Cotopaxi Impermeo 3L Hooded Shell Jacket – Women’s
When the weather turns without warning, the Cotopaxi Impermeo 3L Hooded Shell Jacket is ready. Designed for coastal walks, mountain trails, and sudden summer downpours, this women’s waterproof shell delivers dependable protection without slowing you down.
Built with three-layer, fully seam-sealed construction, the Impermeo blocks wind and rain while maintaining breathability for active days outdoors. The two-way stretch fabric moves with you on the trail, and pit zips with mesh pocket bags allow quick ventilation when the effort ramps up.
Thoughtful adjustability throughout lets you fine-tune your fit, with an adjustable hood, hem, and cuffs that seal out the elements. Aquaguard® zippers, an internal storm flap, and a laminated hood visor provide extra defence in heavy rain. When the sun reappears, the jacket packs into its own hand pocket, making it easy to stash in a pack or day bag.
Lightweight, packable, and built for unpredictable conditions, the Cotopaxi Impermeo 3L Hooded Shell Jacket is a go-to women’s waterproof jacket for hiking, travel, and everyday adventures.

Measuring Tips
Use a flexible tape measure, and if possible, have someone help you take measurements.
Wear something light and close-fitting—like leggings and a t-shirt—so your clothes don’t add to the measurements. Don’t wear anything thick or heavy, like jeans or a jacket.
Stand up straight with your feet shoulder-width apart.
Chest
With the tape measure parallel to the floor, measure the circumference around the fullest part of your chest.
Waist
With the tape measure parallel to the floor, measure the full circumference of your natural waist (at the crease when you bend to one side).
Hips
With the tape measure parallel to the ground, measure the circumference of the fullest part of your hips (usually around the top of your thighs, where they connect to your torso).
Sleeves
Starting at the base of your neck, measure along your shoulder, then down to the wrist. Your elbow should be slightly bent.
Inseam
Holding the tape measure vertically, measure straight down from your crotch to the floor. Take this measurement without shoes on.
