Quick weight question for an upcoming trip

[Kat]

8 lbs just for their pack? Mine weighs less than 3!

Yeah, this is the big problem I personally have with goat saddles! Somebody needs to build an ultralite one  But, you can cut that by at least 2 lbs by going with a Sopris Rookie saddle & intermediate panniers.

You could use a Bearikade Blazer (50 ci bigger) instead of Bear Vault 500 and save another half pound.  http://www.wild-ideas.net/the-blazer/  

Then you're into the smaller items to save weight, just an example your scale at 142g, mine only weighs 91g.  It all adds up.
