WeatherTec™ 3000/4000 - waterproof systemA tent’s waterproof properties are measured using a rating called its hydrostatic head. If a tent has a hydrostatic head of 3000/4000mm*, it can hold a 3/4 metre* column of water on its surface before any leaks through.
The Ministry of Defence UK classifies a hydrostatic head of 800mm as waterproof.
Coleman® uses polyethylene (PE) groundsheets which are relatively heavy but provide guaranteed water protection. PE groundsheets are ideal for family and active tents where a very light weight and small pack size are not essential.
