REI Co-op Half Dome SL 2+ (REI #185632) — 2025+: Half Dome 2 Plus

Published · Researched 2026-09-21

2026 lineup note: The Half Dome SL 2+ was discontinued in 2025 and replaced by the redesigned Half Dome 2 Plus (45th-anniversary edition, MSRP $359 with footprint included). If you see "SL 2+" on a shelf in 2026, it's old stock or used. The new Half Dome 2 Plus is the current equivalent — roomier but heavier, and no longer "SL."

Version lineage (2023–2026)

• 2021–2023: Half Dome SL 2+ (first SL generation) — ~4 lb 13.5 oz min trail weight, 35.8 sq ft floor, footprint included, MSRP ~$329. Reviewed by OutdoorGearLab (~2023); praised for space, dinged for weight and for shipping with barely enough stakes.
• 2024: Refresh — REI lightened the SL 2+ to 3 lb 15 oz trail weight (Man Makes Fire, 2024: "more than a pound lighter than its previous version"), kept the roomy 2+ floor plan (35.8 sq ft, twin 11.3 sq ft vestibules, 42 in peak), sil-nylon fly per Adventure Alan's review, footprint still included. Backpacker named it a 2021 best all-around tent and was still recommending it on sale ($261, Oct 2024). MSRP $329.
• 2025: SL line discontinued; Half Dome 2 Plus (45th anniversary) launched — REI newsroom (spring 2025): all-new Half Dome 2 ($299), 2 Plus ($359), and 3 ($399). New HubCheck™ hub system for easier setup, more interior volume (near-vertical walls), nonfluorinated DWR, more durable ripstop fly, footprint included. Backpacker's 2025 "Hall of Fame" test: 44 in peak height, ~3 oz lighter than the outgoing non-SL Plus, 70D floor / 40D fly prioritizing durability over weight, ~4 lb 14 oz. The SL 2+ was officially discontinued (iheartpacificnorthwest, updated Sep 2025).
• Still a smart buy? Yes — a used/clearance SL 2+ at $150–200 is arguably the best value in this whole category: it's a full pound lighter than the new 2 Plus. Buy the new 2 Plus only if you want the latest hub system and max durability.

Overview

REI Co-op's best-selling tent line since 1980 — the "Goldilocks" tent (REI's words) that defined the 2-door/2-vestibule backpacking tent. The SL ("superlight") branch traded some durability for weight; the 2025 relaunch swung back toward durability and livability. Both are freestanding, double-wall, 3-season tents aimed at backpackers who want one tent for backcountry and frontcountry.

Key Specs

Pricing

• Half Dome SL 2+ MSRP: $329 (with footprint) — confirmed by Adventure Alan review (Aug 2026) and multiple used listings referencing "$329 new."
• Half Dome 2 Plus (2025+) MSRP: $359 (with footprint) — REI newsroom, spring 2025 announcement.
• Street: SL 2+ sold at $164.50 on REI member clearance (2023 deal) and $174.50 (Dealighted, recent crawl); new 2 Plus was $261–269 during 2024–25 sales per Backpacker. Current 2026 street price of the new 2 Plus UNVERIFIED — re-verify at rei.com.

In the Box

Tent body, rainfly, hubbed pole set, stakes, guylines, stuff sacks, footprint included (a Half Dome signature — both generations). New 2 Plus adds improved top-loading stuff sack and light-diffuser ceiling pockets.

Warranty

REI's 100% satisfaction guarantee — 1 year for returns/exchanges (confirmed via REI's spring 2025 newsroom: "backed by the co-op's 100% satisfaction guarantee").

Support & Parts

REI sells replacement footprints ($39.95 for SL 2+, $44.95 for 2 Plus) and supports pole replacement/repair in-store. Strong support reputation; parts availability for the discontinued SL 2+ will taper over time.

Community Verdict

The Half Dome is the most-recommended first backpacking tent on r/CampingandHiking — "best value, most livable" per Adventure Alan, and a Backpacker editors' staple since 2021. Owners love the palace-like interior and the included footprint; the persistent knocks are weight (the SL was still ~4 lb) and, on the older SL, a rainfly that sags and needs careful staking in storms. The 2025 non-SL relaunch split opinion: durability fans approve, ounce-counters mourn the SL. No fabricated scores.

