Released in 2013, this hoodie contains hypercolour technology, which was very popular in the 90's.
Hypercolour products change colour depending on the applied heat, they're 'thermochromic' - this hoodie goes from a blue to an off-white when heat is applied (from your hands etc).
Features a small tri-ferg on the brest and a large Tri-ferg print on the back.
This hoodie is in fantastic condition, other than one small stain to the front (circled in second photo). No damage to print or hoodie otherwise.
