Custom Woocommerce theme parallax issue

Hi guys
I'm developing a theme for use with Woocommerce and having a few issues with the Parallax effect..

Weirdly, this particular issue is only happening on Woocommerce pages so I guess it's a conflict of Woo's js or css somewhere!?

Take a look at this page, the parallax section works fine at any width of viewport (on a desktop browser - it's disabled for mobile devices):

However, on a Woocommerce product page, the parallax section has a margin on the right for any viewport less than 1500px.

Any ideas? It's driving me crazy
Thanks in advance
