Constructed from Challenge Sailcloth’s new UltraTNT fabric, which promises to be lightweight, waterproof, and non-absorbing, Tarptent just announced three fresh tent options for folks looking to cut down on excess weight. Check out the Tarptent Scarp 1 Ultra, Double Rainbow DW Ultra, and Stratospire Ultra here…

The new UltraTNT fabric from Challenge Sailcloth is a three-ply laminate designed specifically for high-performance tarps and tents. The team at Tarptent partnered with Challenge Sailcloth on the development of the fabric over the last year and a half, and they are the first to release three tents made from the new material.

UltraTNT has a unique construction consisting of two layers of 0.25 mil PET film and their Ultra yarn inserted between them. The result is a lightweight (0.94oz/yard) fabric that is dimensionally stable, weighs less than SilNylon, and is waterproof and non-absorbing. The fabric can also be fully bonded at the seams for 100% waterproof tents and shelters. Tarptent is kicking things off with UltraTNT versions of three tents, including the Tarptent Scarp 1 Ultra, Rainbow DW Ultra, and Stratospire Ultra. Find specs and Tarptent’s flyby videos for each below.

Tarptent Scarp 1 Ultra

The Tarptent Scarp 1 Ultra features a double-walled construction, a single large arch pole, lots of interior space for one person, two large doors and vestibules, and requires six stakes for setup. The Scarp 1 Ultra weighs in at 1,260 grams (44.4 ounces) with carbon arch pole, solid interior, bags, stakes, cording, and struts, and it costs $579 USD. For comparison, the SilNylon version weighs 1,376 grams (48.55 oz). The aluminium arch pole will save you $20, and there are optional crossing poles for additional support for high wind and snow loads and a fully freestanding set up. Check it out here.

Tarptent Double Rainbow DW Ultra

The new DoubleRainbow DW Ultra is based on the popular design of the original version but saves around 15 grams when using the carbon arch pole. It’s a two-person, three-season tent with a double-wall construction, room for two wide sleeping pads, two large doors and vestibules, and it requires six stakes for setup. The Double Rainbow DW Ultra weighs in at 1,150 grams (40.55 ounces) with carbon arch pole, struts, stakes, cording, and bags, and it costs $539 USD. Just like the Scarp, the aluminum pole will save you $20. Check it out here.

Tarptent Stratospire Ultra

The Tarptent Stratospire Ultra is a larger and stronger version of the classic Stratospire Li. It has a lower fly edge and a longer, wider interior that will fit two long/wide pads. The Stratospire Ultra has a low-drag shape that holds up great in windy conditions, requires six stakes, has a double-wall construction, and sports two doors, vestibules, and vents. It’s designed to be set up with trekking poles, but Tarptent offers an optional pole set for those traveling without them. The Stratospire Ultra weighs in at 1,125 grams (39.7 ounces) with stakes, bags, struts, mesh interior, and apex guy lines. Adding two of Tarptent’s carbon poles would add another 222 grams to the setup. Check it out here.
