Got caught in a sudden downpour with my gym clothes in this bag and everything stayed bone-dry inside, the polyester really holds up. The 18 inch size fits a full change of clothes plus my sneakers with room to spare.

The drawstring closure is sturdy enough for daily gym trips, and the polyester handles the sweat and dampness without soaking through. Only gripe is it’s a bit thin if you’re stuffing it full, but for the price it does the job well.

The drawstring bag does exactly what I needed for a rainy commute, and the polyester held up fine against a light drizzle without soaking through. Only minor gripe is the straps feel a bit thin if you load it heavy, but for basics it's perfectly fine.
