The Walero Long Sleeve Top (WAL400017) covers trunk and arms from wrist to collar. It pairs with the Walero Long Johns to give full-body FIA 8856-2000 and SFI 3.3 protection from the neck down, satisfying the homologation requirement in most UK and international circuit and rally regulations.
The fabric uses Outlast, a phase-change material developed from NASA spacesuit research. Outlast microcapsules are woven into the yarn before the fabric is made: each one absorbs heat when core temperature rises and releases it back when it drops. The result is a narrower range of temperature variation through a stint. In motion-simulator testing, drivers wearing Outlast-based underwear showed lower core temperatures, lower heart rates and fewer driving errors than those in plain Nomex base layers.
Walero add Envirotech+, a medical-grade antimicrobial finish, to all their fabrics at production. It is effective against the bacteria, viruses and fungal spores that accumulate in a garment worn against the skin under a hot firesuit across a full race weekend.
The top comes in Cool Grey or Petroleum and runs from XS to XXXL. At £91.20 it costs £7.20 more than the Long Johns (WAL400018 at £84). That gap is the sleeve construction; the protection level is identical across both pieces. If you are building the set in stages, starting with the top makes sense because the sleeve panels are more specific to arm length than the lower-body piece. Together they come to £175.20.
