Does it insulate the water at all, and be assured that when hiking in the hot sun that I wont be coming to nasty warm water?

Maybe a little, but if you leave it in the sun the water will definitely get warm. It's thin and meant to be very lightweight, so I wouldn't say insulation is it's primary purpose.

I tie mine to my roof rack and use it as a solar shower. It heats up very nicely! You would have to put ice in it and insulate it well in your pack to keep it cold.

The bag is made of a rubberized material, so there would be some insulating qualities to it. But it's black exterior will naturally absorb heat better, allowing for a nice little warm shower at the end of the day.

This is off point, but I will say it's a great river bag. Tie a strap to it and dunk it in the river periodically, and it'll keep the water cool even on a desert river trip. It's almost like one of those old evaporative canteens.Hiking, though, and sitting in the sun, it's going to get warm.

I'm afraid not, if you leave it under the hot sun, most likely it'll get warm. Not forgetting it's black in color and it's made of plastic material in n out. If you're using it as a water bag placing inside ya bag pack, what you can do is fill 1/3 or even half of it with ice cubes then fill it up with water. Wrap it up with a towel and place it in ya bag. It'll keep you cool and give you ice cool water to drink. If you had a base camp, I suggest you hang it under a tree or any place with shade. Hope this answer ya question. Happy hiking

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 didn't notice any problem but I do not know if it actually made my pool warmer. I'm trying now to save for a solar cover & will not buy this anymore

It is not 'lined' but does offer some degree of warmth. I bought mine for use in Hawaii where the water can be a bit cool if you in it for a while. I was definitely comfortable and it kept me from getting sunburned while snorkeling. Not as warm as a wet suit but way less expensive and more comfortable. I would recommend getting a hood for additional warmth and sun protection.

no your skin will be wet but it will keep you warmer then if you were just wearing a bathing suit.

It's not meant to keep your water warm, only heat it up. If you want it to stay warm after you'll need a thermos.

It doesn't really act like a wetsuit. It is comfortable, light-weight & fast drying. I wear it around walking, hiking, etc jump in the water & leave it on to dry. I am very sensitive to the sun, so that's why I wear it. I usually swim in warmer waters. In cold water, I'd wear a wetsuit.

No, it's too thin and the interior is coated. It would probably leach into your water, especially once it was heated.

It's has a waterproof lining. Don't know what it's made if but it's like plastic but not hot

This is not thermal, it is intended to protect from dangerous UVF sun exposure. Add thermal to your (swim) garment search and that will keep you warm.

This one is not insulated - the insulated one is "Podium Chill". It does not leak ever! Even if it is in the open position it doesn't leak into backpacks -that's why I think its worth the money...

No, it doesn't warm the water but room temperature water is quite comfortable, even refreshing.

It doesn't, but the pack material and construction make it water resistant.

Both...it absorbs water quickley and in summer actually keeps you cool as the water evaporates

It doesn't actually cool the water, it just circulates the water around. But the mere motion of the water being moved around should keep it cooler than a sitting pool of water.

It keeps the water warm for a long time....I was amazed how well insulated it is. Perhaps 4-5 hrs?

The lid seems to keep water out where I keep mine, it might be slightly sheltered under trees, but I havehad no problem.

I have never seen it get hot. It may get warm, but it is reflective silver, and attached to a metal hose bib with water in it.
