Bambool BT1 Baselayer Top & Pants

Feel

The best blended-fabric baselayers cherry-pick the component materials’ strengths and offset their weaknesses—and that’s exactly the case with these 68-percent bamboo/27-percent merino/5-percent elastane layers. You get the soft feel and quick-dry magic of bamboo, plus the odor control and warm-when-wet properties of wool. “They don’t feel plasticky or prickly when your skin heats up,” says a tester.

Boot-friendly

The mid-calf bottoms don’t bunch with socks.
