SD.

I've had Gore-Tex and numerous "coated" rain gear and they all have their weak points.

I read where my fellow QJers have had rain gear they paid big bucks for fail them miserably or didn't live up to the hype.

Read my gear review about the British Military surplus Gore-tex pants. They have a jacket in the same pattern but it's not as cheap.

One thing to remember about military surplus items. Some have been used but a lot of it was NEVER issued.  The military has strict standards that the vendors have to meet. You can get high-end gear for discount prices.

Those surplus pants I bought served me well thru an all-day soaker. I've had rain pants with side leg zippers, both knee and waist high and they ended up leaking on the zipper areas in a heavy rain.

I opted to try the KISS method this time. Those British pants have a wide elastic waistband with a heavy duty elastic cord/toggle. Ankles are heavy elastic, pulled on easy over my water shoes because they were designed to pull on over combat boots in the field.

Something to consider. Even if you decide they are not what you want for a canoe trip, for the price they would make an excellent fishing boat or camp pant.
