Brooks Tools Bag question
 

Just posted a few pics of my new Brooks B-17 and have a Brooks question. I may consider a Brooks Tool Bag. It would be a nice classic touch. I k ow that a Brooks saddle needs to be covered while riding in the rain but what about the tool bag? It the Proofhide adequate protection?

If you're carrying heavy tools in the bag it may stretch if it gets soaked. I'd just use a big plastic bag to cover both the saddle and bag if it's raining.
