Boca Juniors Alternate 1984 Kits

Boca Juniors 1984 away white shirt is indeed a training white shirt! 100% cotton.

In 1984, Boca played Vs Atlanta at home. Atlanta kit was blue and yellow vertical stripes, with blue shorts and yellow socks (from adidas, too).

As referee's request, Boca should change its kit. But there was no away kit.

So, a pack of training t-shirts was used instead. Of course, the t-shirts had no numbers, so they were made with black ink water markers. During the match, sweat from players made numbers melt, creating ink stains. This embarrasing story ended in 2nd time. Boca had to use the home kit anyway, but Atlanta won the match.
