GSM stands for grams per square metre and measures the weight of the fabric. At 470 GSM, the Realtree APX Adventure jacket uses a heavier, more durable fabric combined with a Sherpa fleece lining for increased warmth and protection.
It’s best suited to cooler conditions and situations where you want more warmth and protection than a traditional lightweight softshell, while still maintaining the mobility and versatility of a softshell jacket.
A higher GSM doesn’t automatically mean an extremely warm or bulky winter jacket. GSM measures fabric weight rather than insulation, so the APX remains a versatile layer, perfect for Fall, Winter and Early Spring rather than a heavily insulated parka.
