Non-waterproof

Describing something that is not resistant to water penetration; lacking the ability to prevent water from passing through or damaging it. This term signifies a vulnerability to water, meaning the item or material will likely be damaged, rendered ineffective, or otherwise compromised when exposed to moisture. This is a crucial characteristic to consider for items intended for outdoor use, protection from rain, or situations where contact with water is likely. The degree of resistance can vary from slight to complete impermeability, hence 'non-waterproof' implies a complete lack of water resistance.

Non-waterproof meaning with examples

• My antique leather journal is non-waterproof. A single drop of rain could ruin the delicate pages. I must always keep it safely tucked away when I venture outdoors, or carry a protective waterproof bag with me to shield it from any unexpected downpours. It requires a great amount of care compared to my waterproof, synthetic, modern day notebook.
• The tent we brought on our camping trip was advertised as non-waterproof. Consequently, we had to carefully select our campsite to ensure it wouldn't flood during the night. We also packed extra tarps to attempt a degree of protection if we encountered wet weather. Unfortunately, this made the trip cumbersome and involved a constant worry about keeping all our belongings dry.
• The cheap, non-waterproof phone case I bought offered inadequate protection when I accidentally dropped my phone in a puddle. Water seeped in immediately, resulting in irreversible damage to the phone. Now I understand that spending extra for a waterproof phone case offers significant advantages and peace of mind in case of accidental submersion.
• The paper labels on the food products are non-waterproof, so when the condensation gathers on them in the refrigerator the ink runs and the label tears. This makes them difficult to read and potentially leads to errors. The food product manufacturers have invested in waterproof labels which makes the information on their product clearly visible in adverse situations.
