Good quality at a decent price
If you're value oriented like me and cross shopping this with all the cheap, generic $10 rain covers on Amazon, do yourself and favor and get this one instead. The material is noticeably thicker while still being lightweight and just higher quality overall. Plus the drawstring closure feels more durable than the cheap nylon buckle straps and it can be cinched down tight. Sizing is difficult with this kind of product, but my local REI store allowed me to try these on my backpack to find the right one. I have a very boxy non-hiking backpack measuring about 50L in volume when fully packed (18"H x 12"W x 14"D) and this small size fit perfectly.
