Leatt – ADV 5.5 Thermaflow Mid Layer Jacket
The ADV 5.5 Thermaflow Mid Layer is built for adventure riding when you need warmth without stacking bulky layers. It’s slim, flexible, and easy to wear under riding gear, but comfortable enough to throw on around camp when the temperature drops. The jacket uses a wind-blocking softshell paired with graphene-infused insulation and a 3D fleece backing to manage heat more evenly instead of trapping it in one spot. That helps keep your body temperature steady as conditions change throughout the day.
Durability is handled where it matters most, with reinforced elbows and seat areas using lightweight stretch ripstop. A DWR C0/20 eco-friendly water-repellent treatment helps shed light moisture and dirt, while the 4-way stretch construction keeps movement natural on and off the bike. Inside, taped seams and a smooth finish prevent irritation during long days in the saddle, and secure YKK-zippered pockets keep small essentials in place.
Why We Like It
It adds warmth without feeling bulky or restrictive. The jacket layers cleanly under riding gear, blocks wind well, and spreads heat evenly so you don’t get hot spots or cold patches. It feels purpose-built for ADV riding, not just a generic insulated layer.
Why It’ll Work for You
This mid layer is designed to keep you warm while staying low-profile and flexible. The graphene insulation redistributes heat across the jacket, helping maintain a more consistent temperature as you ride. The wind-blocking shell cuts cold air, and the stretch fabric lets you move freely when standing, sitting, or walking around camp. Reinforced areas add durability for long-term use, and the water-repellent finish helps handle light weather without needing an extra layer. It’s easy to wear, easy to layer, and comfortable for all-day ADV riding.
