Pertex Quantum Pro neck baffle fabric for better moisture management.

The Rab Ascent Pro 600 down sleeping bag is designed with a spacious wide fit, ensuring that mountain explorers get the restful sleep they deserve after a long day. Filled with 600g of 650FP duck down, it provides ample warmth, even offering room for additional layers if temperatures take an unexpected dip.

The Rab Ascent Pro 600 is not just about warmth; it's about protection. The Pertex® Quantum Pro outer layer offers resistance against wind and water, making it a formidable barrier against the elements. Whether you're facing wind, condensation, or damp conditions, this sleeping bag stands resilient, making it perfect for an exposed bivi ledge. The trapezoid-shaped, boxwall baffles are meticulously designed to allow the down to fully loft, ensuring maximum insulation and minimizing cold spots. And with the down being hand-filled in the UK, you can be assured of its quality and longevity.

For added functionality, the Ascent Pro features a ¾ length main zip with a down-filled internal baffle and a 3D-shaped neck baffle, both meticulously designed to retain heat. An internal zipped pocket ensures your essentials, like a headlamp, are always within reach. And if you're looking to share warmth or need more space, you can easily zip together a left and right-zipped bag.
