Nordkraft Wear Portugal: Yoga and Pilates Studio Programme Climate and Heat Evaluation
Nordkraft Wear is a Portugal-based brand whose yoga and pilates studio programme is one of its most demanding programmes. Heat changes how a fabric behaves, so we evaluated the seamless circular knit in genuinely hot conditions for Nordkraft Wear, based in Portugal.
Nordkraft Wear: Seamless Circular Knit in use during mat-based studio sessions and long holds
Evaluation background
The programme covers leggings, crop tops and studio shorts, used for mat-based studio sessions and long holds. The environment is warm, humid studios with sustained low-load stretch and the requirement written into the brief was a soft hand with full coverage through every pose. Fabric was selected on that basis rather than on price alone.

| Test method | ASTM D4966 |
| Additional note | zoned structure knitted directly into the tube |
| Certification | OEKO-TEX Standard 100 |

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 above 20000 abrasion cycles without yarn breakage, 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 mat-based studio sessions and long holds. 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 seamless circular knit 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 ASTM D4966 results with every lot so any claim can be supported with data.
