Sometimes, mountain weather refuses to cooperate with your plans. On an August trip backpacking in the Wind River Range with my son, we saw patches of blue sky only on our first afternoon—followed by a couple of days of rain, culminating with us hiking out nine miles in a wind-driven tempest and temps in the 40s Fahrenheit. On days like that, I’m happy to have a shell that will reliably keep me dry and comfortable like the Zeta SL.
