BUFFALO SYSTEMS Mountain Jacket

METHODS
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.

Design Thoughts

The Mountain jacket is used by the military, police and Scottish mountain rescue. The three-quarter-length design provides excellent coverage and two-way double zips means it can be unzipped from the bottom for comfort when seated. The Pertex outer is renowned for extreme wind resistance (50mph) and the AquaTherm pile lining feels instantly warm to the touch. The jacket has two external and two internal zipped pockets. These are only half pile lined, which is a little disappointing. Elasticated waist and hem adjusters reduce draughts, and a Velcro band on the collar allows attachment of the modular hood (sold separately), which is a nice feature.
Test Results

The Mountain jacket retained 55 per cent of the heat, meaning insulation properties were similar to the Avid and TFG jackets. However, the pile lining felt much warmer to the touch than all of the other jackets, which had smooth nylon linings. Being a three-quarter-length jacket meant it was always going to be heavier and bulkier; the size 44 weighed 910g and packed down to just over eight litres.
PROS Extreme wind resistance and warm to touch.

Three-quarter length provides extra coverage. CONS High price. Pockets could have been better finished.


Price: £179
