Mobility

The Psiphon’s generous stretch (85 percent nylon for durability and 15 percent elastane) let us reach and twist with no binding in the arms and shoulders. Bonus: Small foam inserts on the hem physically block the shell from pulling out of a harness.

Breathability

Superb. We never overheated, even while climbing 5.10 on Arizona’s Mt. Lemmon in 60°F temps or while hiking a loop in Colorado’s Golden Gate State Park that was so hilly and steep we passed mountain bikers pushing their rides.

Features

Testers loved the single-pull-adjustable, ultralight nylon hood, which fit nicely both under and over a climbing helmet. Kudos also went to the gusseted elastic cuffs, which cling closely to the wrist.

Protection

It adds breathable cover in gusty weather from the low 30s to low 70s, but it’s definitely not a hardshell. If it rains, you need more.

Fit

The very slim cut made this shell somewhat difficult to pull on and off despite a long chest zip (testers said it felt comfortable once on). Consider going up a size if you prefer a looser fit.

Packability

The Psiphon smushes to softball size.
