What Our Gearhead(R) Experts Are Saying:"I threw these on under my shell pants for a bootpack that turned into more of a workout than expected, and the perforated crotch gusset actually made a difference venting heat on the climb up. Once I dropped in, the fitted cut meant zero bunching under my outer layer."A base layer pant lives or dies on the details nobody sees, and the BlackStrap Skyliner Pulse Pant gets those details right. We think of a steep bootpack that turns into a sweat session, a quick change at the car, and a layer that never once needed adjusting in between. The fitted cut sits close without restricting, so it disappears under shell pants instead of adding bulk at the knee or waist. A perforated crotch gusset vents heat exactly where it builds up fastest, a functional fly means one less layer to peel back at the worst possible moment, and a brushed elastic waistband stays put through hikes, lift rides, and everything in between without ever needing a cinch or adjustment.
