Weathering Your Tent
Weathering...Polyester tents can suffer from excessive amounts of condensation and this can sometimes be reduced by opening and using the vents in the tent and keeping wet clothing etc out of the tent, some polyester tents do need to be weathered as some manufacturers use a mixed fibre thread on the seams of their tents and awnings. Customers may need to use some seam sealant or waterproofing spray on polyester tents as it is impossible to make every seam 100% fully waterproof. Poly cotton tents can also suffer from a build up of condensation but it will be far less than a tent made of a polyester fabric.
Poly cotton tents do need to be weathered, this is a cycle of soaking the tent and allowing it to fully dry out, this allows the fibres to swell and knit together, seams need this cycle even more than the main tent fabric. This cycle normally only need to be done once but depending on the weather this may take a couple of cycles. If a poly cotton tent is used for the first time in rain and has not been pre weathered and the rain is medium to heavy or prolonged expect a poly cotton tent to allow water through the fabric, a mist may form on the inside of the tent, once the weathering cycle has been completed a good poly cotton tent will be highly water resistant but please note, no tent can be made to be 100% fully waterproof, this is the nature of camping. Seams are more prone to water ingress and may need a spay of a tent waterproofing (we prefer the Storm brand) to make the seams more water resistant, do not be concerned as this is typical. Ideally the weathering process should be done before the tent is used for a holiday. Poly cotton tents will never be as waterproof as a polyester tent but the advantages of the more comfortable living environment far outweigh the small amount of water that may enter the tent.

"When the Smart Air Poles (tubes) are inflated they can ‘stretch’ the needle holes making them much more vulnerable to water ingress. To alleviate this potential issue we recommend that, prior to use in the rain, all the Air Pole seams are sprayed on the outside of the tent with Outwell Waterguard, or a propriety make of waterproof spray suitable for polycotton fabrics – this can be done at the campsite when you first arrive if need be. This treatment is fully advisable for all Outwell polycotton Smart Air Tents and will not affect the weathering process or the waterproof and breathable properties of the fabric when in use."
