Our content plan row said 1/2/3/4 person. On my phone outside Detroit I opened Amazon for B09CT17FKB and the title read 1-Person only. That ten-second ASIN check saved me from ordering the wrong capacity.
Clostnature 1-Person Tent (ASIN B09CT17FKB, model Crux) is a freestanding solo backpacking dome with a 7'3" x 2'8" x 3' interior, 2.97 lb minimum trail weight, PU 5000mm fly, and 15" x 5.1" x 5.1" packed size. Amazon lists ~4.5 stars and Amazon's Choice as of July 2026.

Catalog mismatch: our keyword said 1/2/3/4 person, but verified Amazon on B09CT17FKB shows 1 Person Crux only (July 2026).
Calvin Reese's Verdict
Bottom Line
Clostnature Crux 1-Person Tent (B09CT17FKB) fits solo backpackers who want freestanding 2-pole setup, PU 5000mm waterproofing, and 2.97 lb trail weight near ~$68 with ~4.5 stars (July 2026).
I'd verify live price before checkout. Amazon fetch showed no featured offer on this ASIN in July 2026. The listing says 3-4 season, but I treat this as 3-season solo backpacking at 4.2 lb total kit weight.

Best For
- Solo backpackers who want freestanding walls without trekking-pole pitch skills.
- Budget hikers comparing 1P options under $70 in our roundup.
- Bikepackers and kayakers who pack a 15" x 5.1" cylinder and want PU 5000mm rain protection.
- First-time solo campers drawn to the 3-minute freestanding pitch claim on the listing.
Skip If
- You need 2 or 3 person floor space on this ASIN (1 person only on B09CT17FKB).
- You target sub-2 lb ultralight packed weight for fastpacking miles.
- You want two doors and dual vestibules (see Naturehike Mongar 2 review).
- You drive to camp with no weight cap (see car camping tips instead).
Pros
- PU 5000mm waterproof fly. 210T polyester rain fly with factory-sealed seams per Amazon copy.
- 2.97 lb trail weight. Minimum weight counts fly, inner tent, and 2 aluminum poles only.
- Freestanding dome. Two 7001 series aluminum poles cross for a 3-minute setup claim.
- 7'3" floor length. Listing cites room for a tall solo sleeper in a 2'8" width.
- Side vestibule. Store boots and pack outside the full-mesh inner on wet nights.
- Complete included kit. 14 aluminum stakes, 4 ropes, pole emergency repair kit, and carry bag ship in the box.
- GRS certified. Global Recycled Standard on the listing for recycled content.
Cons
- Catalog capacity mismatch. Plan keyword said 1/2/3/4 person; B09CT17FKB verified 1 person only.
- 4.2 lb total weight. Full kit with stakes and bag is fine for budget solo trips, not ultralight gram counting.
- 3-4 season marketing vs reality. Full mesh inner and 2'8" width suit 3-season trips, not harsh winter alpine camps.
- One door only. Wet-entry and midnight bathroom exits feel tighter than dual-door rivals.
- Narrow 2'8" width. Works with mummy bags; sprawlers feel pinched diagonally.
- Price volatility. Verify live Amazon price; featured offer was unavailable on fetch (July 2026).

Calvin Reese's Opinion
I'd grab the Clostnature Crux for a solo weekend on the North Country Trail when I want freestanding walls up fast and I'm not counting ounces past mile six.
I'd leave it home when I'm chasing sub-2 lb fastpacking targets or when I expect exposed ridge wind that needs a dome with aggressive guylines like our Kelty Grand Mesa 2 review habits.
I've learned to treat catalog 1/2/3/4 person labels like a wrong Google pin: verify the ASIN before you checkout. One door, mesh walls, and 210T polyester tell me this is a 3-season solo freestanding tent at a fair ~$68 price point. I pair floor comfort with our best sleeping pads review before I trust marketing copy alone.
My rule: if the ASIN on my phone is not B09CT17FKB, I do not checkout yet.
Amazon Reviews
Praise themes: fast freestanding setup, solid rain performance for the price, useful vestibule.
Recurring gripes: narrow width, condensation, wind needs full staking, and catalog size confusion on sibling SKUs.

Skip for multi-person capacity, ultralight sub-2 lb packed weight, or storm-chasing durability beyond a budget polyester dome.
