Could someone give me a hint about database design:

Say I have a database with products. I have names, prices, category, etc.
I want to add tech. specifications to my products. For every product there are at least 8-10 specifications and values.

For example:

name: Wide Leather Belt

Tech. specs:
weight: ?? kgs.
color: ???

Is it better to keep them in the same table with the product, or separate?
