In reply to Euan McKendrick:
I've had a Lhotse for five years and it's OK, not as waterproof as I'd like, but they never are after a few years. One thing to note is the arm length. I've got six other ME jackets in Large, down, synthetic and softshell, and the Lhotse is the only one where the arms are super-long, like about three inches too much. Might be worth trying one on before buying (I got mine online without trying it first), as I found the extra length a bit of a pain tbh, although I've got used to it.
