Hi,
I have a Hexamid Twin with the extended beak and twin size CF groundsheet with 5 inch bathtub floor but, alas, have not had a chance to use it since I bought it, so can't comment on it's ability to handle humid conditions. [Have had a very busy work year and, on the two overnighters I've been able to do since I bought the Hexamid we've used camp caves].

The design works well as long as you can pitch the entry facing away from the weather. The extended beak will help alleviate this issue - the front of the Gatewood Cape is much lower to the ground and I had only one night in an extreme thunder storm that caused a little spray to enter theHexamid Twin with the extended beak and twin size CF groundsheet with 5 inch bathtub floor shelter. I also used a MLD cuben tarp on the AAWT last summer. It worked well but a beak would have improved it so I would certainly recommend getting a beak. I am just about to buy some cuben from Zpacks to make one for the tarp. I certainly think that cuben is better material than sil-nylon material for shelters with low weight, almost zero stretch and great waterproofness. For other gear I am not yet convinced.
Mark F, I was very interested to hear that you used your Gatewood Cape on the Haute Route. I appreciate that conditions are very changeable in the mountains and vary with altitude, time of the season and from year to year but, given your time over, would you use the Gatewood Cape again for the Haute Route? I'm planning on doing the Tour Du Mont Blanc (full circuit, 10 - 11 days) at the end of June next year following a work trip (a little earlier in the season and a little lower in altitude than your trip) and was considering taking my Hexamid as my shelter (not yet decided whether to tent it, stay in the huts etc or a combination of the two). Curious to hear your thoughts. (Will obviously see how the weather is at the time before making a final decision). Would definitely like to do the Haute Route another time!
Cheers,
JB
