Cyclists, this one's for you! The M-Wave Rotterdam bag attaches right to your bike's top tube so your phone (even big ones like iPhone X) is always accessible but totally protected. The clear window on top is genius - you can actually use your touchscreen through it while riding, and it's water-protected so rain or splashes won't mess with your phone. Three strong Velcro straps keep it securely in place no matter how bumpy the trail gets. There's even shock-absorbing padding inside to protect your device from vibrations and impacts. The material is water-repellent and the zippers keep everything dry. Plus, there are reflectors on the sides for extra visibility when you're riding in low light. Measuring 18.5 x 9.5 x 8.5 cm, it's roomy enough for your phone plus maybe some keys or cards. Unisex design works for everyone. Seriously, if you use your phone for navigation or tracking your ride, this bag makes life so much easier and safer.
