SEO Advice for my Ecommerce Product Description Pages

Hi,

We own a Mens Clothing Online Store namely Pudu Lifestyle. Currently the template has a provision for Short Description and Long Description and we are pasting the same information for Short as well Long Description as observed if you see in any of our Product Urls.

Example

http://www.pudu.com.au/explorer-mens-cotton-peached-canvas-shirt.html

Both Short & Long Description is filled with the same content.

Now Is this going to hit the SEO of the page?
Would you advice us to completely remove the below “Product Description” Tab?

Please advice the strategy to adopt to improve seo of Product Description Pages.

Thanks,
Nuk

Your short alt text is - well a few words. And for you long text, imagine you are on the phone with someone who will Never see the item, how would you describe it to them? Should they match probably not.
