The SilOctapeak F8 is a much larger version of the V4a.
The inner tent offers huge space for 4 tall sleepers, it has got a 10cm high bathtub-floor. Through the two entrances and two vestibules you can enter the tent with the entrance only half opened, so no rain will get into the inner tent. You can use two separate 1-person inner tents like the V4a inner inside inside the F8 flysheet, to create parted sleeping rooms or decide to use a two person inner tent like the V8 inner.
The lower part of the nest is made from a plain Tafetta fabric to reduce airflow, and in combination with the variable pitching height and two closeable top vents the venting can be contolled perfectly. All connections between inner and outer tent, as well as to the pegs are highly adjustable, so you have a high degree of freedom where to put the pegs. The top-loop can be used to pitch the tent with outer poles, or to hang it from a tree.
The F8 is delivered with 8 pegs for the minimal setup, and in case of heavy weather it offers 23 pegging points.
The flysheet is made from 40D ripstop nylon with SI/PU coating, all the major seams are doubled with tough webbing to increase the stability.
The SilOctapeak F8 is delivered with stuffsac, velcro, seam sealant and 8pcs aluminium V-style pegs. You need an additional pole of ~185cm height, for example the Tarp Pole 197.
