Actually, I don't think the inner material is even waterproof. It certainly wouldn't cope with more than a short light drizzle. It's only meant to be used on it's own in fine conditions - ie. no rain. You could take it if you were happy to sleep in the huts if there was any chance of rain. But I'm not sure there are any nights on the OT where where there is zero chance of rain, so I guess that's not saying much.
If you wanted to save weight you could take just the outer and combine it with either a bivy or a groundsheet and bug net, but you wouldn't save much weight that way.
Oh, I just found on-line that Hilleberg describe the inner material as "highly breathable and water repellent" - doesn't sound like "waterproof" to me - it's likely to be a lightly-DWR coated ripstop nylon.
