What our reviewers liked and didn't
Men's Sawtooth Shirt
- Single-origin 100% Montana merino wool sourced directly from open-range ranches
- Naturally resists ember sparks, odors, wind, and light mountain precipitation
- Retains warmth effectively even when soaked through by sweat or melted snow
- Significantly softer next-to-skin feel than legacy scratchy wool shirts
- Requires careful hand-washing or dry-cleaning to prevent severe shrinkage
- Heavier and less compressible than technical synthetic midlayers
- Premium domestic manufacturing carries a substantial initial price tag
Men's Plaid Board Shirt
- Pure virgin wool insulates reliably even when thoroughly damp
- Naturally resistant to campfire sparks and flying embers
- Machine washable wool eliminates routine dry cleaning hassles
- Dense weave provides far better wind resistance than cotton flannel
- Untreated wool texture can feel prickly against bare skin
- Generous vintage cut can feel excessively boxy on slender frames
- Bulky to roll and pack away in a standard backcountry pack
