Patagonia, the outdoor clothing company, has just launched its EncapsilTM Down Belay Parka. Available in special edition quantities with numbered labels inside, the first of its kind parka is 100% independently baffled and differentially cut without a single shortcut where a seam has been sewn through, which could result in a cold spot.

Weighing 510g and insulated with plasma-treated, water- repellent EncapsilTM 1000-fill-power down, the belay parka is unparalleled in warmth for its weight, designed for alpinists to take into the burliest of conditions.
