The Rab Double Pile Jacket, as the name suggests, uses double layer Berber pile fleece across the back to deliver excellent warmth. The chest & sleeves are lined with a polyester micro-fibre to give protection from the wind & to add comfort when worn over a tee shirt. this may not be the lightest fleece in the world & it may be a bit bulky, but when you just want to chuck on a toasty warm & reassuringly weighty fleece the Double Pile Jacket takes some beating. Featuring two hand pockets & an internal security pocket the Double Pile Jacket is simple yet effective.
