G'day Emily,

Hiking tents are generally pretty good in wind, because they are low to the ground and fairly aerodynamic.
You shouldn't have too many issues with the grasshopper doing coastal trips, but for increased enjoyment finding a sheltered spot is best, and orient your tent with the head or foot end facing the direct of the wind, not the side.

G'day Andrew,

We currently don't stock spares for this tent though Black Wolf stocks a repair kit called a Tent Replacement Pole Kit. This includes 3 x Aluminium pole sections to repair part of the tent poles, not a full set but this would be the best option. 

G'day Carmen,

There are two vents on this tent, but there's no footprint available.  I am aware of a hiker who has used their Grasshopper UL 2 for 18 months on regular trips, largely setting up on granite rock with no issue...it shouldn't be too bad without a footprint, but if you want to add one to your kit there's nothing that will fit exactly, but the Zempire Zeus, or MSR Universal with be the closest options

G'day Keanu,

Yep, it is - generally dome style hiking tents are free standing, meaning they can be set up without needing pegs and guy ropes.  The only consideration is to have functioning vestibules, you'd need to use a rock (or similar if pegs are not an option), to tension those out.  If not you can still absolutely use the tent.
Hope that helps.

G'day Jeff,

The storage back fabric is water resistant, but the bag itself isn't waterproofed - eg. not seam sealing and the bag opening is a pull chord.
You'd probably be ok in light showers, but in anything prolonged or heavier you'd probably want to use a fully waterproof dry sack.
