I was surprised how much the 4.5L held when I expanded it to 6.5L for a day hike—perfect for stashing extra layers and snacks. The zippers feel solid and the pack stays snug against my hips even when fully loaded.

The MOLLE webbing made it easy to attach my water bottle pouch, and the expandable storage from 4.5L to 6.5L was perfect for stuffing extra layers on a long hike. Stays snug against my hips even when fully loaded.

I was skeptical about the expandable storage, but popping it from 4.5L to 6.5L on a longer trail day was seamless. The MOLLE webbing also gave me a spot to clip my jacket without messing up the balance. It's quickly become my go-to for quick scrambles.
