Breathe Easy: Why a Breathable Cover Beats a Tarp Every Time

When you’re storing your camper, trailer, or boat for the season, it’s tempting to toss on a tarp and call it a day. Tarps are quick. They’re cheap. They’re everywhere.

But tarps also do one thing really, really well: They trap moisture.

And when moisture gets trapped… that’s when the mildew party starts.

Tarps = Moisture Trap

Tarps don’t allow airflow. Moisture gets in (humidity, frost, condensation), but it has no way to escape.

Within weeks, you can end up with:

Mildew
Musty odors
Soft spots on wood
Staining on canvas or cushions

Nobody wants to open their camper in spring and smell wet basement.

Breathable Covers = No Mildew Surprises

Breathable covers are designed for outdoor storage and seasonal protection. They:

Allow air circulation
Release trapped moisture
Reduce condensation
Prevent mildew and mold buildup

Think of it like putting your camper to bed in a cozy blanket — not wrapping it in cling wrap.

Why These Covers Matter

Winter storage requires durability, proper ventilation, and materials that resist snow, ice, and moisture.
Many owners report that non-breathable tarps cause problems like mold and mildew from trapped moisture.
Proper fit, good venting, and tie-down systems matter just as much as material.

Quick Tip List

Measure your trailer/boat first (length + height including any ladders).
Choose a cover that has breathable sides, durable roof, adequate tie-down systems.
Make sure the cover does not touch the ground (remind them for your lot).
Secure it properly—loose covers can create wind damage or flap and scratch surfaces.
For winter storage in Michigan/your region, consider the premium layers if you expect heavy snow or ice.

Very Important: Secure Your Cover

To protect your equipment and keep the lot safe:

Covers must be properly secured
No loose straps or ropes
Covers and tarps may NOT hang on the ground

Short version: If it blows in the wind, it needs to be tied down.
