I have had the slx mark 1 for 3 years and its still going strong and it's been used A LOT and thought about getting the slx v2 just because it has a peak, I just spent two months in Wigan and I was melting inside my bivvy because I was wearing a full dress suit and full thermal underwear it was very hot, That made my mind up that my next bivvy would have proper coat hooks like my brolly (jrc stealth ll) because the cats can climb through the vents which is so much better in the heat, But as we don't get much sun over here i would say yes get one.
