I was in the Belfast branch of Decathlon and they have the Quecha T 6.3 XL B Family tent on offer. Details below :
Living areaHuge (10.5 m² / 2.10 m high), plenty of room for 6 people, without forgetting the storage areas to either side of the rooms -- Permanent canopy = no need to pitch and fold away several times a day (rain, lack of rain...), front that can be partially or fully opened, even when it rains -- Rising groundsheet to avoid water trickling in from outside. This groundsheet can be removed.
Room3 superior rooms that are 1.60 m in width and 2.30 m in length (without the added headroom) -- Breathable polyester -- 8 internal pockets + 4 external pockets for each room.
WaterproofingAs with all Quechua tents, a lot of work is put in to ensuring they are watertight, through laboratory testing (an ENTIRE TENT is put through 200 litres/hr/sq m!) and field testing -- PU-coated polyester flysheet -- Seams are sealed with thermo-bonded tape -- 140 g/sq m polypropylene groundsheet.
Ventilation and condensation controlLarge air vent at the top -- An air vent for each room -- Gap between the ground and the flysheet - Can open the top of the facade even when it's raining.
PolesStructure that is very stable and sturdy: 12.7 mm diameter glass fibre poles for the living area (11 mm for the room structure). -- All the fibre poles are quality tested twice to ensure the best possible resistance to breaking.
PegsExcellent resistance to twisting (6 mm diameter steel).
PitchingStandard, starting with the dome-shaped living area -- Pitching video available on http://www.quechua.com.
Warranty and After-sales serviceGuaranteed for 2 years under normal conditions of use -- Every Decathlon store will carry out the after-sales servicing of your tent by replacing faulty parts under guarantee or those you have damaged (for payment) on the flysheet, inner tent, pole rings or carry bag. When a replacement cannot be done, a repair will be suggested.
I'm not sure if it's nationwide, but the Belfast store has dozens of them instock, amazing tent for that price. Call your store beforehand.
