Rays Outdoors has a special for members (free to join here on Outdoor Expedition 650 Loft Goose Down Jackets, on sale for $100 (down from $249).
They're available in store, free click and collect or variable postage costs on checkout if you need it delivered.
I picked one of these up last Sunday for my husband and the sale finished that night but I saw they were on special again, thanks to Big Trev's post. We got the jacket instore at Majura Park, ACT and weren't members so they signed us up on the spot.
Kathmandu currently has a similar specced 650 loft goose down jacket on special for $225 (RRP $499), but that was more than we wanted to spend.
There's black, rust and blue marle in the men's and black, purple and white/cream (this colour I couldn't find online) for women. The men's blue marle was a thin silky fabric like Kathmandu/Uniqlo ones but the black and rust ones are a thicker, more sturdy fabric. Not sure about the ladies ones, but I'd assume the black may be the same sturdier fabric as the men's.
Only good reports so far, very warm for night dog walks in Canberra. Size wise my husband is normally a medium-large, but he got a large to allow enough room across his shoulders and to fit a thin jumper underneath for layering.
Would it be warm enough for Everest?
