A desert garment brief should separate hot active periods from cool, windy or stationary night periods instead of averaging them into one climate label.
Frame the decision
Map day and night temperature, wind, activity, rest and carried layers, then define when the softshell enters or leaves the clothing system.
The chosen jacket should have a clear role in each use state and a realistic packed place when it is not worn.
Build the controlled worksheet
Keep these five topic-specific inputs together so the quotation, sample and inspection teams do not work from different assumptions:
- Day and night temperature range: state the requirement, reference, status and approval owner.
- Activity and rest periods: state the requirement, reference, status and approval owner.
- Base-layer interaction: state the requirement, reference, status and approval owner.
- Wind exposure: state the requirement, reference, status and approval owner.
- Packability: state the requirement, reference, status and approval owner.
Evidence to request
- Approved source or drawing for day and night temperature range
- Order-specific record covering activity and rest periods
- Written acceptance basis for base-layer interaction
- Controlled decision history for wind exposure
- Release evidence connected to packability
Evidence must identify the relevant product, material, revision or lot. Record any limitation, substitution or item still awaiting approval.
Risks to close before approval
- Over-insulating daytime movement
- Underestimating wind during stationary periods
- Selecting a bulky layer that users will not carry
Assign an owner, due date and written disposition to each unresolved risk. Do not allow an informal answer to replace a controlled revision.
Use the result in the RFQ
Attach the worksheet, quantity, destination, required date and current sample status. Ask the supplier to list assumptions and exceptions against the same five inputs.
