Source-linked specifications for the Rab Ascent 900 — Women's Regular. This is a detailed sleeping bags record, checked on 2026-10-30; price and live stock are not verified.
What the specs mean
The product name or temperature label is not automatically an ISO comfort rating. An independently comparable comfort number is not recorded for this variant. Treat a manufacturer label as a shopping description, not a safety guarantee. Fit also depends on usable internal length, shoulder room and your sleeping position. Pad insulation and weather matter as much as the bag.
Read the exact variant
Women's Regular is the recorded option. Other sizes or revisions may have different dimensions, weight, or test labels.
