Ri-Dry jackets - are they that good?

[asset2004]

As per the title, would like reviews of a Ri-Dry jacket. At roughly £150 I think it's an awful lot of money for a rain coat.
A few people, including myself, in our hunt wear the long waterproof waxed coats when it's really wet. I think they can be good as they help keep the legs dry too (although wearing waterproof breeches isn't too much of a problem.)
I also like that they keep the worst of the rain off my precious saddle.
But waxed coats are not warm, so I have lots of layers and fleeces underneath.

So going back to my original question, are they that good?
And what is the sizing like?

I am usually a size 8/10, and looking at the size guide wondered if I could fit into a large childs as it's £40 cheaper. Has anyone else tried this?

I love mine, would happily buy another I wear mine with their waterproof cream breeches. I do wear layers under it, but loads of room, and I do feel the cold!

I can't help with the childrens sizing though - I am a size 8 but I need the adults for the length of arm.

Thanks LJR good to know you'd buy again.
Re sizing, I'm not very tall so hoped the childs would fit however did you order a small? Or would I be best with a 12 to allow for layers?
Do you wear it over your hunt coat? As the sizings suggest it should be.
I don't think I'd wear it over my hunt coat as I've so many layers may struggle to move.
CJR could you tell me the length of the arms please? Thanks

They are designed to be worn true to your size but over a hunt coat. So I wouldn't go up to a 12. Also they really should be worn over you hunt coat, so that you are wearing it out hunting.
