While there's no tent that works for all purposes in all environments, IMO this is the perfect tent for summer, or year round in Florida. It's a free standing, double wall tent, but the inner tent is 100% noseeum mesh; perfect for stargazing on those still humid nights. The outer fly can be set up to provide ventilation almost all around the perimeter and the top of the door can be left cracked open, in all but driving rain, to create a top vent.
While this is advertised by Big Agnes as a 3 person tent, forget it unless it's one adult and two small kids. However, at this weight, 4 lbs, 2.4 oz including stuff sacks (no stakes), this is a very lightweight 2 person tent that is full featured.
The floor dimensions, as measured by me, are 87" length by 49" wide at rear, 71" wide at middle and 57" wide at front. It is 46" tall. This is a very roomy tent. The vestibule is just big enough for a couple of packs and shoes but tightly. However, with so much room inside, your gear can be brought in with you. The walls on the Seedhouse SL3 are nearly vertical, making that large floor area really usable.
Three stakes will secure this tent but to open up the bottom for ventilation you need 7. The tent has 11 tie-out points in the fly if the weather requires it. It sheds wind well. The inner net tent has 6 additional stake points. The tent comes with 13 aluminum stakes, which I replaced with titanium ones (hopeless gear-head). Again, I never use more than 7 stakes.
I am 6'2" tall and this tent allows me to stretch out with a long size sleeping bag. I can get a pull-over on while sitting up without touching the ceiling. It is luxurious!
Another characteristic of this tent that I like is that it's overall footprint isn't overly large for it's floor area. The measured floor area is 37 sq. ft. with an additional 10 sq. ft. vestibule for a total footprint of 47 sq. ft. This is an advantage when camping in heavily forrested areas.
There are many two person backpacking tents on the market but my research shows that most of them that approach this floor area, have a footprint upwards of 60 sq. ft. and the ones with footprints comparable to the Seedhouse SL3, won't fit two people comfortably nor accomodate my long body. As a bonus, most free standing, two person backpacking tents weigh at least a pound more.
The only negative thing I have to say about this tent is that it takes up a lot of room in your pack (21"x7"). Don't get me wrong, it's not a tent for an expedition up Everest nor is it as light as a tarp & bivy, but benefits per pound of this tent are hard to match!
I give it an unreserved 5.
