【Latest 2025 Quality!】 The inner shell is upgraded with denser EPS, offering high water resistance, light weight, and strong shock absorption! Boasting long-term stable insulation performance, proven to have almost no degradation in the industry. It is also resistant to mold and corrosion, making it a reliable insulation material for long-term use. The outer shell uses rigid, bend-fatigue-resistant ABS, which is resistant to heat and impact, and has excellent surface gloss and colorability, providing a high-quality texture. 【3-in-1 All-Around Protection + 2 Sets of Shock-Absorbing Liners】 The greatest design feature of the Rocky Goose helmet is its ability to systematically absorb external impacts across the entire helmet (outer shell, inner shell, and shock-absorbing liners). In addition to the shell, the shock-absorbing liners inside absorb significant impact, minimizing the impact transmitted to the head. Furthermore, unlike some other companies' liners or thin liners, the Rocky Goose helmet package includes two full sets of 8 mm liners (including front and temples, crown, back of the head, and chin pads). It also has excellent sweat absorption and can be removed and washed, making it easy to maintain a clean condition. 【Both Coolness and Safety】 The ventilation holes provided at the front, back, and top take in a lot of air and quickly exhaust stuffy air, providing good ventilation and coolness! The all-around adjustable adjuster for the head, side ears, and under the chin eliminates head slippage and improves the hold and stability by fixing it in a comfortable position. This is a bicycle helmet that combines coolness and safety! 【Latest Asian-Specific Model】 Most bicycle helmet models on the market are currently Western models (oval). This is because Westerners have long heads (narrow width and protruding back of the head). However, Asians have short heads (wide width and flat back of the head), so wearing Western models can cause pressure on the temples and poor fit. The company's Asian-specific model (circular) fits the Japanese head shape perfectly, providing a comfortable fit while better protecting the entire head. 【CPSC Safety Standards + ASTM Safety Standards + 12-Month Warranty】 The CPSC standard is one of the standard safety standards for bicycle helmets distributed in the United States and around the world. The ASTM standard is an internationally recognized standard established by ASTM International, the world's largest standardization organization.