Long-term durability & warranty-claim reality (enrichment — Sept 2026)

The Half Dome line is the durability-per-dollar king of mainstream 2P tents. Switchback Travel's 2026 test of the current 2 Plus: thicker 75D floor + 40D rainfly (up from 40D/30D) survived a 60-lb dog's claws with only a small mesh hole; "extremely hardwearing... will last several seasons." CleverHiker's 50-night test: "built a reputation over the years as a resilient shelter," now stronger. Recurring long-term complaints: mesh canopy is the vulnerability (snags/tears on thorns — thebrokebackpacker.com), occasional stiff zippers and low-quality stakes/cords (aggregation, TrueScoreReviews July 2026), and condensation in still conditions. OutdoorGearLab's older review warns PU-coated fabrics on budget tents degrade with UV/moisture exposure — long-term storage care is critical. Warranty-claim reality: REI's 1-year 100% satisfaction guarantee is the safety net — effectively a no-questions return window, not a lifetime warranty. Post-year-1, REI still sells parts but defect claims get stricter.

Version history — year by year (enrichment — Sept 2026)

• 2021–2023: Half Dome SL 2+ ("superlight") generation — ~4 lb 13.5 oz, 40D floor/30D fly, footprint included, ~$329.
• 2024: Refresh — lightened to ~3 lb 15 oz trail; DAC Pressfit aluminum poles; still "SL 2+".
• 2025: Renamed Half Dome 2 Plus; new HubCheck hub system, side-zip awning-capable fly doors, 75D floor/40D fly, footprint still included; trail weight crept back up (~4 lb 14 oz per Backpacker test); $329.
• 2026: Half Dome 2 Plus continues; REI sale pricing is the norm — never pay full $329 (member sales routinely drop it toward ~$165–230). The SL 2+ name is dead; listings still carrying it are old stock.

Head-to-head vs closest rivals (enrichment — Sept 2026)

• vs REI Passage 2 (/library/gear/tents-shelters/rei-passage-2/ — new this round): the Passage 2 is REI's cheaper 2P (~$199); the Half Dome 2 Plus is roomier and tougher with a footprint included. First-tent buyers on a tight budget take the Passage; everyone else takes the Half Dome.
• vs Marmot Tungsten 2P (/library/gear/tents-shelters/marmot-tungsten-2p/): similar price/weight class; the Tungsten includes a footprint too but is heavier (~4 lb 15.7 oz) and Marmot's street pricing is less predictable than REI's sale cycle.
• vs Kelty Late Start 2 (/library/gear/tents-shelters/kelty-late-start-2/ — new this round): the Late Start is the budget challenger (~$130–160); the Half Dome is the "buy it once" step up with far better fabrics and REI's return policy.

Care & maintenance (enrichment — Sept 2026)

PU-coated 75D/40D fabrics: the critical rule is storage — bone dry, loosely packed, away from UV; this is what determines whether the coating lasts 5 years or 10+. Seam tape is factory-applied; re-seal with urethane seam sealer only if tape lifts. The included footprint extends floor life on abrasive ground — use it. Mesh canopy: keep away from thorns and ember drift; patch small tears with Tenacious Tape promptly. Zippers: keep clean and occasionally lubed.

Buying traps (enrichment — Sept 2026)

• The rename trap: "Half Dome SL 2+" (2021–24) vs "Half Dome 2 Plus" (2025+) vs plain "Half Dome 2" — three different products. Verify the product name on the REI listing, not the review you're reading.
• Old SL 2+ stock is sometimes listed at the 2 Plus price — the 2 Plus is the better tent (thicker fabrics, better hub); don't pay 2 Plus money for SL 2+ stock unless it's deeply discounted.
• REI's $329 MSRP is a fiction for patient buyers — it routinely sells for ~$165–230 on sale. Paying full price is the trap.
• Trailspace complaint threads document REI reselling returned tents with mesh runs — inspect any "new" REI tent's mesh at unboxing and use the 1-year guarantee if it's flawed.

Community Verdict — additional voices (enrichment — Sept 2026)

Additional sourced voices: CleverHiker (50 nights, 2026) — upgraded 75D/40D fabrics make it "even stronger," footprint included; Switchback Travel (2026) — survived a 60-lb dog, "extremely hardwearing"; thebrokebackpacker.com — tougher rainfly than the MSR Hubba Hubba's, mesh is the vulnerability; TrueScoreReviews aggregation (July 2026, ~11,850 reviews): ~4.5/5 overall, "easy recommendation... without paying boutique prices," weight the main tradeoff. Longtime forum sentiment: the default "first real tent" recommendation on r/CampingandHiking alongside the Hubba Hubba. No fabricated scores.
