Original Hilleberg snow pegs! They cost you a kidney, but are worth it! The tent itself is a bomber and it takes a lot of effort and/ or stupidity to destroy it.
We have various Nallo's (2,3 & 4) - very similar design. Only do 3 season camping tho'. Nammatj will have better head room at the 'far' end.
Confidence inspiring - just don't worry what the weather is going to throw at you .
Also a doddle to put up
Comparatively heavy tho'
