Sopiba, 0.5 L ruokateramari mahtuu pysttyssä.
A good bag for everything a small back needs all the time. Not a very sturdy solution even with a small weight, bounces a bit, but it's not meant to carry heavy stuff inside. However, it does not come off thanks to the lock.
Easy to attach and stays in place.
High quality, as you expected. A couple of times on a longer Bikepack tour and with Packraft. The bag is attached to the Canyon Grail bike and fits perfectly. The mounting part for the bike to remember to buy separately, I myself have a lockable model.
Ortlieb's Six Free is high-quality, light and easy to use. I bought it for my wife who wanted a bag for her business trip of about 20 km that can hold the most important ones like a little windbreaker, a keychain, a wallet, etc. The bag can be easily removed from her rack. The mobile phone fits practically well on top of the bag in a plastic pocket.
Bike bag very functional. Challenges with installation, as the brake and gear cables prevent the bag holder from being installed in the desired position. The bag is slightly in front;)
