For starters, Mountain Smith outfitted this pack with an adjustable torso length, making it relatively painless to dial in the perfect fit. The back panel consists of EVA foam with ventilation panels and a mesh-lined hip belt for cool and comfortable carrying. Behind the Lariat's simple looks lies a feature-rich design with a large roll-top closure, additional U-shaped front panel access point, and detachable summit pack for multi-day summit bids. The Lariat is also equipped with a hydration sleeve with hose port and side water bottle pockets, if you'd rather pack water bottles than deal with a reservoir. Last but not least, Mountainsmith made this pack from heavy-duty Cordura nylon fabrics, ensuring longevity and hard-wearing performance season after season.
