Evaluation
The Hyper PuffTM jacket forms an effective protective layer around the body and provides uniform insulation. Its construction is somewhat stiff and inflexible; however, the arms allow unhindered freedom of movement. The hood is generous and warm, but creates a slightly odd shape when the draw cords are pulled tight. The sleeve cuffs are interesting and extra warm. The sleeve hem is turned inside at the ends and has a wide stretch band that traps heat well (see detail shot). It has a warmth-to-weight ratio of 7, which is very good in relation to other synthetic fibre jackets, although the pack size is on the larger side. The jacket comes with a drawcord stuff sack, which can be tied to a zipper so as not to lose it. It has a total of four pockets: two side pockets and two inner pockets (one made of mesh).
Conclusion
Warm insulation with uniform insulation performance throughout the jacket and innovative cuffs.
Suitable for :
- Thick winter insulation jacket for wet and cold days.
- Very warm mid layer if worn under a larger hardshell.
Evaluation
R-Value
The R-value, or thermal resistance, is the capacity of an insulating material to resist heat flow. It is measured using a standard test method according to ISO 11092. The higher the R-value, the greater the insulating power.
Coverage
The surface area of the jacket is measured. This is done using the image processing program ImageJ. The larger the surface area of the jacket, the more of the body it covers and the more protection it provides against heat loss.
Weather protection
This test is conducted by our outdoor testers. The test criteria include waterproofing, windproofing, protection provided by hood, sleeve length and cuffs and seams.
Pack size
The jackets are compressed in a measuring container and weighed down with a four-kilogram weight to simulate compression, for example, as in a backpack. The result is measured in litres from the measuring container scale.
Weight
Weight is measured using a precision balance.
Freedom of movement
Freedom of movement is tested in a range of different activities, such as hiking, climbing, via ferrata and everyday use. How easy the jacket is to move in? Does it restrict? Does the hem lift?
Warmth-to-weight ratio
The R-value, or thermal resistance, is the capacity of an insulating material to resist heat flow. It is measured using a standard test method according to ISO 11092. The higher the R-value, the greater the insulating power.
Strengths
