check out MIER on amazon/Ali, its the same tents as far as I can tell. More buying options at any rate. amazon link
I'd suggest researching MIER tents as well, they might be similar amazon link
I am looking at this for temporary tent until Gossamer Gear gets “The One” back in stock, The the Ultra Light Mier 1P Tent on Amazon was what I was looking at, I was just curious if its even worth the money, its so cheap I thought it would work. Any experience with this tent and advise on possible other tents like it? Ill link the tent below.
MIER Ultralight Tent 3-Season Backpacking Tent for 1-Person or 2-Person Camping, Trekking, Kayaking, Climbing, Hiking, (exclude Alpenstock) https://www.amazon.com/dp/B07FM7GZLG/ref=cm_sw_r_cp_api_glt_fabc_RNSQYR00EKHS5NQDQSM1?_encoding=UTF8&psc=1
I went off of the Amazon listing because that's where I'll be ordering it from. If you look at the Lanshan 1 pic, it states it's a 2.5ft / 30" width for the rectangular portion alone. It doesn't state what the peak width is when you account for the asymmetrical portion. https://www.amazon.com/dp/B07FM7GZLG/ref=cm_sw_r_cp_apa_i_h4a2Db7MRQDP4
That asymmetrical portion is important to me because I will have a dog that I would like to keep in the inner tent with me. If it weren't for the dog I would just get a Borah CF bug bivy. It's frustrating that the asymmetrical portion isn't measured anywhere that j can find.
Can you link to where you got your numbers for the Lanshan? On the Amazon listing I posted it lists it as a 53"ish inch total width, not 71".
Another option I figured out that worked really well for me was using the inner from this cheap amazon knockoffs.
It's not the lightest, but unlike the serenity it's actually shaped like a hexagon and makes use of the extra space.
If you are under 6ft, then the 3F UL Lanshan 1 would closely fit the bill. If you need it fast, the Meir version (same tent) is 109$ on amazon. Can usually get it on aliexpress for cheaper, but tarrifs are raising the prices.
