PHD Mountain Software

For complete weather protection these trousers are made with 2 layer Tempest fabric and fully taped outer shells. They provide an efficient hassle-free alternative when the full warmth (and weight) of salopettes is unnecessary.

"I purchased an Omega trousers from PHD about two years ago, which I absolutely love!!!! They were perfect for my 7 week trip to Mt. Vinson and the South Pole"

HS2 has now replaced Tempest as the standard outer fabric for the Omega Trousers, making them lighter, more waterproof and more breathable than before. Tempest remains an option for trips where extra durability is the most important factor.

†Please note: we make our stuff sacs big enough to allow fairly easy stuffing rather than reducing the trousers to the tightest minimum. What air is left in the packed item will easily be compressed out of it, if you are squashing it into a small space in your rucsace. Tiny stuff sacs look impressive: but unless you are a sac-wrestling fan, fighting the gear into them day after day can be an unncecessary chore.
