Alpinestars GP Plus R V4 Rideknit perforated Motorcycle Leather Jacket

The GP Plus R V4 RIDEKNIT® Leather Jacket is optimized for superior freedom of movement and rider comfort, and features extensive race-derived features and materials including a dedicated ‘Sport’ fit with pre-curved arms for maximum riding performance, and race-proven protection on the shoulders and elbows.

Features:

Alpinestars composite stretch technology, A-CS® Plus, stretch panels on the torso for exceptional breathability, comfort, and freedom of movement, as well as delivering a lighter weight and a lower profile than a traditional leather accordion panel (the A-CS® Plus panels are about 9% lighter than leather panels). Another key advantage of using A-CS® Plus is its superior stretch performance; A-CS® Plus has about 30% elongation, and offers an increase in tear resistance of 300% compared to HRSF (Hyper Resistant Stretch Fiber), and an increase in cut resistance by 600% versus leather
1.3 mm ‘Race’ grade leather construction for the optimum blend of abrasion resistance and comfort
RIDEKNIT® engineered inner arms; RIDEKNIT® combines high abrasion and tear resistance with high flexibility, comfort and mechanical stretch while still delivering superior comfort and high levels of breathability
extensive technical stretch panels under the arms, on the inner arms, and around the neck for an optimized fit
dual density DFS shoulders for superior friction control
GP Lite elbow armor for impact protection in a key area

How to measure your height:

1 Shoulder width

Measure your shoulder width across your back from the outer edge of one shoulder to the outer edge of the other. Stand upright and let your arms hang relaxed at your sides. Guide the tape measure from shoulder point to shoulder point across the upper back and make sure it does not slip.

2 Chest circumference

Measure your chest circumference at the fullest part of your chest. Run the tape measure horizontally around your upper body under your arms. Make sure the tape stays level and breathe naturally without puffing out your chest.

3 Waist

Measure your waist at the narrowest part of your torso, usually just above your belly button. Stand upright and keep breathing normally while you place the tape measure horizontally around your body. Make sure the tape is not digging in but also not too loose, so you get a realistic measurement.

4 Hips

Measure your hips at the widest part of your buttocks. Stand upright with your feet about hip-width apart and place the tape measure horizontally around your body. Make sure the tape stays at the same height all the way around and does not slip up or down.

5 Arm length

Measure your arm length from the outer shoulder point to your wrist. Let your arm hang naturally and relaxed at your side. Run the tape measure along the outside of your arm down to the wrist.

6 Inseam

Measure your inseam from the crotch down along the inside of your leg to the sole of your foot. Stand upright, ideally without shoes and with your legs slightly apart. Run the tape measure straight down and make sure it does not slip.

7 Outseam

Measure the outside leg length from your hip down the outside of your leg to the sole of your foot. Stand upright and barefoot with your legs naturally straight. Place the tape measure at the side of your hip and run it straight down to the sole. Make sure it stays close to your body and does not slip.

8 Thigh

Measure your thigh at the fullest part. Wrap the tape loosely around your leg without pulling it tight. For an accurate result, stand relaxed and distribute your weight evenly on both legs.

정말 니쁘고 좋습니다.

일단 색감부터 너무 좋고, 한국에서는 레드색상 48사이즈를 그 어디에서도 구할수 없어서 구매했습니다. 디자인이 제가 샀던 어떤 레이스핏 자켓보다도 이쁩니다. 다만 약간 팔뚝이 너무 꽉껴서 살짝 아쉽지만 너무너무 마음에 듭니다.

Beautiful looking Jacket - Get all the looks and enquiries.

Ordered the Black/White as the only variant available in NZ is Black/Neon. I'm 5'10", 87kgs - ordered up a size from my usual 54 to 56 as I have a Tech Air 5 plasma underneath. Fits perfectly, I'd say for me this is Road race fit not Track fit. (Not too tight but definitely not saggy) Truly is a looker and so comfortable!

Erstklassige Lederjacke!

Habe diese tolle Jacke für meinen Mann gekauft. Das Material dieser Jacke ist der Hammer!!! Super weich ,sehr angenehm zu tragen,top Verarbeitung 👍 Man sollte sie aber eine Größe kleiner bestellen, sie fällt etwas weiter aus ,als herkömmliche Modelle von Alpinestars.
