I can't recommend any particular model, but I know it's tough finding a compromise between a lightweight pair that's easy to carry, vs. having a large enough exit pupil. Especially if you plan to use them for kayaking (where you won't be able to hold them perfectly still) and in lower light forest conditions, you'll want a larger pupil.

I'm not 100%, but I'm pretty sure these are the ones we have down south. They're a bit out of your price range, though. I've been happy with them for birdwatching, but haven't brought them on the 'yak.
