Material & construction
| Fabric | GOTS-certified organic cotton, 260gsm single jersey, garment-dyed post-sew — Washed Black colorway requires reactive dye process on pre-treated white base |
|---|---|
| Silhouette | identical to IN/TL/1 — boxy heavyweight crew, drop shoulder 1.75", body length 27.5" at size M, ribbed 1x1 neck |
| Construction | identical to IN/TL/1 — drop shoulder set-in sleeve, double-stitched side seams and hem, taped neck binding, single-needle topstitch at sleeve hem |
| Trims | woven satin neck label (factory name, mill origin, worker wage range), debossed leather flag at left hem — identical to IN/TL/1 |
| Finishing | garment-dyed reactive black post-sew, double enzyme wash for hand and to reduce bleed risk, tumble dry test confirming <2% shrinkage and <5% color transfer on white cotton |
Colorway
Washed Black (#2A2A2A)
Points of measure (size M)
Specs as recommended. Grade S/L/XL using standard rules (2" chest/hem jumps for tee, 1.5" waist/hip for sweatpant). Tolerance ±¼" on critical dimensions.
| Point | Size M |
|---|---|
| shoulder drop | 1.75" |
| body length hps | 27.5" |
| neck rib height | 0.875" |
| chest pit to pit | 23" |
| sleeve length sho | 9" |
Recommended factory profile
| Region | Portugal |
|---|---|
| Required certifications | GOTS, OEKO-TEX 100 |
| Rationale | Same factory run as IN/TL/1 (Somelos or Coelima); second colorway added to same production order — no additional setup cost, incremental MOQ 100 units minimum; reactive dye for black requires separate dye bath but same sewing line |
Demand evidence
- competitorCole Buxton repeated ATHLETIC INC TEE 4x and BLANK tee 3x in same drop window — color/wash repetition on a single silhouette is the proven SKU velocity strategy in this category
- category_data402 tee drops in 30 days with heat score 100 — category depth (multiple colorways per silhouette) is how competitors maintain presence without launching new constructions
- brand_fitSecond colorway on same tech pack reduces tooling cost and factory setup time; shared production run with IN/TL/1 (Bone) lowers effective per-unit cost and maximizes $5k–$15k capital efficiency
- socialr/malefashionadvice thread interest in heavyweight tee construction and durability content signals male buyer preference for colorways that read as workwear-adjacent — Washed Black satisfies that segment without a new silhouette
Risk flags
Washed Black garment-dye is more prone to bleeding and uneven tone than Bone — requires strict dye bath control and pre-wash protocol; quality failure on black is more visible than on Bone
Running three SKUs simultaneously (IN/TL/1 Bone tee, IN/TL/2 Slate sweatpant, IN/TL/3 Washed Black tee) at minimum 100 units each pushes total capital requirement to $9k–$12k landed — tight against $15k ceiling
Lowest strategic differentiation of the three concepts — this is a capital-efficiency and assortment-depth play, not a differentiation play; only viable if IN/TL/1 production is confirmed and capital permits
Why this for IN/TL
Cole Buxton's 4x repetition of a single tee silhouette in one drop window is not noise — it is confirmation that colorway depth on a proven construction is the category playbook. IN/TL/3 is not a new idea; it is capital-efficient assortment depth that shares a tech pack with IN/TL/1 and lowers per-unit cost on the shared production run. Ranked third because it is contingent on capital headroom after IN/TL/1 and IN/TL/2 are confirmed.
