Any ultralight sleeping bag liner in the market?

[Besalu]

Hello:
I would like to experiment with a SOL Escape Bivy with the lightest sleeping bag liner that I could find. Any recommendations? What ultralight liner would you recommend? suggestions are appreciated. Thank you.

You can't get much lighter then a Silk liner. That and the bivy might be good down to 70.

I've used Cocoon Silk Mummy liners. About 4 or 5 oz, but rather pricey.

Enlightened Equipment sells one that's lighter than silk.

Thats not goin* to be so warm when the average is 50* at night in the Summer.

The Escape Bivy weighs about 8.5oz and a silk liner weighs about 4.5oz for a total of 13oz

An Enlightened Equipment Revelation 50deg in reg/reg 10D weighs about 11 oz and compresses down to slightly larger than a softball.

Far better option, IMHO

I didn't know that EE makes a bag liner. They do make a sleeping pad cover.

I would borrow one from someone and try it. Your long underwear (that you carry anyway, right?) will keep the bag clean, and you as well - and maybe as warm as the liner.

Lightest I’ve found is the Dutchware quilt liner. Holds up well for 2.5oz.

I bought a Borah cuben bivi a few months back...haven’t used it in any cold weather yet. How much warmth you think it adds? Think it’s the argon top version around 6oz...

Aren't you planning a hike on the Colorado Trail?
Please get a clue. The Colorado Trail is at high altitude. Much of it at 11,000'-12,000' or more. You may encounter rain, sleet, snow or hail and high winds at anytime or any day of the year. Do you know what that means in terms of survival?
If you want the liner and bivi for a tropical location, I apologize.

I've got the SOL Escape Bivvy and a Cocoon Ripstop Silk Liner (4.3 oz/122 g with stuff sack). I went with this liner for durability, but if you can get by without ripstop construction there's a lighter (100-110 g) silk liner here.

I haven't considered using these without a sleeping bag, but with the right clothing this might be a viable sleeping system. Layers work. They don't have to conform to any particular formula if you can get your combination to trap air, not trap moisture, and reflect body heat.

Give it a try and let us know how it works out. If these two layers also require puffy jacket and pants to keep you warm, you've just moved around the ingredients of a sleeping bag.

I sleep under a cotton sheet and a fleece blanket at 70 degrees. At HOME!

Expensive, but also the price varies dramatically on the Cocoon brand over time and by color. I paid $58.25 for my green (olive) version; I could have saved 32¢ if I'd waited for the current sale at Outland USA. Other current best prices are $84.90 (cornflower, sunset colors) and $45.63 (white).

A silk liner adds noticeable warmth. I slept in mine under an eiderdown quilt and felt the difference. Having said that, I'm not taking one with me as I should be warm enough

[Besalu]

Do they make 50° Revelation?

[Besalu]

Oh, no. The bivy is a separate issue. For the Colorado Trail I am bringing an Enlightenment Revelation 30° for sure!

[Besalu]

The Escape Bivy with liner is for another summer setting, not for the Colorado Trail. For that I am bringing my Enlightenment 30° Quilt.

[Besalu]

For the CT I am bringing the Enlightment30° Revelation quilt. The bivy is for warm summer trips.

[cmoulder]

Do they make 50° Revelation?

Yes, I have one.

Made to order, options HERE.

Click on "Sizing and Specs" to get actual weights... I have 4 EE products and find the info to be consistently accurate.

However, in that same size and temp rating the Revelation Apex weighs less than 12 oz and is a good option if a lot of moisture will be encountered.

Hey, Salty I don't know about the Borah bivy, but for comparison I have a clone of the ZP Splash with a Momentum 90 top and for me it adds about 10 deg, although it also covers the head area, which is a factor to consider vs the Borah. I've used the Rev 50 (mentioned above, with Klymit inertia xlite) at 43 deg in fairly windy conditions (25-30 estimated), with the tarp knocking down the wind a little, and was completely warm.

You are an experienced ULer so you know this can vary greatly.
