Klim has built its name on gear that works when conditions get tough. Based in Idaho and known for technical riding apparel, the brand has become a go-to for serious adventure riders, dual-sport explorers, and backcountry snowmobilers. The common thread? Function over flash, and durability you can actually count on.
That thinking carries over into the second-generation Baja S4 series. This isn’t just summer gear—it’s a fully featured kit built specifically for hot, dry, and rugged conditions. The jacket and pants use Schoeller Dynatec mesh as their main material. It’s tough, tear-resistant, and flows a huge amount of air. Most of the outer shell is a single breathable layer, backed by a moisture-wicking liner. Even the pockets are laid out to avoid blocking airflow.
For added comfort, Klim integrates 1,000-denier Karbonite Micromesh in the stretch zones—around the shoulders, back, knees, and hips. These areas flex easily while still letting air in, which helps reduce fatigue during off-road riding. The jacket also includes a hydration pouch pocket designed to hold a 2-liter (0.53-gallon) Hydrapak bladder, ideal for long, dry rides.
Safety is a core part of the Baja S4’s build. Vented D3O Level 1 armor protects the back, shoulders, elbows, hips, and knees. Superfabric covers high-impact zones with ceramic-plated abrasion panels, giving the Baja S4 serious road-ready protection while staying lightweight and flexible. The Baja S4 gloves follow a similar formula, with perforated leather and direct-vent knuckle armor to keep your hands cool and shielded.
Need weather protection? The Baja S4 system pairs with Klim’s Enduro S4 overshells. These fully waterproof layers fit over the jacket and pants without messing up your mobility or airflow setup. They pack down small, making them easy to stash when not in use. Bonus points: the Enduro S4 jacket doubles as a solid camp layer—or even a pillow—when you’re off the bike.
For riders tackling hot climates and mixed terrain, the new Baja S4 lineup offers a balanced solution. It’s cool when you need it, tough when it counts, and adaptable when the weather turns. That combination makes it one of Klim’s most versatile pieces of adventure gear to date.
