This daypack takes a nod toward alpine packs, with a light-yet-strong ripstop shell coated with a TPU film and Durable Water-Resistant finish. Heavy-duty molded padding gives the shoulder straps and back panel a comfy ride, and there's a webbing waist belt for additional stability on tough trails. A tube port lets the laptop sleeve double as a hydration sleeve, and there are side stretch pockets for water bottles.
