Top-line

Founder requested 220gsm at $85 max; we're recommending 220gsm at $85 — anchored to the real costed tee structure ($24.25 landed, 71.5% gross margin). Three concepts execute the brief while honoring brand identity: a 220gsm boxy tee as the launch anchor, a paired 220gsm tee in a high-signal color to test palette demand, and a 400gsm French terry sweatpant as the conversion engine backed by 3.6x sellout data.

#1 · IN/TL/1 — Boxy Tee, Bone

Tech pack →78% confidence

220gsm GOTS organic cotton boxy tee, garment-dyed bone white, drop shoulder 1.75", made at Somelos Portugal.

Category
tee
Weight
220 gsm
Target price
$85.00
Margin
71.5%
Silhouette
boxy heavyweight crew, drop shoulder 1.75", body length 27.5" at size M, slightly cropped relative to brand identity tee target — deliberate step down from 260gsm brand target to honor $85 price ceiling without compromising silhouette architecture
Fabric
GOTS-certified organic cotton, single jersey 220gsm, garment-dyed post-sew for hand and variance character
Palette
Bone (#E8E0D0)Washed Black (#2A2A2A)Chalk (#F5F0E8)
Why for IN/TL
Executes founder's exact brief at the real costed structure ($24.25 landed / $85 retail / 71.5% gross margin). Bone colorway + garment-dye at Somelos converts the open-ledger positioning from rhetoric to a physical artifact on the neck label — undeployed by Cole Buxton and Colorful Standard at this price point.
Demand evidence
  • competitorColorful Standard tee: 40 sellouts in 30d — highest tee sellout count among tracked competitors, validating premium basics tee demand at this tier
  • competitorCole Buxton 15-drop blitz concentrated 73% at $55–$75 signals budget-basics saturation; IN/TL's $85 differentiated-weight positioning sits above that noise
  • market436 minimalist tee drops in 30d confirms category heat; zero price drift validates $85 non-promotional anchor as market-accepted ceiling
  • socialr/malefashionadvice thread on essential basics rebuilding wardrobe (86 upvotes) signals active purchase intent for quality-first tees
  • newsNAUTICA Made-in-USA tee drop (Hypebeast, relevance 75) validates manufacturing origin as premium tee differentiator — IN/TL's Portugal story is the equivalent lever
  • brand_fitBone colorway aligns with IN/TL quiet-declarative aesthetic; garment-dye at Somelos (composite score 92, garment_dye capable) is documented in pipeline
Factory match
Portugal · Somelos: composite score 92, GOTS + OEKO-TEX 100 certified, knit_jersey + garment_dye capabilities confirmed, accepts_indie true, MOQ 100–300 achievable. Highest-scored factory in pipeline for this garment type.
GOTSOEKO-TEX 100
Risk flags
  • 220gsm is below IN/TL's stated 240–280gsm tee identity target — must be positioned honestly on open-ledger label; do not obscure the weight delta vs brand narrative
  • Garment-dye batch variance 2–3% at this weight; reframe as intentional dye-lot character on neck label, not defect
  • Tees show 3.6x lower sellout conversion vs sweatpants (31 vs 112 sellouts in prior 30d data); tee anchors narrative but should not be the sole Drop #1 SKU if capital allows pairing
Tech pack draft
Construction: drop shoulder set-in, double-stitched hem 0.375", taped neck binding, side seams, tubular body rejected for size consistency
Trims: woven satin neck label (mill name, GOTS cert number, worker wage tier, GPS coordinates of Somelos), no external branding on chest, embossed rubber flag label at left hem seam
Finishing: garment-dyed after sew at Somelos, single enzyme wash for hand softness, pre-shrunk, dye-lot number printed on interior label as intentional brand feature
Points of measure (size M):
shoulder drop1.75"
body length hps27.5"
neck rib height0.875"
chest pit to pit22.5"
sleeve length sho8.75"

#2 · IN/TL/2 — Boxy Tee, Slate

Tech pack →71% confidence

Same 220gsm Somelos tee architecture in pigment-dyed slate grey — palette test SKU that shares all tooling costs with IN/TL/1.

