Source-linked specifications for the Cumulus the QUILT 300 — M / Standard / 900FP / Toray Airtastic. This is a detailed quilts 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
M / Standard / 900FP / Toray Airtastic is the recorded option. Other sizes or revisions may have different dimensions, weight, or test labels.
Reported specifications
Unit conversions are calculated from the source value. Open the source tag for the originally published number.
A blank or unverified value means the dataset cannot support a number; it does not mean zero. Each source tag opens the record used for that field.
Sizes and alternatives
Compare a size against its own record. Shared family names do not prove identical weight or dimensions.
