Nordkraft Wear Denmark: Swim School Programme Climate and Heat Evaluation
Nordkraft Wear is a Denmark-based brand whose swim school programme is one of its most demanding programmes. Heat changes how a fabric behaves, so we evaluated the recycled nylon interlock in genuinely hot conditions for Nordkraft Wear, based in Denmark.
Nordkraft Wear: Recycled Nylon Interlock in use during daily pool sessions for children and adults
Evaluation background
The programme covers training swimsuits, swim shorts and rash guards, used for daily pool sessions for children and adults. The environment is chlorinated water and repeated drying cycles and the requirement written into the brief was chlorine resistance with reliable shape retention. Fabric was selected on that basis rather than on price alone.

Test environment
Sessions ran at 30 to 34 degrees with high humidity, which is the condition where sweat cannot evaporate and complaints begin. Garments were weighed before and after each session to measure retained moisture.
Thermal behaviour
The fabric held opacity above 96% at 30% extension, and skin temperature stayed below the control fabric across the session. That difference is what a wearer describes simply as feeling cooler.

Drying after the session
Garments were re-weighed at 30 and 60 minutes. The fabric released most of its moisture within the first half hour, which matters when Nordkraft Wear runs back-to-back sessions.
Comfort feedback
Wearers reported less cling and less chafe during daily pool sessions for children and adults. Both improvements come from moving moisture rather than storing it, which is why construction mattered more than any finish in this test.

Verdict and recommendation
For hot and humid markets the recycled nylon interlock is the right choice, provided the pattern keeps the ventilation zones exactly where we placed them. For Nordkraft Wear the practical next steps are to keep the current specification for the repeat, retain the shade standard, and issue AATCC 183 results with every lot so any claim can be supported with data.
