Within the Arco XT 3P, the large inner room provides ample sleeping space with enough room for trekking gear, packs and other vital outdoor equipment, all of which can easily be ventilated in the ridge. The design of the Arco XT 3P is perfect for trekking tours, offering the best possible space utilisation with low weight and most importantly, quick setup. When adverse weather arrives, Vaude have included stormcord collector guylines to support the frame and fabric with a waterproof taped entrance zip to seal out the last remaining molecules of water. After pitching quickly, the Arco XT 3P is strong enough to take on a storm face on and is ideal for treks in milder climates. The VAUDE label "PVC-free" means that this product is manufactured 100% free of PVC (polyvinyl choride). PVC largely contains plasticizers (phthalates) that are considered to be harmful to your health.
