB does in securing a healthy environment for wildlife."

Birdvinci is the eleventh T-shirt designed exclusively for the RSPB. The design pays tribute to Leonardo da Vinci's Vitruvian Man and is available in a variety of colours.

Designed by artist Richard Skipworth, this T-shirt is the latest addition to the range and kick-starts Weird Fish's continued support of the charity for 2019. The new T-shirt is on sale now for £20, with £5 from each T-shirt donated to the RSPB.

Katy Terry, corporate partnerships manager at the RSPB, said: "We are really proud of our partnership with Weird Fish. Thanks to their support we have achieved this fantastic milestone and look forward to developing more pun-tastic T-shirts that will raise vital funds for the RSPB; helping us to address the many challenges facing wildlife at this time."

Birdvinci is available to buy nationally from Weird Fish retail stores and online. Weird Fish plans to reveal two more surprise designs that are in the pipeline for 2019.
