What temp rating

[Jmort1754]

Dad is buying a new bag he has an elk park from big Agnes but it's heavier than a railroad tie

Do all late season Colorado Wyoming bag---




Western mountaineering

Bristlecone -10

Or

Puma -25

I would go with a -10 bag. If you get cold you can always throw on a puffy jacket or pants assuming you would have those with anyways.

Don't forget a high R-value pad such as an Xtherm.

Hard to get one bag to do it all for winter. There will be a sacrifice on one end of the temp range or the other. It is possible to unzip a very warm bag and use it as a quilt for warmer thou.

He has a Klymit pad static v luxe sl says it's rated at 6.5.

Klymit's self-advertised R values are not considered accurate. The ASTM R value is accurate where provided. It looks like that specific bag does not have an ASTM rating, but based on other Klymit bags, I would assume an actual R value of around 3.

You can see the difference on this model as an example:

Klymit | Insulated Static V Luxe™ Sleeping Pad

The biggest and most comfortable inflatable lightweight sleeping pad at around two pounds, with synthetic insulation that keeps you warm at night.

I recently picked up a bristlecone. It's awesome. Can't imagine getting cold in it. Warmer weather finds me in my trusty terralite

Technically correct, but they are designed to be used with a down bag where the down will still expand into the gaps and be warmer. If you use this with a quilt with no insulation underneath it will absolutely under perform.

Sleeping Pad R-Values of 2024 - SectionHiker.com

A backpacking or camping sleeping pad's R-value measures its resistance to heat loss to the ground w

Kodiak MF 0 degree bag and a REAL pad. I love the comfort of my Klymit pads, but they are nowhere near their self-proclaimed R-value ratings. That pad has a TESTED R-value of 1.3. No amount of down in between baffles is going to make up that discrepancy. A Kodiak with an Xtherm or a Sea to Summit Ether Light Xtreme would be my recommendation. A -10 or -25 bag would be overkill for the lower 48, especially a quality bag like a WM or a Feathered Friends.

Pad is a very big part of keeping warm, best to test while at home to be sure it will work......if possible.

Eastern backpacker here. Do the thermarests designed for eastern backpacking work well for western? I’m hunting 3rd season elk in colorado this year and I’ve never even camped in the west before. I’ll be backpacking in.

I have a lot of eastern gear but I’m worried about my Thermarest being too thin for super cold nights.

I’ve been lingering on these threads for months. You guys are a wealth of great information!

Look at the R value. Higher the warmer.

I go this route. I'm a fan of layering to dial in the warmth you need.

Same with pads. I usually take a thermarest zlite for the extra r value and to protect the pad from puncture.
