What Our Gearhead(R) Experts Are Saying:"This has become my go-to for travel days since it doesn't wrinkle and layers so easily under a jacket. The thumbhole cuffs are a small detail that makes a huge difference when the plane gets cold."There's a reason the Rib Knit Long-Sleeve Henley from Backcountry ends up on every packing list. It's the shirt you throw on before coffee and never bother changing out of, soft against the skin and easy to dress up or down as the day shifts. The four-button placket and thumbhole cuffs mean you're always one small adjustment away from just right.
