I recently bought a Palm drysuit and really like it (except for the fact that it doesn't have a relief zipper, but that's my purchasing decision, not their fault) after three uses. The times I've worn it, I've had good feedback from others regarding their personal experience with other Palm products. Personally, I'd go for a drytop, not a semi-dry... you can always roll to cool off. I had an IR w/o a latex neck and it was good for about a season with not letting water in. After that, it was a chilling experience of cold water rushing down my neck. I ended up soaked and chilled even on warm days. I then bought a real drytop. Wish I had skipped the expense of the other.
