When you’re working hard, you produce enough heat to go light on insulation. The TLT Hybrid gives hard chargers just the right amount, thanks to body mapping: It uses synthetic PrimaLoft Luxe in the shoulders, torso, and upper back, while woven nylon-elastane in the arms, sides, lower back, and hood dumps heat and boosts mobility. “I could pole plant unhindered, and the silicone-lined waistband kept the TLT Hybrid from riding up under my pack,” says one tester who used it for early morning skimo training in Colorado’s Front Range.
An uninsulated, scuba-style hood traps heat without getting too sweaty. It can fit beneath or over a helmet. The TLT Hybrid packs down to the size of a cantaloupe.
“Because it’s trim and fits under a shell, I kept it on during bouts of driving snow in 20°F weather and didn’t overheat,” said one mountaineer after five weeks in France’s Mont Blanc region.
