Thank you for viewing. This is a Fairweather frame bag. It has been used once, but due to circumstances, I stopped riding and haven't used it since. Fairweather bags have several variations, and this one is the waterproof type made with X-PAC material. (There are some that don't use X-PAC, and I've seen them priced in the same range, so please be careful when purchasing. X-PAC has a diamond-patterned fabric.) Made in Japan, the use of X-PAC fabric, the good design, and the brand name, which means "fair weather," are also key points. As the cycling season is approaching, this frame bag is recommended for those planning to ride gravel bikes or cross bikes. *X-PAC fabric is a fabric developed by DIMENSION-POLYANT in the USA, known for its waterproof and abrasion-resistant properties. High-end outdoor brands like Mystery Ranch and Snow Peak use it in their products. Made in Japan Size: Length 25cm, Height 17cm, Width 8cm Weight: 92 grams (actual measurement) Material: X-PAC Capacity: 1.7 liters
