Choosing the right materials for your tent Choosing the right materials for your tent Choosing a tent can be a challenging business. There are a wide range of materials involved, from the fabric on the outside of your tent to the pegs you use to hold it down. This Data Sheet looks at some of the materials you are likely to encounter when buying a tent. You can find out more about other things to look for in another Data Sheet – Choosing a tent layout . Benefit from expert advice, retail discounts and money off pitch night stays when you join the Club . Tent fabrics Most tents will have two layers – an outer cover known as the flysheet and an inner tent for sleeping. In almost all cases, you won’t have a choice of fabric for the inner tent, so as long as it is breathable (to prevent condensation building up overnight) you should be fine. However, there is a range of materials available for the flysheet. Read on for more details. Polyester Most tents on the market today are made of polyester. This man-made fabric comes in many weights and with a variety of coatings, many of which are given brand names by their respective manufacturers. Polyester has similar properties to nylon (see below), but it does not stretch or shrink as much and by using specialist coatings can be made to be quite UV stable. Higher grade polyester tents may also have a ripstop weave, this is identified by a cross hatching in the weave and inhibit tearing.
