Review relates to Hispar 600 Sleeping Bag
"This bag has an unmatched warmth/weight ratio ... The draft tubes undoubtedly provide the best insulation behind the zip of all the bags tested – not a trivial detail if you face harsh conditions."
— from Carnets d'Aventures Magazine's test of 18 sleeping bags for cold conditions.
Review relates to Yukon Down Jacket
"Many thanks for the jacket that you supplied me for the Yukon Arctic Ultra. [It] performed perfectly in temperatures down to -35°C. The light weight and small size was also a huge help and helped me gain second place in the race. I ... am now the second fastest person over the course and the fastest European."
— Dr Stuart Gillet (wearing a prototype Yukon jacket).
Review relates to Rondoy Down Trousers
”The lightest 'big mountain' down legwear that PHD has produced. They use 950 fill down, water-resistant Ultrashell face material and have full-length side-zips for ease of use. Serious cold weather trousers.”
— OutdoorsMagic Review.
Review relates to Minimus Down Socks
"The solution to cold feet."
— Mike Smith, on Trip to Greenland's 'North Liverpool Land', April/May.
