The Blackburn Barrier Small saddle bag is everything a basic saddle bag should be. The Small is wedge-shaped to efficiently use most of the space under the saddle. At first you clearly notice its clean, minimalist, welded-seem lines. It is very light and Blackburn's "Small" is big enough to hold a couple road or mountain tubes, mini tool, tire levers, CO2 cartridges as well as some other items.
Blackburn uses coated 420d TPU coated nylon that is ultra lightweight, water repellent and very strong all at the same time. Welded seams are employed to reduce bulk, weight and materials. They improve performance by eliminating the needle hole, a potential area for saturation and leakage. Welded seams also create a clean finish on both the interior and exterior of the bag.
