Bounce-free marathon training

20 weeks of marathon training in this vest and it has never bounced once, even fully loaded. The 20oz flasks are easy to grab without breaking stride. Water-resistant fabric handled two surprise downpours. Highly recommend.

Great for long runs

Flasks are easy to refill at fountains and the vest stays snug. Storage is enough for phone, gels, and a light layer. Slight pressure on the shoulders after 15+ miles but nothing serious.

Trail ready

Took this on technical trail runs and it moved with me the whole time. Nothing jiggles, nothing chafes. The flasks hold way more than my old 14oz ones.

Good vest, stiff straps

Functionally it's great — no bounce, flasks are convenient. But the straps took several runs to soften up and were stiff against my collarbone at first. Fine now.

Excellent

Light, comfortable, no bounce. Exactly what I wanted.

Solid choice for race day

Wore this for a trail 50-miler and it performed well. Both flasks stayed accessible and the front pockets made fueling automatic. The vest is genuinely lightweight even loaded down. Wish it came in more colors, but that's cosmetic.

Best vest under $100

Compared against vests twice this price and this one wins. The water-resistant fabric is a nice bonus for dewy morning runs. Reflective 360 visibility keeps me visible before dawn. My husband bought one too after seeing mine.

Very pleased

Comfortable from the first run, which is rare. Flasks don't slosh and pockets are well placed. Runs slightly small in the chest, so check the size chart.

Flask valve trouble

The vest itself is well made, but one flask's valve wouldn't stop dripping. Wasted half my water on a hot day. Reaching out to Nathan for a replacement flask.

Marathon race day hero

Ran a road marathon with this and aid station stops were instant — just squeeze the flask and go. Zero bounce across 26.2 miles is not an exaggeration. The fit over my race kit was snug and chafe-free. At this discount it's a no-brainer for anyone training seriously.
