Geosmina's top tube bags are made of Nylon 600D and Hypalon with seams sealed with high-frequency welding technology. Nylon 600D is completely waterproof and has an external PU (Polyurethane) coating that repels water and makes the bag dry quickly when in contact with the air. The bag has a TPU (Thermoplastic Polyurethane) coating that, together with the sealed seams, makes the bag completely watertight. The YKK zippers are waterproof. The interior is reinforced with a chassis that stabilizes the bag and protects the load from possible shocks. The internal chassis can be removed in case you want to use the bag to carry larger items. The bag is available in two sizes: Small with 0.5 litres and Large with a capacity of 1 litre. All top tube bags feature the brand’s logos in reflective material for better visibility and 1 set of zipper pulls in two colours so you can give it the look that you personally prefer. The bag also has a front outlet for cables such as the battery of your bike light or a power bank.
