Both Marek and his craftsmanship are a rare gem of a find for someone looking for a stylish and functional bike frame bag. Marek is extremely nice and quick to respond with any questions. The bag is if the highest quality leather and a perfect size, but what really makes it standout is the design looks simple yet is completely thought out and constructed to be so functional without seeing any unnecessary decoration and considers all of s bikers needs like slim width so it doesn't rub your thighs while riding, and also big enough for s u-lock and some personal effects. If you're looking for a stylish bag this is a great one at a great price
I love that it can be detached and used as regular bag. There are few places to improve, but it's already really good as is and looks nice.
