Overall Sprite 1 is very nice super light solo tent one could stretch into a fall by employing decent 20-0 degree F sleeping bag.
The J-space is able to accommodate Badlands75 backpack. Just enough place for my hiking boots at the opposite end. The tent is wide enough to fit extra 6-7 duffle bag alongside of the sleeping pad.
The construction is such that one could first pitch the fly even without the footprint - it snaps to the poles. Very nice feature! Than while out of the whether hang the main tent body or sleep without it.
Even though the leg-side poll could have benefited from adding 3-5 in radius it is still quite a superior alternative to even Gore-Tex bivy. Overall Sprite-1 offers a great protection from the rain and morning dew without sacrificing of air ventilation.
Some cautions although I would not consider them to be serious drawbacks.
Sprite-1 is not self standing but it only requires to stakes for initial pitch and once the fly and the tent clipped to the polls entire contraption could be moved with ease.
I would not recommend getting it if you were over 6'2 the lover end loop could have been 3-5 more in the radius. With the size 10.5 shoes I was just barely comfortable.
Enjoy!
