The Big Agnes Black Flying Diamond 6 is a solid family tent with a great combination of space, durability and ease of use. Campers would not suggest considering this a true four-season tent due to some zipper and venting issues, but for most weather the tent performs very well. Four- and eight-person models are also available; the only difference in the models is size.
Spacious. Campers praise the spacious feel of the Big Agnes Flying Diamond 6 -- and other reviewers say the same about the other sizes of the tent. Reviewers like the partition between rooms and extra tall head clearance. The shape of the six- and eight-person models provides a wide area for sleeping. In one user's video review of the eight-person tent, the camper's wife (5 feet, 8 inches) was able to lie down and raise her arms above her head without reaching the walls. However, campers still recommend buying two camper sizes up. For example, if you wish to sleep six, buy the eight-person version.
The tent features many guyline anchors in order to create a taut windproof surface. Still, reviews vary concerning wind resistance. While many claim it stood up to the worst gusting rainstorms they ever experienced, others report collapsing problems, especially with the four-person tents. "Didn't do as well in the wind as I was hoping for," explains one disappointed Backcountry.com reviewer.
Several users had issues with the zipper getting stuck in the fly. The fly covers the tent entirely and fits snug. It features side air vents, which are held open by small "sticks." Customers disagreed concerning ventilation. While most found it adequate, a few complained it was so poor that they switched tents.
Large vestibule. The Big Agnes Flying Diamond 6 is not capable of fast-pitching, but users attest setup is easy enough after thoroughly reading the instructions, which are attached to the storage bag. At least one owner says setup took less than 15 minutes with two people. Inside the tent, campers found the hanging mesh pockets handy.
The Flying Diamond fly cover can be staked out with trekking poles to create a canopy-style vestibule. It can also be guylined to create a shaded vestibule.
Zipper downfall. The only recurring complaint concerning the durability of the Big Agnes Flying Diamond 6 is a poor zipper design. The zipper becomes caught in the overlapping fly material, campers report. Plus, a few user reviewers experienced broken zippers. "Nothing ruins a tent like bad zippers," says one camper on Backcountry.com. Another claims the zippers have a hard time getting around the bottom corner, and a few more had leaking through the zippers. Big Agnes provides a lifetime warranty, but none of the campers who report broken zippers mention attempts to redeem it.

Review: Big Agnes Flying Diamond 8 Review, Devin Chance, Sept. 16, 2012
Review Credibility: Very Good Ten gear testers at Backpacker.com are given credit for testing the Flying Diamond 6, but the review only features the experience from one who, thanks to the weatherproof qualities of the tent, says an otherwise miserable camping trip was a memorable trip because she, her husband, two daughters and dog were all comfortable and dry in extremely rainy conditions. The review is older; it was part of the 2009 Fall Gear Guide, but the tent has not changed appreciably since then.

Review Credibility: Fair About 10 campers sound off on the performance of the Flying Diamond 6 on REI.com, awarding the tent a perfect score of 5 stars out of 5. Comments from reviewers are lengthy in general and provide great insight from hands-on experience. Unfortunately, one reviewer brings the average rating for the four-person down drastically by giving it only 2 stars because it was the "wrong tent for [his] needs." This is a user error, not an indication of the tent's quality; he even went on to praise the build of the tent.
