Tarptent Double Rainbow Li Review

Overview

The Double Rainbow Li is Tarptent’s Dyneema Composite Fabric take on its longtime best-selling silnylon Double Rainbow — same arch-pole blueprint, double vestibule, dual side entry, and hybrid single-wall-with-optional-liner design, but built with 0.51 oz DCF fly and 1 oz DCF floor to shave roughly a third of the weight off the original. It’s aimed at pairs of ultralight backpackers who want genuine two-person livability (not a “cozy” 2P that’s really a 1P) without hauling a heavy double-wall tent, and at solo hikers who want to spread out and don’t mind paying DCF prices for the extra room.

Performance

Space and livability. This is where the Double Rainbow Li earns its reputation. Multiple owners independently point out that it’s a full 50″ wide and can fit two 25″ pads, making it the only true 2P tent they found that allows for two 25″ wide pads. The floor is rectangular and non-tapered rather than the usual tapered-mummy 2P shape, and it’s symmetrical with no set head or foot end — a small detail that matters more than you’d think when you’re negotiating gear placement with a tent-mate every night. That said, opinions on “roomy for two” aren’t unanimous — I found at least one experienced user who felt it’s a lot for a 1-person tent, but it is tight for 2 people. My read: it’s genuinely one of the widest true 2P shelters out there, but “wide” doesn’t mean “spacious” once you factor in two sleeping pads, two packs, and two humans’ worth of shoulder room. If you’re used to a 1P tent for two, it’ll feel like a luxury upgrade. If you’re coming from a Copper Spur 2P or X-Mid 2, temper expectations.

Setup and versatility. The semi-freestanding pitch is a genuine selling point. One long-term user described being able to set it up in under a minute with rain pouring down, on any kind of ground, and free-standing with trekking poles, and specifically called out using it as a free standing tent on hard rock where stakes weren’t an option. Another Reddit thread echoes this, noting it sets up easy — far easier than an X-Mid 1 or 2 — and used as a semi-freestanding tent staked out, the pitch is always nice and tight regardless of terrain. For anyone who’s fought a trapezoidal tarp-tent pitch on rocky or sandy ground, that flexibility is a real quality-of-life upgrade.

Weather and condensation. The 8,000mm hydrostatic head and fully taped seams have held up in genuinely wet conditions — one owner reported using it through thunderstorms and being able to setup the tent in under a minute when the rain started to come down, while another with extensive AT/PA/ADK experience said it kept them dry and comfortable in very very rainy conditions. Condensation is the more consistent knock, as you’d expect from any single-wall DCF shelter. One owner who used it across desert parks noted they had to add tie downs for some desert winds and experienced a little condensation typical of DCF single-wall tents. The optional liner helps — several buyers added it specifically to manage moisture — but it’s an extra cost and extra weight on top of an already expensive tent.

Durability and pitch technique. The pole/pitch system has a documented failure mode worth knowing about: if the crossing arch poles aren’t pitched with the third, ground-supported option engaged, the structure can collapse sideways in wind. As one reviewer put it, this rarely mentioned pitch option is the strongest because it prevents the tent from collapsing sideways, and cautioned that this detail is on the older nylon Double Rainbow FAQ but not clearly documented on the Li’s product page. It’s a fixable issue with correct setup, but it’s exactly the kind of thing that trips up new owners.

Pros & Cons

Pros

• Genuinely wide 50” floor that fits two 25” pads — rare for a true 2P shelter
• Semi-freestanding with trekking poles means it pitches on rock, sand, or platforms where stakes fail
• Fast, forgiving setup even in bad weather, per multiple long-term users
• 765g packed weight is a big jump down from the ~1.2kg silnylon version
• Dual vestibules and dual side entry — no climbing over your tent-mate

Cons

• Costs over twice as much as the standard silnylon Double Rainbow for the DCF upgrade
• Single-wall DCF condensation is present, even if manageable with the optional liner
• Correct pitch technique matters — get it wrong and the arch pole setup can collapse in wind
• “Roomy for two” is relative; some users still find it snug once packs and pads are in
• Liner adds cost and weight if you want extra condensation control

Who Should Buy This

This tent makes the most sense for two hikers who prioritize interior width over ounce-shaving minimalism and who camp in variable terrain where staking isn’t always reliable — desert slickrock, coastal platforms, or rocky alpine sites. It’s also a strong pick for a single hiker who wants to stretch out with gear and doesn’t mind the DCF premium for the weight savings. If you’re tight on budget, the standard silnylon Double Rainbow gets you nearly the same footprint and livability for a fraction of the cost at roughly double the weight — a trade-off well worth considering before committing to the Li.

Verdict

The Double Rainbow Li delivers on its core promise: a genuinely wide, versatile, fast-pitching two-person shelter at a sub-800g weight that’s hard to match elsewhere. The condensation and pitch-technique caveats are real but manageable, and the price is the main barrier for most buyers rather than any functional shortfall. I’d rate it an 8.2/10 — excellent for the right use case, but make sure the DCF premium is buying you something you actually need before you pull the trigger.
