Leatt – ADV 3.5 Thermaflow Jacket
The Leatt ADV 3.5 Thermaflow Jacket is made for riders who want a warm, breathable layer that works on cool trail mornings, windy climbs, or crisp evenings on and off the bike. It uses Thermaflow insulation that traps heat without feeling bulky, and the shell helps block wind and light moisture so you stay comfortable as conditions shift. The cut is designed for active movement, whether you’re pedaling technical climbs or cruising fire roads and it layers easily under a shell or over a base layer.
Reinforced panels in key zones help the jacket hold up to real world use, and integrated vents let air circulate when you’re working hard. It’s not a heavy winter coat, but it gives you more warmth and protection than a standard fleece without weighing you down.
Why We Like It
It strikes the right balance of warmth and mobility. You feel the difference when temps drop, but you don’t feel restricted or overheated when the pace gets going. The fit and construction make it easy to wear all day.
Why It’ll Work for You
If you want a jacket that keeps you warm without turning into a sauna or a thick bulky layer, this one fits the bill. The insulated core helps trap heat where you need it, while the wind-blocking shell stops cold air from cutting through. Vents help keep airflow moving when you’re climbing or working harder, and the overall cut moves with you so you’re not fighting the jacket when you’re standing, leaning, or reaching for grips. It’s comfortable, practical, and versatile for changing trail conditions.
