Outwell Vermont 6P Tent (2019)

Berth – This shows the number of people that the tent can sleep within the inner tents of a model of tent, in line with the industry standard. Normal procedure is to look for a slightly larger tent, for example, a family of four usually purchase a five or six berth tent, to give added room and comfort.

Hydrostatic Head (Tents) – a waterproof rating for technical fabrics measured in mm. The higher the rating the more waterproof the fabric is. A rating of 1500mm is deemed waterproof, but on a tent, look for a rating of 3000 or higher. Measured by the height of water column a fabric weave can take before it begins to “sweat”. “Polycotton” tents will not have a Hydrostatic Head level, as they are not treated for waterproofing.

Polyester – a synthetic fibre, made from polymer units to create a textile fabric. Polyester is the most popular fabric for tent manufacturing, as it is durable, reliable and lighter in weight. Polyester does not breathe though, which creates more condensation.

Polycotton - a blend of polyester and cotton, primarily cotton (usually around 65% cotton / 35% polyester split). Polycotton is a more natural fabric for camping, as it is breathable, far more durable material, reducing the effects of condensation. Offers greater versatility in hot and cold climates.

Ripstop Nylon – a durable material used in tents which is strong and repairable due to its Ripstop properties.

Fire Retardant – all modern tent fabrics are fire-retardant under EN5912 European Safety Laws. Caution with fire must always be used, as flame retardant fabrics, will still catch fire given the right circumstances.

Double Skin Tent – A tent with an inner bedroom and a flysheet, most family tents are designed as a “Double Skin tent”, as it makes the tent more comfortable, and lessens the effects of condensation.

Most tent structure are either Airbeam or Poled in design, both have advantages and disadvantages. Air tents are quicker to pitch, but more expensive when compared to traditional pole style tents. Some tents are hybrids, and combine poles and air technologies.
