All about this product



The Ascent 500 is a versatile bag with a comfortable, wide mummy fit. Filled with 500g of 650FP duck down and with space for wearing additional layers if needed, this bag can be used in cool temperatures. Ideal for two season use and spring conditions similar to those in the UK, New Zealand or Scandinavia.


The Ascent is built with a lightweight and durable, recycled Pertex Quantum outer fabric and recycled nylon lining. It has trapezoid shaped, boxwall baffles that stack neatly together, encouraging the hydrophobic duck down inside to loft fully and reducing the appearance of cold spots. Hand-filled in the UK, all Rab down bags benefit from never having had their down compressed before use, maintaining the down’s loft and warmth.


The generous mummy fit with wide foot box provide a spacious feel for an easy night’s sleep, and the close-fitting neck baffle keeps the heat in when the temperature drops. It has a ¾ length main zip with a down filled baffle to keep out the draught. Exploring with a partner or want extra space? Pick up a left and a right zipped bag as the Ascent Regular and Long length versions have compatible zips so you can zip them together.
