Product Information "The Mountain Studio S-5 W 3L Stretch Insulated Jacket for Women Ephemera"

The The Mountain Studio S-5 W is the insulated women’s ski jacket in the collection: a three-layer ALP-3 stretch membrane, fully taped seams, and PrimaLoft Gold Eco insulation—60 g in the body and 40 g in the sleeves. The 4-way stretch fabric, made of 88 percent polyamide and 12 percent spandex, makes the jacket as flexible as a softshell while remaining water- and windproof. Ephemera is a light, muted shade of rosé.

The Mountain Studio S-5 W 3L Stretch Insulated Jacket for Women in Ephemera

The adjustable, helmet-compatible hood features a laminated visor for clear visibility in snowfall. The waterproof 2-way front zipper with Aquaguard technology, the snow skirt, and the integrated chin guard keep wind and snow out. Ventilation zippers under the arms release heat when it gets too warm during an ascent or in the spring sun. The High-Reach sleeve construction ensures that the jacket doesn’t ride up when using trekking poles.

Pockets and Details

One chest pocket, two hand pockets, two interior pockets, and a ski pass pocket on the sleeve. Cohaesive cord stoppers, removable vertical brand logo, signature sidecut at the hem. Repair kit included. The matching pants are the P-5 W in the same color.
