The High Andes and Patagonia is famously windy. Hilleberg tents have a good name but the Nallo 2 is the lightest of their 2 person tents. We wanted the lightest but we wanted to improve its performance against very strong winds.
John Biggar an expert on the Andes says you need rock loop to hold up your tent not pegs as there is often no soil to hold pegs but there are mostly plenty of rocks.
We have added rock loops to all guys. The bottom right picture was a hasty setup to show how rock loops work on our lawn. There is a closeup, note the plastic ring, some guys nearly sawed through against a titanium tent peg in a gale in Scotland whilst testing. The plastic ring should be gentler as a rub point on the guy.
We have added 5 new guys 2 at the front and 3 at the back the top row of photos shows these. The idea is to support the fabric more frequently and get more tension on the middle of the tent front to back. Petra Hilleberg by email told me that the fabric should be tight front to back.
We have adapted our old style Nallo to the newer back vent system by adding a zip. There is a photo open for warm none windy weather and a one closed with another peg point.
I am very impressed with the internal guys we have added. The middle row of photos shows these internal guys. The bits that get in the way are removable so they only need to be there in strong winds. The front one is totally outside the inner so is only in the way when cooking and then not very much. The rear one is well over our feet in our sleeping bag. It does not get in the way of normal activities.
The internal guys allow the external pole guys to be much tighter without distorting the hoops. They support the down wind side of the tent. When you try and shelter from very strong winds behind rocks, some times you get viscious eddies that blow directly downward on the tent. These internal guys resist the hoops from breaking from that direction too.
Some extra guys could put local stress on fabric that was not designed for it. We have added strong elastic bungee tensioners to allow some give. The narrow photo is a close up of this tensioner. There are 6 on the tent
