Thru-Hiking with Scars says:

Thanks for the thoughtful review, one thing to keep in mind is that cold weather sleeping bags are rated based on use with an insulated pad. Even your EE quilt will be cold if you stick with a ZLite (2.6 r-value), because you are a tiny warm spot on a very large cold spot. Conduction is gonna steal your warmth over a period of time, in this instance four hours. I’m new to your channel so not sure when you plan to get on trail, but you might give some thought to swapping out your pad. Looking forward to future reviews and your successful thru-hike. Cheers, Scars.

Good to find out now rather than on the trail what the temp edges of your gear is. Sounds like a comfort rating of 40F is appropriate for that bag…like the update on Amazon. Once the weather warms a little that will be a good primary bag.

Solved my cold feet with a tip from an old scoutmaster. Wear two layers of socks with a handwarmer between the layers (never put a handwarmer directly in contact with your skin for long periods of time). I have tried this down to about 23 degrees in a 30ish degree bad and had NO problem staying cozy warm.

D Collins says:

Have a wonderful time hick your own hick hope your going with others for safety and just to have fun looking forward to more videos

kostas G says:

I advise you not to use this sleeping bag below *F 35.6. Plus 2 sizes are available so carefully choose yours. I love the two side zipper it has, is unique. Nice vid!

David Berg says:

I have the same bag and agree that it do not perform well down to 30f. With the help of using my down jacket as a blanket inside my sleeping bag I have been comfortable down to around 35f. For the price and weight it is a really good sleeping bag.

bereantrb says:

I just learned about this bag yesterday am encouraged by the good reviews. I need a new sleep system but have to watch my costs. Thanks for the real world review. This looks like a winner.

DragonsTrails says:

I’m curious what performance you would have gotten with your SOL bivy. They are suppose to be pretty bomber. Awesome that you are testing before trusting. Thanks for sharing your findings I also learned of this brand from Darwin.

FreeWilleyMammoth says:

Good review! That may be a good option for my summer bag. Heading out in a few minutes for another test of my gear. Supposed to get down to 17*F tonight! Take care, FWM

Mary & Ed - Peaceful Hikes N.J. says:

Love your videos so far, looking forward to more. The bag may be warm enough but your sleeping pad is not rated for freezing temps. You may need a thicker pad or an inflatable with a higher R factor for the cold months.

Phil among the hills says:

I just did a test in my backyard over the weekend testing my 20 degree quilt at 20 degrees and had to wear heavy clothes including a winter coat hood to get by.

Paul D. Green says:

I hope you don’t mind an old redneck from Georgia following your journey. Good luck and thank you for sharing!

dan man says:

Thanks for the review! Which Aegismax sleeping bag is this? Is it the Aegismax Mini, or the Aegismax M2, or the M3? Thanks

Aaron Silver says:

I got one of these bags. Good for summers here in Canada. Thanks for the test. They do make 2 lengths:185cm long & 200cm long

That Larry Guy says:

Thanks for the great review. I’ve been looking at that brand of bags. Would work for most of my North Florida winter weather.

As others have said, more layers will keep you warmer. One of my lightest pieces of gear is a pair of silk hose. Weigh almost nothing, but really add a layer of warmth. We have had some cold nights so far this winter, and the silk hose when worn under wool thermals has kept me toasty is a very old EMS down bag. All next week our lows will be in the 20’s, so I hope to get out and see just how good my system does work.

I’m really enjoying the videos. Keep them coming.

bereantrb says:

Also, another reviewer had this bag out at 36F wearing base layer & sweater and said she was very cold. She later washed the bag (with Nikwax Down wash) and found it greatly improved the loft. She then took the bag out in 31F again wearing base layer & sweater and said she was “toasty.” She strongly recommended washing the bag to get the maximum insulation out of it.

STeVe PNW says:

I start off cold when I crawl under my quilt and warm up over a couple hours and then wake up very toasty. One problem I don’t hear being talked about is having to warm of a bag. I can generally add clothing as needed if a quilt or bag isn’t warm enough but when the quilt or bag is to warm but I would be cold without one, that is not fun.

Good call and the water resistant down.

I look forward to watching your videos when I am in town. My playground is the North Cascades and the Olympics in Washington.

Be Way Happy,

Kenkeepssteppin says:

You should of used your S.o.l. Bivy. They are a amazing piece of gear that more people should carry. I carry the S.o.l. Poncho that I modified to cover myself when sleeping on very cold nights. Good luck and keep steppin

Dylan Thompson says:

I have that bag so I already knew you were gonna be cold in this test haha. I have found that it’s fairly comfortable until around 50, maybe 55, anything below that will require some warm undergarments or just a warmer bag. However, definitely the best summer bag money can buy. I’m going to be doing the same as you and ship out the Aegismax once the trail warms up. Until then I’ll have a 0-15 degree down bag; still shopping around for the right bag.

