I am looking for a warmer pair of pants for hiking, climbing, birding, and photography. I run cold so even with warm upper body layers I will be cold in the 40s/50s as soon as I stop moving especially in the wind/shade.
My main fall outdoor pants have been the Prana Stretch Zion so I am looking for something warmer. I am considering the Gamma LT or the Activator 3.0. I would really love to NOT wear an extra layer(ie SmartWool tights) while climbing as it always feels like I am inhibiting my movement.
1)Which of these is warmer?
2)How much warmer is the Gamma LT compared to Zion?
3)How much warmer is the Activator compared to Zion?
4)Any other advice, comparisons, or product recommendations?
Thanks
