PHD's 900 down expands the possible

"Our 900 down is the best we have ever handled in 50 years in the business"

PHD's 900 down, the best we have handled in 50 years in the trade, brings extra performance to Ultra, Yukon and Hispar gear and redefines the boundaries of Ultralight. Weightless travel? Not quite, but closer than ever before.

Read more on the story behind our exceptional down.

Down is magical stuff and none more so than this wonderful goose down, the best we have ever seen in fifty years of making down gear. Just handling it was exciting from the start and all our tests have confirmed its exceptional quality. So special is it that it has enabled us to offer our lightest ever gear without losing performance—in fact in some cases the gear is both lighter AND warmer than before.

900 down is STANDARD in:
Ultra Bag Ultra Vest and Pullover

345gm
+8C

150gm (vest)
230gm (pullover)
-5C
We have reduced the weight for the Ultra Bag and Vest while providing the same insulation as before. The Ultra Pullover follows the same design brief—minimum weight to do the job. The 900 down has taken the Ultra gear to a new level.

Yukon Jacket Hispar Jacket Hispar Bags

450gm
-15C

700gm
-25C

770 to 1720gm
-9 to -58 C
For both of these superlight jackets the 900 down has allowed us to save even more weight while slightly increasing the insulation. We have changed the whole Hispar bag range, extending it at both ends to form a selection of bags with the best warmth/weight performance possible at 'mountain' specifications.
900 down is an OPTION for:
Minimus Sleeping Bag Omega & Xero Expedition Clothing Xero down sleeping bags Diamir down sleeping bags
A reduced fill of 900 down provides the usual level insulation for less weight, bringing the total weight down to 425gm. 900 down reduces the weight and increases the insulation for all these items. The 900 option extends the range of these bags by up to 10 degrees C without increasing weight.
