Mountain Hardwear - Phantom 30F/-1C

That’s a nice collection! How is phantom 32 working for you? I loved it but the down clumped on me. Couldn’t fix it with tennis balls etc and MH finally agreed to honor warranty for it

The new stuff is way too expensive for me. I have five of their older models and they are still chugging along just fine. A Speed 32, a Phantom 32, a Phantom 45, a Lamina Z Flame 22 and a Wraith -20. I think one of their new top of the line 0 degree bags costs more than what I spent on all of the ones I own.

Mountain Hardware Phantom 32, down bag, packs down to the size of a football, but expensive. In any case, go with down, as it is more compressible.

Late to the Party, but the Mountain Hardwear Phantom bags are no longer a good value proposition (not to imply that they were before), but you can get a Western Mountaineering Kodiak MF (Microfiber) for $850 or the Storm Shield Version for $985. The Phantom Windstopper 0 degree starts at $1,100. Western Mountaineering is made in the US and so some of the tariff-related inflation is not hitting them as hard, making them a better value proposition. Not to mention Western Mountaineering makes the best down products in the world. Other folks have mentioned Gryphon Gear. Another awesome option. You may need to wait a while to get one though. Feathered friends is great too but I think Western Mountaineering is amazing. My recommendation, Get a Kodiak MF. The Microfiber fabric may look unassuming at first, but it is incredibly durable, tightly-woven fabric with excellent weather/water resistance and it breathes super well, critical for multi-day winter outings. I have a Puma Storm Shield and while I love the fabric and the fortress feel, a laminate fabric like that takes a long time to pack into a stuff sack. It just traps air like a balloon. The microfiber is a dream fabric. A proper microfiber fabric where the filament count is equal to or higher than the denier of the fabric.

The difference between the Phantom and the Bishop Pass is weight - they're both down bags, but use different fill powers to achieve the same temp ratings at different weights. Phantom -18C weighs 2lbs 10oz and the Bishops Pass -18C weighs 3lbs 2.1oz. Not a huge difference for the price, but if weight is a major concern it could be worthwhile. FWIW I've got the Phantom in -40 (non goretex), -18 and a Ghost Whisperer -9 and they're great bags. My wife has the -29 Lamina and it's fantastic, just heavier and bulkier than the down offerings. I wouldn't hesitate to get the Bishops Pass if it fits your budget and you don't mind the few extra ounces. You can use the extra $$$ to pick out something else on their website.

My current down mummy one from Mountain Hardwear that I got for a crazy deal (<$90). There are zippers on both sides and the toe area. I move a lot in my sleep, and the slightly wider area up top makes it easier. (It's wide enough for my arms to go to my shoulder area, even zipped up.) It's a huge step up from my previous one, a cheap synthetic mummy.

It's really a personal choice. I would suggest you try the MH sleeping bag. It's a free way to test a type of sleeping bag. Worst case, you buy another one later. I personally use down sleeping bags because they are lighter and compress better. But they are more expensive and take a lot longer to dry if it gets wet.
