Source-linked specifications for the Rab Ascent 700 — WR. This is a partial 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. The recorded comfort figure is 28°F (-2.2°C); verify the exact size and test method before planning a cold night. 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
WR is the recorded option. Other sizes or revisions may have different dimensions, weight, or test labels.
