Nature hike is a knock off brand, sure they can keeps costs lower because they have no R&D. Yes it's the same style but then that would be like saying all 2 pole dome tents are a knock off.
The likes of nature hike can say something is 40d but it might not be, where if known brands lied that could ruin them, with nature hike you'd shrug and move on.
My Hubba Hubba copy is actually a 'Wolf Wise' brand.
At 1/5th of the price its worth the 'risk' and when it turns out (with a few simple modifications) to be perfectly functional its a good buy.
They have exemplary customer service.
When I received the tent (next day delivery) I tried erecting it biut one of the pole 'nipple-ends' would not fit thru the 'eye' in the Footprint, or the eye in the tent-tab'.
I contacted (by email) Wolfwise and they told me "very sorry, we will send you a replacement by overnight express"
Next morning and a parcel arrived - I thought "that's a bit big for a pole-end nipple' and when I opened it up it was a complete replacement tent - COMPLETE - poles, tent, footprint, flysheet, guy lines , everything.
I contacted them and asked how they wanted the 1st one returning and they said "keep it for the inconvenience we have caused you".
I located some pole-end nipples on ebay (I think about £2 for 5) so now have 2 fully functioning tents for 1/5th of the price of 1x MSR.
Me, Happy ?
