Product Description

The RAB Ascent 500 Regular is a lightweight, mummy-style sleeping bag designed for three-season use. It’s built to keep you comfortable on cool nights, with a women’s comfort rating down to +1°C and a men’s comfort limit of –5°C.

Inside, it’s filled with 650FP RDS-certified European duck down treated with a Nikwax fluorocarbon-free hydrophobic finish, so it holds warmth even if damp. The 20D Pertex Quantum ripstop nylon shell sheds wind and resists tears, while the 20D recycled nylon lining feels soft against your skin. At 215 cm long and 80 cm wide, it’s sized to suit campers up to around 185 cm tall without excess fabric getting in the way.

Fill power (650 FP) indicates how much loft the down provides—higher numbers mean better insulation for its weight. RDS certification guarantees responsible down sourcing, and the hydrophobic finish helps prevent moisture from clumping the fill. The ripstop weave in Pertex Quantum adds durability by stopping small tears from spreading, so the bag stays reliable trip after trip.

RAB says about the Ascent 500 Regular

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 our 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.

Practicalities are taken care of with an internal zipped stash pocket that easily fits a phone or a headlamp, a cotton storage sack, and a compression stuff sack to ensure a manageable pack size and protection on the road. Exploring with a partner or want extra space? Pick up a left and a right zipped bag and you can zip them together.
