The widest of our 0 degree bags, the Ibis provides room in the shoulders while maintaining the efficient cut necessary to reduce extra space and keep heat loss to a minimum. Like the Snowbunting, the Ibis is ideal for cold ascents in the Cascades, Nepal treks, and for Mount Rainier. The Ibis also excels when you are pushing the comfort rating of bag and need space to wear a down jacket while you sleep.

EX: Winter & Expedition. Pertex® Shield® fabric. 15 denier with 40 denier rip-stop reinforcement. Water-resistant/ breathable coating.


  • Mummy shape (wider width) with #5 YKK two-way zipper with locking sliders
  • Pertex Shield EX water-resistant/breathable shell with DWR
  • Permanent collar with EX facing to prevent breath condensation from entering the bag
  • Continuous baffles let you position the down where you need it
  • 3D contoured hood wraps a layer of insulation around your head
  • Generous draft tube prevents cold air from seeping past the zipper
  • Includes storage bag & stuff sack


Mummy Sleeping Bags

Feathered Friends wide mummy sleeping bags have more space throughout, especially in the shoulders. This is perfect for those with broader builds, or those preferring to stash a lot of gear inside the bag.

I am 6'7 and heavy. I bought this bag to use as a top quilt for hammock camping. I was plenty warm during a Saskatchewan moose hunt in October. Temps got down below freezing almost every night. I like where the zipper stops as it makes for deeper foot bag. Good fill heats up quickly. Great piece of cold weather gear.

Great bags!!

This was my second bag from FF. I have a 20F Flicker and this Ibis. Both outstanding quality. Also have a Eos Hooded Jacket. Can't imagine using another company for down products.

Nice and cozy

I've had my Ibis sleeping bag out two nights winter camping so far. With overnight low temperatures around 25F. This bag hardly noticed that temperature and I slept very comfortably. This is a high quality bag that should be good for years of outdoor adventures.

2 nights in this bag so far. Night 1 test in the back yard was 33 degrees and rain ; tent leaked and I awoke 1am to sleeping in a puddle. Stayed in the wet bag until dawn just to see how the product could do in this circumstance. I was cold because the bottom of the bag was soaking wet; to be expected and hopefully won't be repeated in the mountains as this is supposed to be a winter bag for snow camping. Mostly I was impressed that the top of the bag remained mostly dry and still had warmth. Laid it out in my house for a day and then in the dryer with balls; it quickly dried out. Night 2; 22 degrees and gusty. Superior warmth ! I've never owned any bag rated below 20 degrees so this 0 bag feels WAY warmer than anything else. The loft is large, zipper works easily. Love the pull cord on the hood and the bungee pull on the draft collar. Plenty big for me 5'6" 175 lbs with a water bottle, boot liners, electronics, you know the stuff you gotta keep warm when ski touring. Plus I side sleep so the extra width is good for that. Such a warm bag in fact that it made obvious the only cool zones were between me and the snow; time for a winter sleeping pad upgrade. I use the 20 degree FF Flicker spring, and fall sometimes in summer backpacking and bikepacking.
