What the review rated highly

Fit. The vest rides high on the body, which the review credits for most of the quality of fit. Materials stretch in every direction and compress back down, so the vest stays close whether it is loaded or empty. Tightening is done with a rotary dial — turn clockwise to snug it — rather than by pulling and re-threading straps mid-run. Both chest straps are fully elasticated so breathing is unrestricted.

Expansion. The four-way stretch means each pocket takes considerably more than it looks like it should, and returns to a flat profile when empty. The front dump pockets are deep and stretchy enough to hold soft flasks or bottles in addition to the dedicated positions — an unexpectedly useful option when you want to carry more fluid than the vest was designed around.

The back. A single large interior pocket, divisible into three, with a water-resistant divider you can use or leave out. A velcro strap keeps a bladder from sliding down. Baffles let it expand without losing its shape. The rear kangaroo pocket is reachable from the front, assuming a degree of flexibility.

Storage overall. Judged close to spot-on for everything short of the most demanding mountain outings.

Pole storage. More options than the review had seen on any vest: Z-poles horizontally across the front using the shoulder elastics, or vertically on either side of the back.

What it wanted changed

Size range. Three sizes — XS, S/M and L/XL. At 6‘0” with a 38” chest the reviewer was almost exactly at the top of the range, which raises a real question about who the L/XL is actually for.

Fit at the back of the neck. The high ride creates a slightly odd fit across the middle of the upper back. It takes getting used to and would not bother everyone, but it is there.

Wasted shoulder-strap space. Four or five inches at the top of each shoulder strap does nothing. The review wanted small gel or salt pockets there, and it is hard to disagree.

Where it belongs

Mountain days, long ones, with poles. Not the vest for a fast 50k where you want the least possible fabric, but the one you want when the day is long enough that the dial and the pole options start earning their weight.
