Tents

How waterproof are JACK WOLFSKIN tents?

All JACK WOLFSKIN tents are completely waterproof in the critical areas (groundsheet, flysheet). This waterproofing is provided by the waterproof coating on the fabric as well as waterproof coverings on the zips, etc.

A material is waterproof according to the DIN standard if it can permanently withstand a water column of at least 1,500 mm. The tent materials we use far exceed these values. The seams are always potentially permeable, as the needle holes also affect the coating. All the seams on JACK WOLFSKIN tents are therefore sealed with a special tape seal. If the seal deteriorates through use, you can use the seam sealant supplied with every tent. The paste should be applied to all seams that come in direct contact with rain (when pitched) and be left to dry for approx. 10 hours. This will eventually form a flexible and waterproof film.

Tent materials with a silicone coating will not adhere to conventional seam tape seals. Therefore, silicone-coated materials are manufactured with a special thread which swells up when wet, making the stitching almost entirely waterproof. However, we do recommend applying the silicone seam sealant provided both inside and out to those seams particularly where several layers of material or tensioning loops are integrated into the seam.
