Why We Like The Bishop Pass GORE-TEX Sleeping Bag

We're adventurers and we're always on the go, so we need a bedroll that can keep up with us like Mountain Hardwear's Bishop Pass GORE-TEX Sleeping Bag does. Being built with a GORE-TEX Infinium Windstopper membrane gives it greater resistance to those places where the weather has a tendency to get wet and windy. And while the winds howl and the rain beats down on the tent, we know we'll stay cozy and sleeping right thanks to the fluffy 650-fill down and heat-trapping design.


  • Sleeping bag for comfortable rest in temperamental weather
  • GORE-TEX Infinium Windstopper halts entry of water and wind
  • 650-fill down provides soft and lofty warmth to lull you asleep
  • Nylon face fabric is lightweight but lends long-lasting durability
  • Performance Plus mummy cut stays close to you for efficient heat
  • Shaped draft collar to stop cold coming in and heat going out
  • Anatomically shaped footbox better wraps your feet for cozy toes
  • Two-way zipper gives you the ability to keep ventilated

Outstanding bag, for the right conditions.

I own several sleeping bags, and have worked in the outdoor industry. My belief is most people shopping for a sleeping bag to be used in cold, wet weather, are likely going to be fine with the regular Bishop Pass, a terrific bag in it's own right, and not need Gore Tex. This bag is best used in very damp conditions. Be that a backpack in the Olympic Rainforest, or perhaps at altitude when the temperature hovers around freezing but there is high humidity, and dew and frost from condensation cover almost everything (this happens in mountaineering a fair amount). Or if you love sleeping cowboy style, or under a tarp. If you use a tent, that is going to do the trick for the majority of people reading this. Another factor to know is there are sleeping bags that are treated down, and/or a treated shell. In fact, one can buy a regular Bishop Pass, buy Nikwax Down Proof, and treat it yourself in a good, front-loading washing machine. This will make the bag somewhat hydrophobic, allowing moisture from condensation to bead right off the bag, or help the down keep from clumping even in high humidity situations. A few other key elements to clear up. While this is GoreTex Infinium (Windstopper) it is still 99% waterproof, almost exactly like regular GoreTex. It has a very effective membrane to keep water out. The seams are not taped, but the bag is effectively waterproof. While it is GoreTex, the fear that it will not breathe and you will overheat is mostly unfounded. Unless you are doing pushups in your sleep. It breathes plenty well. There is another misnomer that the bag is not as soft as other bags, this too is false. It actually feels quite nice, subtly brushed ripstop nylon. The cons? It's slightly more heavy than a regular Bishop Pass. In fact, you can find a quality 0 degree down bag that weighs less than this, for the same cost. It also does not compress as well, or small as a similar bag that is not GoreTex. It does however come with a compression sack.

Doubt Bishop Pass is as good as advertised

I don't think the bag is good to 15 degrees. at 32 degrees i had to zip everything tight to stay warm. At 15-20 degrees i think you would need to be fully dressed with wool or long johns to be warm

Solid bag - unsure yet if the Goretex is worth it

Solid sleeping bag. I was on the fence between this version, and the version without Goretex, and while I haven't had opportunity to test the moisture/wind resistance elements of the bag, I have been pleased with my choice. The bag is plenty warm, and the interior neck baffles are a nice touch that keep the lower torso warm even if your head is out and exposed. There is a pocket on the inside that is too small for phones, but for this type of bag, that isn't a chief design consideration for me. The Goretex version of this bag does not compress as much as the non Goretex version, and this bag is heavier, but there is an included compression sack that works well to compress it down and seems strong. The fabric on the inside of the bag is quite comfortable. I am 6'2" and the Long length felt just slightly long, but on the other hand, the regular would have likely felt too short. Overall, pretty pleased with the bag. I'll revisit the review when I've had a chance to use it in conditions where the Goretex would shine.

Cozy bag

I've used it once or twice and have initial impressions
Size Bought:
5' 9"

Works great for shoulder season hammock or tent camping. Blocked the wind very nice and was almost sweating on a very windy 38° night in my hammock.
