To test the insulating properties of the garment, we measured the cooling rate of a bladder of warm water placed in the centre of the jacket. We filled plastic bags with 500 millilitres of water at 50ºC and used aquarium thermometers to take in-situ temperature measurements of the water in 15-minute intervals over a two-hour period. Pack size was measured by putting the jackets in a 20cm-diameter stuff sack and compressed with a 5kg weight. The jacket was then weighed with calibrated scales.
Reviewed in February’s Gear Guide Special, the jacket uses Snugpak’s Softie Premier sheet-style filling and features a three-quarter-length design with extended sleeves so it doesn’t ride up when casting. However, it would have been nice to get a two-way zip on a longer jacket like this. Its elasticated cuffs, hem and hood can be cinched down to further retain heat. This is the only jacket on test that features a built-in roll-up hood, which is a nice feature for keeping you toasty. Alongside the zipped hip pockets, it also has zipped outer and inner pockets, which are useful for storing personal items. It’s supplied with a stuff sack for ease of packing.
The Fortis FJ6 had excellent insulation properties, being second best on test by retaining 58.7 per cent of the heat. The jacket is also the heaviest on test at 970g (XL) and packed down to 9.3 litres. This is to be expected due to its added length and hood.
PROS Excellent insulation properties. Three-quarter-length design and a hood provide increased coverage. CONS A bit heavier and bulkier.
