By putting an emphasis on strength rather than weight, the engineers at Crux have created a strong, versatile base camp shelter with the X3 Bunker 3 Person, 4 Season Tent. Designed to weather the storm while you wait for the weather to clear for your summit attempt, the X3 Bunker has a double wall construction with a stout 45D ripstop nylon fly treated and a silicone coating rated for up to 7000mm of protection from snow. The inner canopy is composed of a 30D high tenacity nylon for additional protection from the elements. The groundsheet is comprised of a 90 denier PU coated taffeta nylon that is not only water resistant, but will readily resist tearing. Two entry points further increase this tent's versatility, while a large front and shortened rear vestibules provide plenty of space to ready equipment and cook food out of the elements. Five DAC Featherlite NSL poles strike a balance between strength and weight, while two vents at the front of the fly help to promote breathability. Internal storage pockets give you a place to stow small pieces of gear. And with six Dyneema guylines fitted with mini Linelok adjusters, you can sleep easy when things are socked in knowing your tent is secure.
