Cheltenham-based casual clothing brand, Weird Fish, has launched its latest range of T-shirts for the RSPB.

Building on its existing partnership with the nation's largest nature conservation charity, Weird Fish is boosting fundraising efforts by donating £5 from every t-shirt sale to the RSPB. Each of the new tees features a graphic print bird design.

The women's Flight RSPB Graphic T-Shirt (£20) is available in white and grey marl colours. It is a comfortable fit, with a crew neck and colour pop stitching to bring it to life.

For men, the Swallows RSPB Graphic T-Shirt (£20) includes a majestic swallow design across its chest for a 'swooping' statement, in a choice of two colours.

Katy Terry, Corporate Partnerships Manager at the RSPB, says, "We can't think of a better time to launch these wonderful t-shirt designs than spring; when nature comes to life and bird species including swallows start to arrive in the UK. Every £5 donation will help us to protect the nature that we love and depend on."

The latest RSPB t-shirts follow the brand's 'Weird Birds' t-shirt launch back in February, with Weird Fish raising over £135,000 for the charity since first partnering in 2015. The new Weird Fish RSPB Graphic T-Shirts are available online now.

Weird Fish was founded in Cheltenham in 1993 and aims to bring that weekend feeling to customers through all of its clothing. It has 15 stores around the UK and started selling its clothing online in 2005.
