This black and white suit combines lightweight kangaroo leather in high-flex areas, including the arms, hips, and abdomen, with race-grade bovine leather for a balanced blend of protection, durability, comfort, and reduced weight. Its engineered race fit uses highly pre-curved arms, legs, and body panels to support an aggressive riding position and unrestricted movement on the motorcycle. This model is sized US 48 \/ EU 58 and is identified by manufacturer and vendor part number 3156822-12-58.\u003cbr\u003eThe suit features strategically placed stretch panels around the chest, inner arms, crotch, and back of the legs for improved flexibility and strength. MATRYX structural panels across the thighs, abdomen, chest, and back hump provide high mechanical resistance to tearing and abrasion while promoting ventilation in a thin, lightweight package. The lower-leg MATRYX construction is covered with high-performance polyurethane and is derived from MotoGP development for improved airflow, reduced weight, and freedom of movement. Strategic perforations on the arms and legs further support airflow, while the Cool-iR treatment helps reflect infrared sunlight to reduce heat buildup inside the suit.\u003cbr\u003eProtection is supported by GP DFS armor, replaceable elbow sliders, internal race-spec GP-R Lite armor, and Bio-Flex Race hip armor. The suit is Tech-Air ready and can accommodate the Tech-Air 10 Airbag System with extended hip protection, sold separately. A dedicated left-forearm slot accommodates the system's wireless LED display. An internal paddock waist hook helps keep the suit positioned when moving around the pit area with the upper portion lowered. The zippered, detachable short-leg comfort liner is treated with Polygiene for long-lasting freshness and convenient maintenance. The Alpinestars GP Tech v4 is suitable for riders seeking an advanced leather racing suit for compatible motorcycle track and racing applications.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eKangaroo leather in high-flex zones combined with race-grade bovine leather for lightweight performance, durability, and comfort\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eEngineered race fit with pre-curved body, arms, and knees for an aggressive riding position\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eStretch panels around the chest, inner arms, crotch, and back legs for enhanced mobility and strength\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMATRYX structural panels provide ventilation and resistance to tearing and abrasion with a thin, lightweight construction\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMATRYX lower-leg panels with high-performance polyurethane covering support airflow and freedom of movement\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eTech-Air ready and compatible with the Tech-Air 10 Airbag System, sold separately\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eGP DFS armor, replaceable elbow sliders, GP-R Lite armor, and Bio-Flex Race hip armor provide track-oriented protection\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCool-iR treatment helps regulate interior temperature by reflecting infrared sunlight\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eStrategic arm and leg perforations improve airflow during riding\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDetachable short-leg comfort liner with Polygiene treatment for long-lasting freshness\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSize: US 48 \/ EU 58\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eBrand: Alpinestars; model: GP Tech v4; manufacturer and vendor part number: 3156822-12-58\u003c\/li\u003e\u003c\/ul\u003e","brand":"ALPINESTARS","offers":[{"title":"Default Title","offer_id":49389982351595,"sku":"28011520","price":1999.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0611\/3882\/9547\/files\/2485423.png?v=1789062623","url":"https:\/\/ctracingservices.com\/products\/alpinestars-gp-tech-v4-leather-suit-black-white-us-48-eu-58-part-number-3156822-12-58","provider":"Cascade Tire \u0026 Racing Services","version":"1.0","type":"link"}
