The Black Diamond Pursuit Hybrid Pant reinforces the knees, seat, and cuffs- the high-use areas on climbing, backpacking, and peakbagging days. The reinforcement leaves the stretch and breathability intact, so the added durability does not stiffen these women's pants. What Our Gearhead(R) Experts Are Saying:"I step onto hip-high ledges on a scramble without the fabric binding at my thighs. The knees are cut to bend with the leg, and the gusset sewn into the inseam adds room for a high step."
