Frequently Asked Questions
Are these tarps suitable for backpacking?
They can be, but suitability depends on your tolerance for weight. 5.5–6 mil tarps (like the RAINDEWAY 5.5 mil) pack lighter and are better for shorter or ultralight trips; 8 mil tarps offer more durability but are bulkier. Consider tie-down technique and protective corner wraps to avoid stress damage.
What does '8 mil' or '5.5 mil' mean?
'Mil' measures material thickness (one mil = 0.001 inches). Higher mil equals thicker, usually more durable material. 8 mil is thicker and tougher than 5.5 mil, but heavier to carry.
How should I care for and store a polyethylene tarp?
Clean off dirt and moisture before storing to avoid mildew; dry completely if wet. Fold or roll loosely to prevent creases and store in a cool, dry place out of direct sunlight to slow UV degradation. Avoid prolonged contact with sharp objects or abrasive surfaces.
