I'd go with the Marmot. It's probably ripstop fabric which is impressively tear resistant considering how thin it is. Just be careful to clear the ground of sharp rocks and sticks before setting it up. If your trip is this summer then you have more time to use it before then. If any issues in that time you can always go with something else.

My Big agnes Fly Creek UL1 is almost 10 years old and still going strong.

 

I like tarptent tents, super light and bomber. I use them for backcountry skiing, snow and high winds.
Double wall and they set up both inner and outer at the same time, so the interior never gets wet, plus it's faster.

I have about 60-70 or so nights in a Big Agnes Fly Creek, including probably half of those on bike trips and it's holding up pretty well. I feel like I should have a tyvek ground sheet but I have not and so far it's been ok.

 

Since Marmot is $400+ retail, and is made in either Vietnam or china, I purchased my latest lightweight tent from Aliexpress. I can't state yet how this one will hold up, but I will find out this summer. Carbon poles and stakes, appears to be well made.

I am laughing. I made this post about the ultralite tent I purchased from Aliexpress back in May. I used the Chinese tent on my 2 week Divide trail trip through Wyoming and Colorado. The cheap-*ss carbon pole connectors started breaking one-by-one. When I passed through Steam Boat Springs, I purchase a 2 person Big Agnes $550 tent. Very well made and designed just for bike camping. Very good tent.

 

I work for a pretty high end tent/backpacking company. The sad part of truly UL tents is they are considered wear items. The sli-nylon or sil-poly tents won't be as light as dcf and are usually 7d or 10d fabric. They can last a few years if cared for. The DCF tents-yeah they degrade and tear easily. It seems like the only time you hear the "high end gear" guys talk about this is in private. They won't discuss this stuff on their youtube channels. Saving a few onces is expensive!

 

My 1 pound 4 ounce tent had a short life span. It is not a storm shelter. Water proof, was short lived. I'll save it for weekend trips with no chance of rain.
Fly Creek will keep you dry for a long time. You know when the seam tape wears out and needs repairs. The fabric stays water proof. Fly Creek zippers start to have problems at 100 days. At 120 days the zipper is useless. Agnes has some customer service. Fix the zipper, possibly a loaner tent, maybe.
Your tent is not the best place to save weight.

Buy a titanium cup and cook on a 🔥 fire.

My current guess.
Tiger Wall 2 has two doors, and a straight zipper. 2.8 pounds. Is this the way to go for a months long journey?

A one pound tent is not a storm shelter on a long trip. If you have a three day weekend and a trail you want to ride, go for it.

 

I think there are 2 types of people out there -
First is the person who buys nice stuff (or even just stuff - could be a tent, mountain bike, car, etc etc) and takes care to not abuse it - they USE it but they put effort into not abusing, or at least caring for it - clearing out rocks/sticks etc etc or whatever the case may be depending on what the piece of equipment is. These people generally get more life out of their stuff in exchange for taking some care.

Other type will just throw the tent down, or use the equipment and let it take abuse because "it was designed for that" and it will wear out but that's OK because it wasn't designed to last forever.

Not saying one is right or wrong - but they type of person you are can help guide which equipment best suits you.

My opinion.

PS not saying the AliExpress tent would have lasted!
