An insulation jacket featuring highly insulating padding. The padding, which incorporates aerogel for superior insulation, provides excellent warmth even though it's thin, and offers a comfortable, lightweight feel. The convertible design allows the sleeves to be removed, enabling it to be worn as a vest. Removing the dot buttons under the armpits of the convertible section also provides ventilation. Furthermore, it can be attached to a ZIP IN ZIP compatible jacket. The outer fabric is water-repellent ripstop nylon, which handles light rain and snow. The hood is built-in. It can be stored compactly and comes with a stuff sack for convenient carrying. This is a versatile item that can be used in many ways. Search terms: Nuptse Mountain Jacket Baltro Light
