Rab Microlight Vest Features:
If core insulation and freedom of movement are high on your list then the Rab Microlight Vest could be a great solution. Lightweight, weather-resistant and packed with 750 Fill Power Hydrophobic Down this insulated gilet provides core warmth for a range of activities on or off the mountain as well as for day-to-day use. The stitch-through construction with mini baffles retain heat reduce cold spots while the 3 pocket configuration adds to the versatility of this classic down vest.
Great fit and design, I went for this one as it has a pocket on the front which is ideal for your mobile. The only negative is it does let more down through the lining than other makes I've had, especially if you have a backpack on.
