For FZY Tents, "Waterproof" implies that all external fabrics are coated with our high-quality coatings, endowing them with perfect waterproof performance. The "mm" rating refers to millimeters, which is a standard unit of measurement for waterproof performance. For instance, if a tent has a waterproof rating of 3000mm, it means that the fabric can withstand a water column pressure of up to 3000 millimeters (approximately 9.85 feet) for more than one minute without any seepage occurring. Such an excellent waterproof grade ensures that even in extreme weather conditions with raging hurricanes and torrential downpours, rainwater cannot penetrate into the tent.

The Letter "D" Represents Denier, a Unit Dedicated to Measuring the Fineness of Fibers, Filaments, and Yarns. The Denier Value Is Closely Associated with the Thickness of the Fibers. A Lower Denier Value Implies That the Fibers Are Lighter and Finer, While a Higher Value Indicates That the Fibers Are Heavier and Coarser.

2. The Letter "T" Stands for the Thread Count, which Specifically Refers to the Combined Number of Warp and Weft Threads in One Square Inch of the Fabric. The Level of the Thread Count Directly Impacts the Tightness of the Fabric's Weave. When The Thread Count Is Low, the Fabric Is Woven Relatively Loosely; Conversely, When the Thread Count Is High, the Fabric Is Woven More Tightly. To a Great Extent, These Two Values Determine the Strength and Texture of the Fabric.

The Formation of Condensed Water Inside the Tent Is Mainly Due to the Large Temperature Difference Between the Inside and Outside, Which Causes Moisture to Accumulate. There Are Several Reasons for This:

1. Weather Factors: High Humidity, Low Temperatures, and Rainy Weather Can Easily Lead to the Formation of Condensed Water.

2. Human Exhalation and Evaporation: Every Night, Through Breathing and Skin Evaporation, Humans Release Moisture, Increasing the Humidity Inside the Tent.

3. Wet Environment: A Wet Ground and Wet Equipment Placed Inside the Tent Are Both Sources of Moisture. To Reduce the Amount of Water Inside the Tent, It Is Necessary to Ensure Good Ventilation in the Tent. You Can Use Mesh Fabrics, Vents, and Open Doors to Enhance Air Circulation. Open at Least Two Vents and Prop up the Rainfly to Reduce the Water Inside the Tent.

A Tent Only Needs to be Cleaned When It Has A Strong Odor or Severe Stains. Over-Cleaning Can Affect The Performance of The Tent.

Here Are The Effective Cleaning Steps:

Light Cleaning: Use A Hose to Rinse Off Any Loose Dirt from The Tent Surface.

Deep Cleaning:
1. Set Up The Tent.
2. Hand Wash With Warm Water, A Sponge, And Mild, Non-Detergent Soap.
3. Avoid Using Harsh Cleaners Like Dish Soap, Laundry Detergent, Bleach, Pre-Soak Liquids, or Stain Removers.

Rinse and Dry:
1. Thoroughly Rinse The Tent to Ensure No Soap Residue Remains.
2. Allow The Tent to Air Dry Naturally, Avoiding Tumble Drying or Direct Sunlight.

Important Reminder: Never Use Dry Cleaning, Machine Washing, or Machine Dying, as These Methods Can Damage The Tent's Waterproof Coating.

Preventing Mold is Key to Extending the Lifespan of Your Tent.

Please Follow These Preventive Measures:

Dry The Tent Immediately: Do Not Store a Wet Tent in Its Carry Bag. Mold Can Begin to Grow Within 24 Hours in Warm, Humid Environments.

Ensure Complete Drying: Make Sure the Tent is Fully Dry Before Storing It. Even if It Looks Dry, It’s Best to Hang It Outdoors or in a Well-ventilated Indoor Area for a Few Days to Ensure Every Part Is Dry. You Can Also Flip the Tent Inside Out to Allow Both the Inside and Outside to Dry.

Avoid Using A Dryer: Never Use a Tumble Dryer. The Hot Air Can Damage the Fabric and the Waterproof Coating of the Tent.

Note: Mold Can Cause Permanent Stains and May Damage the Waterproof Coating, and Such Damage is not Covered Under Warranty.
