Colmic Colorado 3700 is the most spacious and impressive model in the Grey Essence series, engineered for those who require maximum carrying capacity and impeccable organization during long fishing trips. Its standout feature is the massive front compartment with direct access, designed to allow quick opening and a full view of the interior, facilitating gear management even in dynamic situations.

The lower section features a dedicated compartment holding four oversized plastic tackle boxes (larger than those in the 3600 model), which are fully customizable. On the sides, two large multi-purpose pockets with integrated mesh sleeves offer space for reels, clothing, or supplies. Built with top-tier plastic zippers and sliders, this backpack offers superior resistance to salt and humidity. Despite its size, comfort is guaranteed by a back panel with breathable padded inserts on the hips and lumbar area, combined with stabilizing shoulder straps. The rubberized bottom provides ultimate protection against water, mud, and abrasive surfaces.
