“800-fill down set” would be a misleading way to summarize either of these matching outfits. Both reviewed jackets list 800 fill power, while the corresponding pants list 650. A shared collection name does not make their insulation specifications identical.
Keep four garment records, not one outfit specification
| Piece | Fill power | Fill mass | Garment weight |
|---|---|---|---|
| Down Transition Jacket | 800 | 145g | 13.6 oz, Medium |
| Down Transition Pant | 650 | 135g | 12.4 oz, Medium |
| Expedition Jacket | 800 | Not verified | 42 oz, size not supplied |
| Expedition Pant | 650 | Not verified | 35 oz, size not supplied |
Sources: Down Transition Jacket, Down Transition Pant, Expedition Jacket and Expedition Pant. The supplied records do not identify fill-power test standards. These are documented specifications, not measured warmth scores.
Three tempting calculations to avoid
- Do not average 800 and 650 into an outfit fill rating. The numbers describe separate fills in separate garments.
- Do not substitute total garment ounces for missing fill mass. Shell, fasteners and other materials are part of that weight.
- Do not label both collections waterproof because they are down outfits. Expedition lists taped construction and a 20K/20K claim; Down Transition describes DWR and treated fill.
For a bundle, verify each included piece, size and revision independently. A matched color does not establish the right waist retention or jacket shoulder fit. No current equivalent bundle-price comparison is established here.
