It's all about liveable space with the Trail Ridge with near vertical walls resulting in increased chill-out space and dual-doors enabling entry and exiting without stepping on your backpacking partners. On clear summer nights, you can use it without the rain fly and gaze at the stars thanks to the fly being mainly mesh.
Once a suitable pitch is found, simply assemble the poles in the form of an 'X' on top of the tent, stake out the corners of the tent and insert the poles into grommets on all four corners forming a frame (Step 1). Attach the body clip at the centre of the tent and lay ridge pole over tent and attach ball cap clip to each end (Step 2). Then work your way around the tent attaching all pole clips on tent body to the poles (Step 3). Then you can drape the rain fly over tent body (Step 4), fixing it with rain fly buckles and the ridge pole ball cap clip. Stake out vestibules and add guy lines and it's ready for use.
