Looking for a cold pack to go around the waist to keep cool on hot days (heat makes MS worse). Would this stay cool long enough to use for this use?

Not likely I would say it stays cold anywhere from 20-30 min tops then you need to throw it back in the freezer to cool it back down, which also takes about 30 min to make it cold again.

I don't think so. I lay on it for about half an hour at one time. BY the end of the time. The pack is fairly heavy too. I don't know a way to secure to your body. Hope this helps.

I'm not convinced any reusable cold pack would suffice since the active body warms them sorta fast. But this one's higher density and mass might go the diatance. It is heavy though.

It stays cold for a couple hours but it's so extremely cold that I wouldn't think it would be comfortable to wear for that long.

This size will stay warm for about 15 minutes when insulated against your skin. Larger packs will stay warmer for longer periods of time.

It does not insulate at all, as is the case with most other hydration bladders. On a hot day here in New Mexico when I go hiking I will fill up my 4L bag half with cold water and half with ice and it seems to keep cool enough for me throughout an 8 or 9 hour hike. My backpack has a bladder sleeve, and I think that and the rest of the stuff I pack inside the backpack help to insulate it somewhat. The opening of the MSR bladder is wide enough to fit large ice cubes. Also, keep in mind that you have to order the bladder and the hose seperately. It is pricier than most other bladders, but the sturdiness and simplicity of this system are worth it. It does not insulate at all, as is the case with most other hydration bladders.

I think in the description it says for either , it has a lot of adjustments so it can fit a variety of different body types and is light enough that I believe it would work well for you . The only thing I think you would have to think about is what size pack do you want or need , this pack is big enough to easily stay out 2 or 3 days according to what you take .

It does get warm, but I like to think of it as 'whittling my waistline'! :)

I have never used it for keeping something warm, but I imagine it will work for that too. I know that it is the best cooler I have ever owned for keeping things cold over an extended period of time.

It is warm. I do like the sweatband as the rim of the cap but that might not be enough for hot tems.

I don't know why you couldn't lie on it or put it against your back while sitting. It would feel lumpy lying down on it, I should think. Usually I have it around my neck and on my shoulders either while standing or sitting. You can also put it around your waist with the heat on your back. You would hold on to the two handles to keep it snug around your low back. Hope this helps. I love this pack.

Temp wise, it doesn't hold a ton of heat like I have seen complaints with other brands. You should look into ones with the cooling gel if you like being cold.

I've never tested it that way. In a room of normal temp I would say yeah it will stay cold. It depends on how hot it is outside. Keep in mind you only have the ice packs in the main food compartment, so everything in the side cups will warm faster.

Yes! I use it for my kids' lunch and the pack is still cold when it comes home in the afternoon. Works great!

I didn't find the bag to be too hot. We overnighted at just above an 8,500ft summit in Southern California with windy conditions and it kept me warm. It's light weight material allows for good night sleep in most conditions. It should be comfortable to use in both situations.

Hi Dawn. So the short answer is I don't know. But I wouldn't expect it to have any magical powers in resisting freezing. That same air-scape suspension that allows your back to stay cool in the summer would keep your body heat from warming the reservoir in the winter. Though, if your back is full, it is the first thing on the back side of that pack. I hope that helps.

I think you'd have to ask the manufacterer how the pad stays cool. I just know it's supposed stay cool for hours and it does stay cool. It's helped me with my hot flashes. It's so cold that I couldn't leave it under my pillow case so I put it on my neck, stomach, legs. You can also sit on it.

Absolutely. I took it backpacking last week and it was 32 degrees in the morning. The compression sack it comes with is fine. The straps look like they will tear under pressure at some point but so far so good.

There are two cold sides--cloth side is less, but both get and stay very cold. I bit bulky but worth it for sure.

According to the instructions, the pad can be used as a cold pack. However, I have only used it for heat.
