WATERPROOF RAIN COVER: Our saddle cover is made of PVC material, lightweight yet very robust. This means the rain cover reliably protects the saddle from rain, snow, and dust. Even in heavy rain, the saddle cover remains perfectly waterproof.NO UNNECESSARY SEAMS: Many other saddle covers on the market have seams in inconvenient places that could allow moisture to penetrate. In contrast, this saddle cover has no unnecessary seams on the surface, making the cover truly waterproof.FITS ALL STANDARD SADDLES: An elastic band is sewn into the end to keep the saddle cover snug on the saddle. The elastic band is very elastic and has sufficient tension. This makes the saddle protector easy to put on and take off, and it fits any type of saddle. LIGHTWEIGHT & COMPACT - Our rain cover weighs less than 30 grams. It can be put on and taken off the bicycle saddle in just a few seconds, and when folded, it fits easily into your pocket. It's easy to store and fold, so you can take it anywhere.
