Rain pants


Reviewed By: Marilyn on 6/28/20

I got them for our tour in the Dakotas but never used them, so I guess they were good for weather insurance. They are roomy but not too long (in size small). I am still glad I bought them.

Wanted a bright pair of rain pants that could be used on or off the bike. These fit the bill plus they are inexpensive and worth a try. I am 5'1" , wear a size 8 or 10 and needed the small because they do run big and can easily fit over clothing (cycling or everyday wear). I have no idea how durable these are.

Useful pants in a pinch

The O2 pants could be useful in a downpour but for me I’d have to use them with suspenders. They are inexpensive and lightweight and noticeable but they take up some volume and I’m told they are not very durable.
