Display text only on very specific WordPress urls ($_SERVER[‘REQUEST_URI’])

Hello!

I'm trying to display a block of text on a product category page. To cut a long story short the standard WordPress product_category functions aren't enough.

If the url if domain.com/c/vests/ is it possible to create an IF statement that incorporates the function $_SERVER['REQUEST_URI'] to check and only display information for that and only that exact URL.

For example:

Visitors who load the page domain.com/c/vests/ see a text block.

Visitors to domain.com/c/vests/?color=red etc DO NOT see the block.
