Clothing company Jack Wills have started a new social media campaign, with the objective of raising vital funds for a UK brain tumour charity Brainstrust.
The #ShowUsYourTackle campaign encourages guys to get in their Jack Wills underwear, take a picture, and upload it to Instagram using the hashtag #showusyourtackle and tagging @JackWills in the post.
For each picture posted, Jack Wills will donate £1 to Brainstrust, to ensure that the charity can continue in providing support services to people who have been diagnosed with a brain tumour.
Here is a selection of out favourite contributions to the campaign thus far.
