M's Barrows Jacket

I expected to overheat on the climb, but this thing breathes way better than my old shell. The water resistance held up through two hours of sleet and my core stayed dry the whole time.

Wore this on a wet, windy hike last weekend and my core stayed dry the whole time — the breathable membrane really does its job. It's warm without feeling bulky, and the water just beads off the shell.

The temperature swung from freezing gusts to sunny breaks during my last climb, and I never had to unzip once beneath that breathable shell. Moisture just wicked away while the warmth stayed locked in, even when I was sweating through the steep sections.
