The MTN Guide MW Hybrid Jacket offers ideal insulation conditions for summer. We have utilized our proven body mapping to combine two of the best performance technologies into an incredibly versatile product. The synthetic Primaloft® Gold Active Plus+ keeps your body warm even in damp conditions, while Polartec® Powergrid™ on the forearms and back provides temperature regulation and comfort, whether you're moving quickly or carefully contemplating the next steep slope. For all-day comfort, it is your ideal warmth layer for a summer high in the mountains. This hybrid jacket offers maximum heat-insulated versatility for summer, adapting to the conditions and keeping you moving without the need for multiple layers.
