Lim Mei Er –
What I like about this product is its bright blue color, but what I really love is its ultra-heavy-duty tarpaulin material. It’s like a fortress for my valuables. However, the only reason I’m giving it 4.5 stars instead of 5 is because the material does scratch quite easily, so it requires some extra care.

I just wish it came in more colors or had multiple compartments to organize gear
Rachel Wong –
Is the Mares T25 Dry Bag suitable for sailing in rough seas?
Imran Hanafiah –
Dear Rachel, thank you for your question. The Mares T25 Dry Bag is designed to provide a waterproof seal and is made from ultra-heavy-duty Tarpaulin with PVC reinforcements and thermo-welded stitching. While it’s suitable for general water activities like kayaking or snorkeling, it may not be the best choice for sailing in rough seas. Its 25-litre capacity and closure system are great for storing gear, but it may not provide the level of protection you’d need for sailing in harsh conditions. For such activities, we’d recommend checking out our more heavy-duty dry bags. If you have any other questions or concerns, feel free to ask! Best regards, Team.

I’m not sure, does it have a built-in clip to attach to my life jacket?
Junhao Lo –
Hello Amanda, thank you for reaching out to us about the Mares T25 Dry Bag. The answer to your question is that it doesn’t have a built-in clip to attach it to your life jacket directly. However, you can use a carabiner or a clip that can be attached to the bag’s top loop to securely fasten it to your life jacket. We recommend using a carabiner that is compatible with the size of your life jacket clip.

I’m not sure what’s going on with this product, but the bright blue color seems to be attracting a lot of bees. Seriously, it’s like it’s a bee magnet!

Has anyone ever noticed whether the Mares T25 Dry Bag’s clip is removable or not?
Junhao Lo –
The Mares T25 Dry Bag’s clip is designed to be secure and reliable, but I can confirm that it is not removable. This is intended to ensure the waterproof seal is maintained.

The Mares T25 Dry Bag has been a game-changer for me on my sailing trips. Its 25-liter capacity is perfect for storing essentials like first-aid kits, flashlights, and emergency beacons. The ultra-heavy-duty tarpaulin material is incredibly durable and has withstood rough handling. What’s more impressive is that the product’s waterproof seal has kept everything dry even in harsh sea conditions. The bright blue color is a nice touch, too.

The T25 dry bag is great for casual water activities, but I’m not sure if it’s suitable for more extreme conditions. I wish they had a more detailed description of its abilities.
