The Ascent 500 Sleeping Bag keeps you warm when the temperatures start to bite
What Our Gearhead® Experts Are Saying:
"I brought the Ascent 500 Sleeping Bag on a late September trip where temps dropped into the upper twenties overnight and woke up warm and comfortable every morning. The wide mummy cut is a real differentiator for anyone who finds traditional mummy bags too restrictive, and the Nikwax hydrophobic down held its loft through two nights of heavy condensation without any noticeable heat loss."
Shoulder season camping comes with unpredictable nights, and the Rab Ascent 500 Sleeping Bag is built to handle them without making you pay for a bag that is warmer than you actually need. With an ISO comfort rating of 34°F and a lower limit of 25°F, it covers the range of conditions that autumn and spring camping tends to throw at you, from mild evenings to genuinely cold nights that catch you off guard.
The 650-fill duck down is treated with Nikwax hydrophobic finish to resist moisture and hold its loft when condensation or damp air would otherwise compromise a standard down bag, and the 30D Pertex Quantum shell adds DWR protection from the outside in. A down-filled draft baffle along the 3/4-length zipper seals out cold air, and a 3D neck collar locks warmth in at the shoulders where most bags lose heat first. The generous, wide mummy cut gives you room to move without sacrificing the thermal efficiency of a fitted silhouette, making this a strong choice for campers who find traditional mummy bags too confining. Both a stuff sack and a storage sack are included, and the whole bag is built from recycled materials throughout.
