Uses the SummerLite for spring and fall high-desert trips and an AlpinLite for summer alpine trips. Was borderline too cold in the SummerLite on a windy canyon rim near Escalante in early March in a tarp tent, so would not take it for winter desert trips.
“TBH, I have been borderline too cold in the SummerLite on an early March trip to Escalante/Glen Canyon on a windy canyon rim. I was also in a tarp tent, so didn't have ideal wind protection.”
