Gossamer Gear The One Review

Overview

The One is a single-person, fully enclosed shelter made of silnylon that relies on two adjustable trekking poles (or two custom-length poles purchased separately) for setup.

At 502g / 17.7 oz,

it sits firmly in the realm of Dyneema Composite Fiber tents — but is priced in a way that puts all of those to shame, making it something of an anomaly in the ultralight category.

The latest version has been refreshed with Gossamer Gear’s proprietary ClearSkies™ fabric, a meaningful upgrade in both durability and waterproofing. This is a shelter built for weight-conscious thru-hikers and solo backpackers who already carry trekking poles and know how to pick a campsite.

Performance

Weight & Packability

This is where The One makes its case most convincingly. Comparable silnylon trekking pole tents weigh anywhere from 20 to 32 oz — somehow, The One comes in substantially lighter than this. And because it’s silnylon rather than DCF, it packs down smaller: the silnylon version rolls to 5” × 10”, while the DCF variant comes in at 14” × 4.5”. That 5” × 10” footprint fits inside most ultralight packs without strapping to the outside, where thin fabrics are most vulnerable to snags.

Interior Space & Livability

The One punches well above its weight class for livability. The trekking-pole architecture delivers an amazingly spacious interior — the 45” (114cm) peak height is way higher than almost all other one-person tents, even dome-style designs known for their spaciousness. The inside is surprisingly spacious — there’s plenty of room for a person much larger than most to sit up and move around. This isn’t one of those one-person tents that feels like a coffin.

That said, the floor tapers aggressively. While the headroom is generous, the floor space is a bit on the small side — 33 inches wide at the head end, tapering to 21 inches at the foot end — making it less useful for those who prefer wider rectangular sleeping pads. Hikers over 6’ should pay attention: at 84 inches of floor length, it fits a 77-inch pad reasonably well, but when lying on the pad, feet can end up about one inch from the side wall. Use the head and foot guyout points — they buy you a few critical inches of clearance.

The interior is well-appointed. There’s a large side mesh pocket positioned above the top of the bathtub floor, where it’s safe to stow glasses or a phone without fear of them getting crushed if you roll around at night.

The clothesline at the top of the tent is a handy touch for drying damp socks or hanging a headlamp.

Setup

The catenary-cut sides make getting a good pitch easy. Setup is quick and the tent is quite roomy for a one-person tent.

Most users report it takes one or two practice pitches to dial in — after that it goes up fast.

It comes factory seam-taped, so there’s no seam sealing required before use. Like most ultralight tents, however, good campsite selection skills are crucial to minimize floor abrasion and wind exposure.

Weather Resistance & the ClearSkies™ Upgrade

This is where the conversation gets interesting, and it’s worth separating older reviews from what the current tent actually delivers. Earlier versions of The One used a thinner 10D silnylon with a modest hydrostatic head rating, and reports of water ingress in heavy rain were a recurring theme. The ClearSkies™ fabric is now being rolled out across updated versions of The One, The Two, and The Twinn Tarp. ClearSkies™ combines 15D PFAS-free recycled Robic nylon with a 20D dope-dyed ripstop grid. An advanced silicone and PU coating fully seals the fabric, and the resulting hydrostatic head rating is 4,923mm — surpassing the average water resistance of a three-season tent. When tested against the previous fabric, ClearSkies™ performed 35% stronger in tensile strength and 2.35 times more water resistant. That’s not marketing fluff for a cottage brand — it’s a meaningful step up.

That said, single-wall physics don’t change with a new fabric. The tent can’t be pitched flush to the ground, so there’s always some risk of water ingress from below, particularly in heavy horizontal rain. The back side — without a door — is also particularly vulnerable in heavy rain, as it has an open, awning-like structure protecting the mesh inner. Wind orientation matters: when pitched properly the stability is as good as many freestanding three-season tents, in part because the tall walls are angled to deflect wind — but Gossamer Gear recommends pointing one end into the wind and finding a sheltered campsite.

Condensation

Single-wall condensation is real and unavoidable on cold, humid nights. Single-wall shelters will always experience some condensation. The One addresses this with a retractable vent — open it on calm nights for airflow, or use the velcro stays to seal things up in heavy weather. There’s a noticeable air gap between the ground and the front and rear vestibules — this is intentional, promoting better air circulation. In practice, users at high elevation or in very cold conditions report heavier condensation buildup. If you’re camping above treeline on cold nights, budget mental space for a damp morning.

Footprint Recommendation

The thin material means this shelter requires a bit more care. Gossamer Gear recommends using a polycryo or nylon groundsheet to extend the floor’s lifespan.

A large sheet of Polycro cut to size creates a footprint that weighs less than two ounces

— it’s the right call.

Pros & Cons

Pros

• Sub-500g weight in silnylon is genuinely remarkable; competitive with DCF tents at a fraction of the cost

• Trekking-pole architecture creates a surprisingly airy interior — 45” peak height beats most 1P dome tents

• Comes factory seam-taped — no pre-trip seam sealing required

• One of the smallest packed options available; Gossamer Gear rates it at 5” × 10” rolled

• ClearSkies™ fabric upgrade delivers nearly 5,000mm HH — a major durability and waterproofing improvement over older versions

• Quality of construction is top-notch: clean lines and smooth zippers

Cons

• The nearly vertical back wall combined with a partial vestibule means it has one direction that is absolutely terrible in the wind

• Floor tapers sharply to 21” at the foot — not ideal for wide rectangular pads or restless sleepers

• Single-wall condensation is unavoidable in cold or humid conditions; the vent helps but doesn’t eliminate the issue
• Non-freestanding: requires staking and good tent-site selection — a hard stop for rocky or sandy terrain

• Door toggles and elastic loops are tiny, making them harder to manage with cold or wet hands

• 84” length is tight for hikers over 6’1”

Who Should Buy This

The One is ideal for backpackers who prioritize ultralight gear and are comfortable with the trade-offs: using trekking poles for setup, less interior floor space, delicate fabrics, and the condensation realities of single-wall design.

It’s particularly well-suited to

thru-hikers drawn by the combination of low weight, competitive price, and generous headroom.

If you’re a trekking-pole user heading through dry-to-moderate conditions on trails like the PCT, CDT, or JMT, this tent makes real sense. It’s not the right call for shoulder-season alpine trips, sustained Pacific Northwest monsoon weather, or hikers who want the set-it-and-forget-it simplicity of a freestanding tent.

Verdict

The Gossamer Gear The One has earned its reputation as the benchmark value shelter in the ultralight category — and the ClearSkies™ fabric update makes the current version meaningfully better than what most existing reviews were testing. The interior livability-to-weight ratio is hard to beat in silnylon, and the price sits well below DCF competition. The trade-offs are real — wind vulnerability on the back wall, single-wall condensation, and a demanding fit for taller hikers — but none of them are hidden. Go in with clear expectations and good campsite judgment, and this tent will carry you a long way. 7.5/10.
