We put these to the test on the Grand and loved them roomy, easy to set up, great views! Straight walls and aggressive arch toward the top give extra room. Two flanking vestibules make easy entry from both sides and lots of storage. Body is freestanding for star filled nights! Floor is 68D nylon with taped seams. Fly is 78D polyester. Comes with gear loft loops and internal storage pockets. The Trail Ridge incorporates a multi-diameter pole configuration that enables the walls to stay steep and aggressively arch toward the top for a much larger livable space. For more space, this tent includes two equal-sized vestibules for plenty of storage. 4 person is 55 sf, 82 x 97 x 59 in weighs 10lb 7oz.
