The Albion Unisex PrimaLoft Active Evolve Body Warmer is an ultralight insulating layer designed to adapt to changing levels of effort. Worn on its own, it provides highly breathable warmth without trapping excess heat. Layered underneath a gilet or jacket, it adds extra insulation when conditions become colder.
PrimaLoft® Active Evolve combines warmth with exceptional air permeability, stretch, and moisture management. The soft fabric moves moisture away from the body during harder efforts while maintaining useful insulation when activity levels drop. At just 75 grams, the body warmer is highly packable and easy to carry throughout the ride.
Key features
Performance & construction
PrimaLoft® Active Evolve is designed to balance insulation, breathability, and moisture management across changing levels of activity. Its open construction allows excess heat and moisture to escape efficiently during harder efforts while adding warmth when layered beneath a protective outer shell.
The sleeveless construction makes it easy to integrate into a wider layering system without adding excessive bulk around the arms.
Technical specifications
Size & fit
Designed with a unisex fit. If between sizes, choose the smaller size for a closer fit or size up for additional room when layering underneath.
Care instructions
Follow the care label inside the garment. Wash technical garments gently and allow to dry fully before storing to help preserve the fabric’s shape and performance.

The ABR1 Pocket Bib Shorts are made for the longest days on the bike. Albion developed them with ultra-distance riders, and they've been ridden to wins and record times on the Tour Divide, the Atlas Mountain Race and the Highland Trail 550. If your rides are measured in hours rather than kilometres, start here.
Two mesh leg pockets and a rear side-entry pocket let you carry a phone, gels or a wind jacket without touching your jersey pockets. That's handy on gravel and bikepacking trips, and just as useful on a long road day. Everything stays reachable while you ride.
The Albion x Elastic Interface chamois is built for long hours in the saddle. The 2025 update adds a higher gauge main fabric for more compression and polypropylene-knit straps that move moisture away faster. A hidden Rear Guard panel above the pad makes the shorts last longer.
An on-bike fit that runs true to size, with a reduced number of panels and flatlock seams. Our studio model is 180 cm (chest 91 cm, inner leg 80 cm) and wears size S. Want to compare them with your current bibs? Try them on in one of our stores in Amsterdam, Utrecht or Rotterdam.
