    Comments about Flash 4 Tent - 4 Person, 3 Season:

    First of all don't shoot me for calling this a backpacking tent, I KNOW it's heavy, but hear me out.

    My family has had a Sierra Designs Sirius 3 for many years and we are completely in love with the tent. Its hybrid design, lightweight materials, durability and extreme ease of use has made us Sierra Designs fans. As our family is growing, however, a three man tent is not nearly big enough for us all and I started looking for something larger... Reviews online said that if you like the features of your other SD tent, that you should purchase another one as they've just gotten better.

    We have not been disappointed in this new tent, as a 4-man it is a pretty heavy and large tent to haul around backpacking, but it is CERTAINLY doable. Splitting the poles, tent and fly between packs really distributes the weight and makes backcountry fun available to our young family.

    The poles for this tent are very well made and the color coding makes set up a breeze, we have found that the bulk of poles needed for this tent is a bit ungainly, but certainly manageable.

    The tent itself does not separate from the fly, which may make it harder to clean, but does mean that you can set up in the rain without exposing the inside of your tent to water. You can even put your gear inside the tent to stay dry (tarp style) while you attach the poles on the outside.

    You should note that this tent is not quite as freestanding as other SD tents, due to the centerline pole design the corners of the tent are not held very taut when not staked. We've found that staking our tents in rocky terrain can be difficult and freestanding tents are handy, the floor will bunch on you in this tent if it is not properly staked.

    Generally we are thrilled with the design of this tent: generous vestibules that seal out rain, lots of venting for hot nights with the ability to button down for chilly ones, a simple yet effective design and little to no condensation make this yet another favorite.
