Timbuk2 is having a sale right now. I've been using their bags with domke inserts for years now. They are bullet proof and very weather resistant. Worth a look. I saw this and it peaked my interest. Paired with this $20 Tenba insert and it's the perfect bag. It's got insulation and paired with the Tenba insert you'd have a lot of protection. Just thought I'd pass it along... p.s. It also has an attached bottle opener.
