Rae 捲頂防水袋 - 黑瑪瑙色

I've been using it every day for my commute to the gym, and the roll-top seal keeps everything bone dry even in a downpour. The waterproof nylon feels sturdy without being stiff, so it folds up small in my locker when it's empty.

Finally ditched the grocery-bag pile in my gym locker for this, and the waterproof nylon feels tough enough to survive anything I throw at it. The roll-top closure is so straightforward I can seal it one-handed after a swim.

The roll-top seal is genuinely watertight—I stuffed it with wet gym clothes and not a single drop leaked onto the car seat. The nylon feels tough enough to survive years of abuse, and honestly it's replaced my entire pile of plastic bags.
