Hyperlite Pemi 15 Field Test: Where Does It Fit in My Setup?

Hyperlite Mountain Gear Pemi 15, second outing. First time out, the pack soaked through. Hyperlite had a theory. Today’s 20K aerobic base run was the test. The Pemi 15 sits in a gap between my 12-liter vest for standard ultras and a 30-liter fastpack for overnights. If it works, it’s the right pack for the Great Range Traverse, a single-day Pemi Loop, or a Presidential Traverse. If it doesn’t, it’s an expensive lesson. There’s a distinction in waterproof gear that most reviews skip — the difference between rain resistance and high-output endurance use. One is tested in a downpour. The other isn’t tested at all. Today’s run answered the question. Stays in the rotation, or back in the box. Run data for context: 20K, 1 hour 49 minutes in zone 2, 1 minute 43 seconds above zone 2, averaging ~14:15/mi. Aerobic base work to balance a threshold-heavy week. Also testing a fueling shift — every 5K instead of every 10K, maple syrup in a flask.
