Known Concerns3 issues reported
Lightweight fabric is prone to pilling and snagging in dense brush or on rough rock. Newer production runs may pill more quickly than older versions.
No double-layer reinforcement at high-wear areas like cuffs and knees. Cuffs are particularly prone to scuffing and fraying with extended use.
Waistband can stretch out after consecutive days of wear. Low-hip sit position can be uncomfortable under a climbing harness.
