10 trekkers (5 men and 5 women), who are not linked to Quechua, tested this down jacket for a week of trekking in November 2016, in the Mont Blanc mountain range. The feedback given to us after this test have enabled us to validate this down jacket for mountain trekking.
All our gilets are laboratory tested with 5 km/h wind, worn as a 2nd layer on a thermal mannequin (over a long sleeved t-shirt). Their level of thermal insulation is measured on a scale of 1 to 5, enabling you to make the choice that best fits your use.When worn underneath the TREK 500, it can provide 6°C extra warmth when compared to a down jacket worn without gilet.
