The Tarptent Rainbow Li is a one-person, wedge-shaped UL Dyneema backpacking tent (21.8 oz | 619 g) that is pitched with two carbon-fiber tent poles instead of trekking poles. Yes, that’s right. It uses tent poles instead of trekking poles, thereby increasing livability, headroom, and the amount of interior space inside. While the Rainbow Li is not freestanding, you can use trekking poles to make it into a freestanding tent when you have to set it up on wooden tent platforms, rock ledges, or sandy soil where it’s difficult to impossible to place tent stakes. This is a game-changer for me, eliminating nearly a pound of gear weight for those times when I’d otherwise bring my other freestanding tent on trips. I feel like the Rainbow Li is the forever tent I’ve been waiting for.

The Tarptent Rainbow Li is a spacious one-person tent with a single side door and vestibule. It comes with two carbon fiber poles, a long arch pole that spans the length of the tent, and a short cross pole that helps increase the tent width. The arch pole slips into a sleeve along the roof of the tent which makes for a very strong tent that is also easy and intuitive to set up.
The door is a side entry which I find easier for entering and exiting than a door on the end of a small tent. It only opens half the tent, so depending on if you prefer to enter a tent at the foot end or head end, you can set up the tent to accommodate your preference. There is enough room to stash a pack under one side of the vestibule. Both sides of the vestibule can be rolled up and held out the way with magnetic tabs. There is also a magnetic tab to hold the mesh door open, which is much easier to use than the toggle tie-backs on other tents.
The tent features a floating floor connected to the tent walls with mesh which makes the tent easier to pitch on uneven wild tent sites and also aids in cross ventilation. This is a signature innovation used throughout the Tarptent product line on their single-wall tents. The width of the perimeter mesh vents is also adjustable, allowing you to prevent splashback in heavy rain or to increase ventilation in fair weather.
The Rainbow Li also has dual peak vents that release hot air near the tent ceiling. When it’s raining, you can also porch the door (shown below) using the vestibule doors as awnings to enable airflow while preventing splashback (when rain hits the ground and bounces back into the tent.)
The Rainbow Li can be augmented with a gear loft (sold separately) for storing items overhead that attaches with hooks in the roof. This is often something I make myself, but at $17, I simply bought theirs. It has several small pockets and you can also store stuff on top of it as well. I highly recommend this add-on, although for the price of the tent I wish they would just include it.
Tarptent also offers an optional clip-in liner that hangs below the ceiling to prevent internal condensation transfer, much like the inner tent in a double-wall tent but without the sides, if that makes sense, although I didn’t buy it too.
The width of the floor is 36” and the length is 88”, so there is plenty of room to use a wide sleeping pad or for very tall campers. Pictured in the tent is a rectangular Nemo Astro Ultralight pad with dimensions of 20”x72”. The Rainbow Li also has plenty of headroom with 42” of vertical space in the center. The side walls are fairly vertical which helps improve the available space inside.
While the Rainbow Li is technically a semi-freestanding tent, you have the option of turning it into a freestanding one by connecting trekking poles to attachments at the tent corners. This is a big help if you find yourself camping on a tent platform or places where it’s hard to get stakes in the ground. It’s very easy to set up the tent this way. It requires a trekking pole length of 115 cm, so it is probably best used with adjustable length poles unless you happen to use 115 cm fixed length poles.
The Rainbow Li is made with ultralight Dyneema fabric which is highly waterproof and does not sag when it gets wet like silnylon. The floor of the tent is made with a thicker grade of fabric for added durability, enough that Tarptent says that an additional footprint is unnecessary except in extremely abrasive conditions. Given the expense of the tent, I use a lightweight polycryo groundsheet which offers a little extra protection and can help keep the tent cleaner for packing up (especially where you might pick up squashed slugs.)
The fly is a lighter-weight grade of Dyneema that is very light in color and fairly translucent, something to be aware of when camping with a full moon because it will light up the tent interior and can affect your ability to fall asleep.
The Rainbow Li comes with 6-round Easton tent stakes which provide robust anchors for the tent. In the past, I have mostly used basic triangular tent stakes. I find that in a side-by-side comparison, the round stakes collect less dirt and are easier to wipe off in the field.
The tent comes with a Dyneema stuff sack and there is also a small stuff sack for the stakes. Tarptent recommends folding and rolling the tent before putting it in the stuff sack. This is to help preserve the Dyneema fibers in the tent fabric, which can break down when creased by excessive folding.
You can roll the poles inside the tent or keep them separate if you prefer. In the field, when wet, I prefer to shake off as much water as possible, then simply do a quick roll and stick it in the bottom of my pack without putting it in the stuff sack. Then I separate it from my dry stuff with a pack liner. When rolling in the field, I really like having the tent laid out on a ground cloth to help avoid rolling debris into the tent.

It’s hard for me to find much about the Tarptent Rainbow Li that I don’t like. At 21.8 oz, the Rainbow Li weighs a few ounces more than the Dyneema Zpacks Plexamid Tent it replaces in my gear closet, but it is so much easier to set up.
The Rainbow Li is also one of the lightest tents you can get that doesn’t require trekking poles to pitch. Sometimes I like having a tent with more interior space, but more often than not, I like having a tent with a small footprint that fits in small places. This tent gives me that with plenty of interior space and livability and a quick and easy pitch in a lightweight package.
The Rainbow Li is a well-designed and high-quality product. I bought a slightly blemished version to save money, but the only thing I could find wrong was a seam patch that was not stuck down well. I stuck it down and it seems to be holding just fine. It’s a testament to Tarptent’s quality control that they didn’t sell the tent at full price.
