Why You’ll Love It

  • Collapses completely flat  Fits in a pocket when empty.

  • 500ml capacity  Enough for a hike, a run, or a day out.

  • BPA-free food-safe material  Safe to drink from, every time.

  • Lightweight  You won't notice it in your bag until you need it.

  • Leak-proof when sealed  No surprises at the bottom of your pack.

 

Description

The water bottle that actually packs away. When you're done, it folds completely flat and slides into a pocket no awkward bulge, no rattling around in your bag. When you need it, it opens up and holds 500ml without leaking.

BPA-free, food-safe, and lightweight enough that bringing it along is a no-brainer. Throw one in your day pack and forget about it until you need a refill.

No-bounce fit is the real deal.

Took this on a 4-hour trail run and it doesn't shift even on technical downhill. Pockets fit my phone, gels, and keys without any bulk.

Thumb loops are a game changer.

Full coverage without having to think about it. Wore it fishing all day — no burn, no complaints. Full coverage without having to think about it. Wore it fishing all day — no burn, no complaints. Full coverage without having to think about it. Wore it fishing all day — no burn, no complaints.

Looks good on and off the trail.

I'm not a hardcore hiker just someone who walks a lot on weekends. This is the perfect throw it on and go layer. Lightweight, fits slim, doesn't look like gear.

Sip and keep moving.

I used to stop every 30 minutes to drink from my bag. Now I just sip and keep moving. The vest sits so close to my body I forget it's there. I used to stop every 30 minutes to drink from my bag.

Forgot sunscreen existed.

Wore it on a 3-hour coastal walk. The hood stays put, the fabric doesn't overheat, and I got zero tan lines. Already ordered one for my sister. Wore it on a 3-hour coastal walk.

First vest that doesn't fight me.

Been through 3 hydration vests and this is the first one that feels like it's working with me, not against me.

Dried within minutes on a steep climb.

Poured sweat on a steep climb and was dry within minutes of hitting the ridge. Quick-dry fabric is no joke. Poured sweat on a steep climb and was dry within minutes of hitting the ridge.

This is the zip top I've been looking for. Not too fitted, not baggy, moves with you everywhere. This is the zip top I've been looking for. Not too fitted, not baggy, moves with you everywhere. This is the zip top I've been looking for. Not too fitted, not baggy, moves with you everywhere.

Dried faster than I expected.

Activewear that doesn't look sloppy.

Finally an activewear top that looks put-together. Slim enough to look great, stretchy enough that nothing feels restricted. Finally an activewear top that looks put-together.

Great light, wish it had a dimmer.

Really happy with this. Bright, compact, easy to use. Only thing missing is a dimmer setting for when you just want a soft glow at night. Full brightness is a lot. But for the price, excellent.

The two-size set is perfectly thought out.

One cup for cooking, one for drinking. They nest perfectly and cover everything you need. No more packing multiple containers. This is the kind of simple, smart gear I love.

Small but incredibly bright.

Did not expect this much light from something this small. Hung it in the tent and it lit up the whole space. Battery lasts way longer than I expected too. Perfect camping light.
