Last week I took delivery of two bags from SealLine, their Urban Backpack and Shoulder Bag. The first one I really will be testing out the next few weeks is the Urban Backpack. With its dry sack design and roll top it really is water proof. This right now is needed in the South East as it has been raining 3/4 days a week.
Both of these bags will be traveling across the country with me to Sea Otter which means at least one of them will be on my back for 8+ straight hours with helmet, shoes, laptop, camera gear, etc etc. I would guess probably around 15 lbs of gear.
