I started with an 8 man kifaru and got a 12 man soon after. I got about 150 nights out of each before they each started to get UV 'failure'. I sent them both back multiple times for repair and Kifaru repaired them for free. That said I did retire both tents and moved on to Ti goat and Seek outside teepees. Currently I use a cuban fiber (DCF dyneema) seek outside tent and it has been outstanding. My impression so far is that dyneema is more resistant to UV. Patrick
