Training tank: Wholesale sourcing brief

Request a linked-opening return for the activity sample

Ask the garment developer to return one annotated front-and-back opening trace from the actual adult training-tank sample, tied to the action sequence the programme intends to review. Its purpose is to show how the two openings move as one upper-body shape, not to repeat a generic fabric enquiry or a position-by-coverage scorecard. Include the neutral outlines and corresponding action-state outlines using the same sample and landmarks. The buyer should be able to see which edge relationship changed, where the observation occurred and which pattern pieces the maker must reproduce next.

Identify the material and construction behind the trace

PF-121 is 92% recycled polyester and 8% elastane, labelled Moisture management + quick dry, with 130, 142, 154, 166 and 178 g/m² options. The SJ-102 reference identifies 95% cotton and 5% elastane single jersey, finished Enzyme + compacted, with recorded options of 170, 180, 190, 200 and 210 g/m². Record the offered article, weight, strip material, attachment and pattern references on the return. No weight option is identical across the lists. The functional finish and elastane percentages are not evidence of recovery, moisture performance, support or verified recycled claims for the finished tank.

Keep paired outlines tied to the same action instance

Give each neutral and action-state observation an identifier that links front and back views from the same sample condition. Record the adult reviewer, size, intended underlayer and action description with consent and appropriate review arrangements. Do not splice the best front position from one trial with a back view from another. If simultaneous views are not available, state the limitation and reproduce the condition consistently rather than implying a precision the evidence lacks. The return is a garment-development aid, not motion-capture certification or proof of safe performance in every exercise.

Mark coupled edge movement rather than isolated pass boxes

Ask the maker to trace neckline, front and back armhole edges and shoulder landmarks against the neutral references. For example, a hypothetical front edge that stays intended during reaching may coincide with a back opening lifting away; the return should preserve both effects. Do not close the front independently and discard the back observation. CottonWorks includes garment fitting beyond fabric-stage approval, supporting review of this assembled shape. The annotations should distinguish intended visible underlayer from an unintended edge change without inventing universal coverage limits or claiming that the tank provides support.

CottonWorks: Designing Knit Textiles — Developed knit material proceeds to garment fitting beyond fabric-stage approval. Linked-opening traces and paired-action return are original buyer guidance, not a motion-assessment standard.

Translate the return into an authorised pattern relationship

Have the designer identify which linked shape is accepted and which segment needs another proposal. The maker should name the front and back pattern revisions, finished shoulder width and edge operation needed to reproduce the chosen relationship. If a correction changes one opening, show what happened to its partner and the neckline. This is not permission to deepen every armhole until the action feels freer. Keep the intended adult coverage and underlayer role with the pattern, so the next sample responds to the coupled observation instead of replacing the product proposition.

Carry the accepted link into cutting and component quantities

Send the selected front and back patterns together to the cutter with the size distribution, strip requirements, direction and joining rules. Ask for the affected marker and edge-quantity recalculation if shoulder width or opening lengths changed. A reduced panel area is not a verified saving until the actual layout and components are assessed at the confirmed offered width. Keep any unapproved size or activity extension visible. Commercial price and timing still require a real offer; they should not replace the pattern relationship that the annotated return is meant to communicate.

Bound the handoff to the actual activity and cared state

Retain the accepted linked trace with its sample, underlayer, care-stage identity and outstanding technical questions. If a cared edge changes the relationship, request the relevant repeat rather than carrying the original neutral drawing forward unchanged. For a different activity, size pairing or underlayer, identify what remains unassessed. The output gives the maker a specific paired-opening target and gives the buyer a clear basis for the next sample, not a general athletic approval. It supplies no wicking, cooling, quick-dry, support or health guarantee, and the functional catalogue label must remain separate from claim evidence.