Steve Johnson says:

Good review, hope it warms up, though.
Could you speak up a bit. I listen to it on speaker phone and it’s just to low to hear.

Jas Holden says:

It’s hard to tell what bag this is since so little of the actual sleeping bag is shown. I think it must be the original green “mini” bag that came out about 3 years ago.

I own the original “mini”, regular size, the M2 lengthened and 2 of the M3, one regular and one lengthened.

In my opinion the “mini” is comfortable down to 50F, the M2 down to 40F and the M3 down to 20F.

Temp ratings require a sleep pad with a suitable R value, a tent or tarp as a wind break and long johns.

The M3 is cut very slender and won’t fit heavy set people. Anyone over 5’9″ should get the lenthened bags. The lengthened bags are both longer and wider than the regular bags.

Here is a link to AliExpress. Scroll down to look at the M2 and M3 bags. The “mini” is like the M2 but it has 230 grams of goose down in it and weighs a little less than one lb. The M2 lengthened has 420 grams of down and weighs 1.5 lb and the M3 lengthened has 550 grams of 800 fill power down in it and weighs 2.2 lb..

Stan the Man Hikes says:

What date are you leaving on your hike?

Jim Joyce says:

Best thing to happen to sleeping bags ever is EN rating. There are typically three values supplied: Lower Limit (think men), Comfort Rating (think women, or cold sleepers) and extreme (the point in which hypothermia is a risk). Generally, the Lower Limit is the advertised rating. But in the past, it was a crapshoot.
I’m really impressed with the magma, comfort rated at 17F, yet weighing just over two pounds. The Amazon bag will work well in situations where the magma would be a sweat festival (or maybe you lay on the bag instead of in it). Sounds like a decent summer bag.
But if you’re planning to start early, the z-rest (r value of 2.6) might not be quite enough. My standard cold weather setup is a small ridgerest under a regular Prolite ( I can sub in a really old standard thermarest if I need to). I do carry a NeoAir Xlite when it is warm. Perhaps you could consider a smaller closed cell pad underneath and send it home in late spring. Just a thought.

Herbert Cornell says:

The adage I have always heard is that the temperature rating is closer to a “survive-ability” rating and that you should add ten degrees to the number for the comfort level. So a 32 degree bag will be more comfortable at 42 degrees but will keep you alive, albeit chilled, at 32 degrees.

Zain Najeeb says:

I am thinking of buying a sleeping bag and I am on a budget. I have two options: Aegismax U, or Aegismax G. I can’t make a decision as which one be a better option. The area where I will be backpacking has temperature reading of about -23F to 32F.

dakotaescher1 says:

30 degrees means it will keep you alive. It is not intended to be the temperature you will be comfortable. Use your 17 degree (15/20) and you will be toasty comfortable warm. Cheap is just that, cheap. Looking forward to following your journey.

The Hiking Sailor on the AT 2018 says:

Don’t forget, when you start getting cold, put more layers on. Still cold, another layer. This is a cold fall and spring hiking tactic that I used in my cold fall spring sleeping system.

2 months ago, for my AT test of my gear during my 35 day hike on the IAT Quebec Section, I was sleeping on top of a 5000 plus foot mountain and it wasn’t freezing but very close. I was using a 40 degree sleeping quilt bag and yes I was cold, but with my liner, puffer, thicker then normal rain jacket, I was comfortable. Plus my sleeping pad and foam padding gave me even more warmth.

In another month I will do another sleep test in minus 39 cel weather with my -1 cel dri down 800 fill sleeping bag.

Please acknowledge.

Frank Fowlkes says:

As Karl said below the Costco down throw would help. I have the same sleeping bag and use the Costco throw as a liner if needed. It will take the bag limit down around 10 degrees. Just fold the throw in half and sew the bottom  together along with about 1/3 of the length and use it as a liner. It’s very light weight and will only add 1 lb to your total weight. It only cost about $20.You can actually use as a sleeping bag during the warmer months. Good luck on your thru hike!

Karel Blankenfeldt says:

The bag is sewn-through, so you have heat loss at those seams. I have the quilt style of that AEGISMAX and same thing. I have a friend that makes down sleeping bags and jackets and had her reshape one of those ultralight Costco down throws so I could tie it in to push the temp rating lower. Those bags are super compact and weight about 1-lb. Hope it’s enough for your trip.

Smoky Mountain Angel says:

Thank you so much for the review. I was seriously just going to order this and instead went back to YouTube and found your channel. I get very cold, so I will be getting at least a 15-20 degree bag. It might be better for summer for me, ha ha.

Alan Taylor says:

not sure when you are starting but i started on 3-12-17 and at Gooch shelter it got down to 8 degrees just be prepared

William Burton says:

I think most body heat is lost through contact with the ground.When its freezing I put my foam thermal rest sleeping pad on top of my inflatable sleeping pad. That keeps me super warm:).

Pando says:

My favorite part of this video is the whispering to not disturb somebody else in the house lol. Good luck on your thru-hike.
