Hyperlite Mountain Gear Aero 28 vs Hyperlite Mountain Gear Vertex 32
Quick take: The Hyperlite Mountain Gear Vertex 32 carries more (32 vs 28 liters); the Hyperlite Mountain Gear Aero 28 is lighter (1.1 vs 1.4 lbs).
Which one to buy
Pace and rock separate two Hyperlite packs that otherwise match: both cost $350, both are rated to 25 lb and both come in the same three torso sizes, S 15-17, M 17-19 and L 19-21 in, so measure your torso and the fit question is settled either way. What differs is the harness and the fabric.
The Aero 28 sits on a running-vest harness that keeps bottles and snacks on your chest, with 8.5 L of external pockets on top of its 28 L. It is 0.3 lb lighter, built from DCH 3.8, Hyperlite's thinnest and least abrasion-resistant laminate. That makes it a fastpacking and long-run pack, and a poor one to drag up granite.
The Vertex 32 is the climbing-day pack: Dyneema Woven Composite 5.0 on the body, a conventional strap set, and a removable foam back panel that doubles as a sit pad. It holds 4 L more inside and takes rock contact far better. If you move at a walk on rough ground, the Vertex is the better buy.
Hyperlite Mountain Gear Aero 28
For fastpackers and long trail runs where reaching bottles on the move matters more than abrasion resistance.
Hyperlite Mountain Gear Vertex 32
Best if your days involve scrambles, alpine rock or bushwhacking, where the woven body and foam panel earn their extra 0.3 lb.

Pros & cons
Hyperlite Mountain Gear Aero 28
- ✓A vest-style harness keeps bottles and snacks on the chest, where a runner can reach them.
- ✓8.5 L of external pocket space is a lot for a 28 L pack.
- ✓Under 18 oz in Medium for a fully laminate body.
- ✓Three sizes rather than the stretch-to-fit sizing common on vest packs.
- ✓Roll-top closure lets the volume shrink for shorter outings.
- ✓Rated to 25 lbs, enough for a light overnight kit.
- ✗$350 matches the Vertex 32 for less internal volume.
- ✗DCH 3.8 is the thinnest HMG laminate and the least abrasion-resistant.
- ✗No frame or back panel listed, so load shape depends on packing.
- ✗A vest harness can feel hot compared with a conventional strap set.
Hyperlite Mountain Gear Vertex 32
- ✓Dyneema Woven Composite 5.0 resists abrasion better than the plain laminates on HMG's trail daypacks.
- ✓Three torso sizes, which few 32 L daypacks offer.
- ✓The foam back panel comes out to serve as a sit pad or to cut weight.
- ✓25 lb rating is enough for a full day of alpine layers, rope and water.
- ✓22.4 oz is light for a pack with a woven-face body.
- ✗$350 is steep for a frameless 32 L pack.
- ✗No frame, so heavier loads ride entirely on the foam panel and straps.
- ✗Heavier and $140 pricier than the HMG Summit 30 for hikers who do not need the woven fabric.
Hyperlite Mountain Gear Aero 28 vs Hyperlite Mountain Gear Vertex 32: common questions
Will the Aero 28's thin laminate survive scrambling?▾
It is the wrong fabric for it. DCH 3.8 is Hyperlite's thinnest laminate and the least abrasion-resistant, with 100D Dyneema ripstop only at the wear points. The Vertex 32's woven DW 5.0 body is built for rock contact.
Can the Vertex 32 work for running?▾
It can carry the load, but it uses a conventional strap set rather than a vest, so bottles and snacks are not on your chest and the pack will move more at pace. The Aero 28 is the one designed for running.
Is either pack enough for an overnight?▾
Both are rated to 25 lb, enough for a light overnight kit. The Aero adds 8.5 L of external pockets for a fastpacking setup, while the Vertex's removable foam panel gives some structure to a frameless load.
