High elevation climbing and mountaineering objectives have a certain way of throwing unexpected weather at even the most experienced alpinists. For this reason, it's helpful to have a ‘stay-warm-no-matter-what’ type of layer in your pack at all times, just in case of the unexpected. This is where the Axion Pro Down Jacket comes into play, thanks to heavyweight insulation and a packable design. The 700 fill down insulation boasts superior warmth-retention and a Nikwax hydrophobic finish to ensure moisture doesn’t interfere with its insulating properties. The jacket packs down into the included stuff sack to ensure that you always have room for it — just incase.
