The Blackburn Barrier Micro saddle bag is everything a basic saddle bag should be. At first you clearly notice its clean, minimalist, welded-seem lines. It is very light and small - just the right size for a road tube, tire levers, patch kit and a CO2 inflator with cartridges.
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.
