Does this protect from moisture? Some of my credit card gets damaged every 1-2 years of use due to too much of moisture/sweat.

It is lined on the inside with a metallic something, but I wouldn't say it's waterproof.

These card holders are a simple envelope. They appear to be made of tyvek with a foil lining. Tyvek does not absorb moisture nor does foil. So they would most likely protect from perspiration. However, they do not seal and are open to any moisture that might collect around the opening of the envelope. I don't know how well they hold up to normal wear as I have only had them for two and a half months now.

No, it doesn't. It hasn't harmed any of my cards. I have had several cards in the pockets since I got it and they are fine.

It's not designed for rain or moisture protection. It's designed for drop and ding protection. It likely does add a small amount of waterproofing due to the rubber port and jack protectors. If you plan to spend hours in the rain or minutes in a flash flood, I suspect this case would not be sufficient.

The arm bad is of a heavy nylon material, i suspect it will cause more sweat! I purchased this case for just this, yes it protects the SD Card opening. For the price, and the case it is a reasonable purchase.

Not at all. If you tend to dry you can put moisture on over it. You only have to wait 15 minutes or so. They sell this product in my dermatologist office. I have been using it for a few years.

I have not had that problem, and I tend to sweat quite a bit (literally dripping after a couple of runs while visiting FL last month). The band's material is pretty substantial, so I don't think moisture can get through it from behind your phone. Sweat could potentially come through the opening at the top, but I still think it's unlikely.

We have not had any problems like this (although we open our case fairly often...), but it probably wouldn't be a bad idea to throw in a couple of desiccant packets to absorb any moisture and protect your contents, just to be on the safe side.

I keep mine full & in my pocket. There is a faint line on the screen protector from where the stitching of the see-thru pocket rubs, but no damage. I'm sure if I kept fewer cards in it and/or didn't keep it in my pocket there would be no problem at all, but it doesn't bother me enough to change my habits.

Here in Houston, TX it's very muggy throughout the summer, and the high humidity persists pretty much year-round. So far we've seen no condensation on the inside, and the material is pretty stout. I'd think if you move it around from place to place, damage will occur from abrasion, but if it just sits there it seems to hold up fine.

Yes, the phone does get damp after a lot of sweating. The inside plastic actually had sweat beads on it. It is hard enough to get the phone in and out of the armband. I am sure that having anything on it will make it more difficult. I hope that someday, the companies that make these phone protective cases, the kind with belt clips, will also make a clip or holder for running as well. Seems to make the most sense. I hate taking my phone out of my otterbox just to put it in the running armband.

Sukhraj,I poured some water on my backpack and it did run off. When I put my hand on the inside, I could not feel any wetness. The small phone/ipad pocket on the top would not be water-proof, but its is sealed-off from the other compartments. The fabric is pretty tight, so spraying a water-proofing agent on it would certainly help.

No- it doesn't leave any moisture on the area around it. Mine sits on a wooden nightstand and has never left any marks.

I typically use these in storage of food items so once I open the item back up I assume it is going to start absorbing ambient moisture, but haven't noticed them doing so quicker than I have used the product. You may want to check you re-opened items monthly for any sign of moisture, ie clumping to know when to toss one out and replace or add a new one. They put these things inside purses and stuff in wharehouses for years and they seem to still work, maybe check the manufacturers website, they may have statistics.

Hi, It will keep everything locked up, but it will not prevent moisture. Air will come in from the sides.

Its not an air tight seal. Im not sure if there is any type of box that is like that. If you are that concerned about humidity, double sleave your cards and you should be fine.

Hi Judith; I bought two of these safes and am pleased with them. I haven't had a problem with moisture. The instructions do say to leave the door open for a while every few weeks. Hope this helps.

It does not allow moisture to seep through the bottom. I have not had a problem with moisture seeping through it yet.