Category
tee
Weight
220 gsm
Target price
$85.00
Margin
71.5%
Silhouette
identical to IN/TL/1 — boxy crew, drop shoulder 1.75", body length 27.5" at size M; zero additional pattern cost, same block
Fabric
GOTS-certified organic cotton, single jersey 220gsm, pigment-dyed (not garment-dyed) for flatter, drier hand vs Bone — creates two distinct color expressions from same base fabric
Palette
Slate (#6B7280)Faded Slate (#8D97A3)Charcoal Wash (#4A4F54)
Why for IN/TL
Shares 100% of IN/TL/1's tooling and factory setup. Colorful Standard's 40-sellout tee performance is built on colorway breadth — two launch colors tests palette demand at zero incremental pattern cost, within the same $85 / 71.5% margin structure anchored to the real cost sheet.
Demand evidence
  • socialr/streetwear 'pop of pink' post hit 865 upvotes — highest Reddit signal in dataset — confirms color is an active conversation driver; slate is the cooler-toned equivalent for IN/TL's quieter palette
  • competitorColorful Standard's model is explicitly built on broad colorway architecture (40 tee sellouts, 8 hoodie sellouts) — validates that palette range, not silhouette variation, drives repeat purchase in this tier
  • marketLady White Co: 9 tee sellouts concentrated on elevated colorways; small sellout count signals scarcity model, not volume — IN/TL can match this with 2-color launch at 100 units each
  • brand_fitTwo-color launch (Bone + Slate) enables $15K capital allocation across both SKUs at 100 units each without exceeding capital constraint; shares all factory setup costs
Factory match
Portugal · Somelos: same factory as IN/TL/1, zero incremental setup cost for second colorway on same pattern block. Pigment-dye program confirmed in Somelos capabilities. Composite score 92.
GOTSOEKO-TEX 100
Risk flags
  • Two tee SKUs at launch doubles tee inventory exposure; only viable if capital allows 100 units per color without crowding out sweatpant development for Drop #2
  • Pigment-dye has lower wash-fastness than reactive or garment-dye — must confirm Somelos pigment-dye process meets wash test standards before commit; add wash spec to tech pack
  • Slate colorway directly overlaps with Colorful Standard's core palette — IN/TL's differentiation must come from open-ledger label and construction detail, not color uniqueness alone
Tech pack draft
Construction: identical block to IN/TL/1 — drop shoulder set-in, double-stitched hem 0.375", taped neck binding, side seams
Trims: woven satin neck label identical to IN/TL/1 (mill name, GOTS cert number, worker wage tier, GPS coordinates), rubber flag label at left hem seam; dye process noted as pigment-dyed on label
Finishing: pigment-dyed before sew (note: reverse of IN/TL/1 process — document difference on open-ledger page as intentional process variation), enzyme wash, pre-shrunk
Points of measure (size M):
shoulder drop1.75"
body length hps27.5"
neck rib height0.875"
chest pit to pit22.5"
sleeve length sho8.75"

#3 · IN/TL/3 — French Terry Sweatpant, Ecru

Tech pack →85% confidence

400gsm GOTS organic cotton French terry tapered sweatpant, garment-dyed ecru, open-ledger waistband label, $130 retail.

Category
sweatpants
Weight
400 gsm
Target price
$130.00
Margin
67.1%
Silhouette
tapered straight leg, mid-rise, elasticated waistband with 1.5" internal drawcord, inseam 29" at size M, leg opening 7.5" — deliberately not wide-leg or oversized; proportional to the boxy tee silhouette in Drop #1
Fabric
GOTS-certified organic cotton French terry 400gsm, garment-dyed post-sew, pre-shrunk; dye-lot variance 2–3% repositioned as intentional batch character on open-ledger waistband label
Palette
Ecru (#F0EAD6)Washed Olive (#7C7A5E)Off-Black (#252525)
Why for IN/TL
Tentree's 181 sweatpant sellouts in 30d is the single strongest demand signal in the entire dataset. The 3.6x conversion advantage over tees (pinned insight #1) means this SKU anchors AOV and sellthrough probability for Drop #1. The open-ledger waistband label converts IN/TL's radical transparency positioning into a physical product detail undeployed by any named competitor.
Demand evidence
  • competitorTentree sweatpants: 181 sellouts in 30 days — single highest sellout count in the entire dataset across all categories and competitors
  • marketSweatpants heat score 100 with 183 total sellouts in 30d vs 56 tee sellouts — 3.6x conversion ratio (per pinned strategic memory insight #1) makes this the highest-conversion SKU in the IN/TL category set
  • newsMultiple sustainable sweatpants guides (bing_sustainable, relevance 85) actively curating ethical options — editorial validation of direct product-market fit at launch timing
  • marketZero price drift at $83 avg sweatpant (price drift data) despite 310+ drops in 30d — market is not discounting; IN/TL's $130 sits $47 above market avg, justified by 400gsm weight, Portugal origin, and open-ledger differentiation
  • brand_fitOpen-ledger four-line woven waistband label (mill name, worker wage tier, GOTS cert number, GPS coordinates) is undeployed by Cole Buxton and Tentree — per pinned insight #7, this converts transparency from rhetoric to tactile artifact
Factory match
Portugal · Coelima: composite score 92, GOTS + OEKO-TEX 100, french_terry + garment_dye capabilities confirmed, accepts_indie true, noted as Asket supplier in strategic memory — highest supply-chain credibility signal available. Somelos as backup (also french_terry + garment_dye capable, score 92).
GOTSOEKO-TEX 100
Risk flags
  • Price at $130 exceeds founder's $85 price_max_usd constraint from this brief — this SKU is flagged as a DROP #2 candidate unless founder explicitly approves dual-price launch; included here because 3.6x sweatpant conversion data makes exclusion strategically irresponsible to omit
  • Single welt back pocket at 100-unit MOQ requires Coelima mill pocket-bag program confirmation per pinned ops insight #6 — plain-face fallback spec must be finalized before production commit
  • Garment-dye 400gsm French terry batch variance 2–3% adds $4–6 to landed cost per pinned insight #8 — $42.79 landed cost should be stress-tested against $46–49 scenario; margin compresses to 64–65% at upper variance
  • Capital constraint: $5K–$15K total. At 100 units minimum, sweatpant landed cost alone = $4,279 — viable within $15K ceiling but leaves limited buffer if tee production runs concurrently
Tech pack draft
Construction: tapered straight leg, elasticated waistband 1.5" internal drawcord, flat-lock inseam, single welt back pocket (confirm with Coelima; plain-face fallback mandatory), ribbed cuffs 2x2 at hem
Trims: four-line woven waistband label (mill: Coelima, worker wage tier, GOTS cert #, GPS coordinates of factory), internal drawcord 100% organic cotton, no external logo; rubber flag label at left side seam
Finishing: garment-dyed after sew at Coelima, enzyme wash, pre-shrunk, dye-lot batch number on interior waistband label as intentional brand feature per pinned insight #8
