LightHeart Gear Rain Pants

Great pants, limited sizing.

Silicon coated nylon with polyurethane treatment waterproof to 2000mm of water head. Zippers on the legs for easy on and easy off. Not in the least breathable, but very waterproof.

Not much to say, you put them on when it rains and you don't get as wet.

The big downside is that they come in fixed sizes with an inseam of 31 inches for extra small, 32 for small, and 33 medium to XXX-large, making them very long for anyone under 5'9". You can order custom inseam, but a $50 charge on a $69 item seems a bit disproportionate.
