Night Eyes 311 vs Runoff: Two Waterproof Toiletry Pouches Compared
Two minimalist, fully waterproof toiletry pouches from Night Eyes, compared for capacity, packing style, and hanging options.
Introduction
Night Eyes makes a name for itself with innovative minimalist gear that works especially well for travel, and these two waterproof toiletry pouches fit that pattern well. Both are made from the same core materials: a TPU-impregnated fabric welded onto a TPU rubber-like plastic, with a clear front window so you can see what is inside without opening anything.
Both pouches are also genuinely light. The listed weight for the 311 is 2.4 ounces, and our scale reads even less at about 1.4 ounces. The Runoff toiletry bag lists at 2.8 ounces and weighs roughly 2.4 ounces on the same scale. If your kit needs to stay under about 3 ounces, both clear that bar comfortably.
The Standout Feature: A Truly Waterproof Zipper
Most waterproof bags rely on something like a YKK AquaGuard zipper, which works well by putting a seal on the outside of the bag. The catch is that these zippers still use nylon teeth, so the seal has to come together perfectly, and there is always a tiny gap where the zipper meets at the ends.
Night Eyes takes a different approach. The zipper is designed more like a ziplock bag, with thick rubber edges that overlap when you close the slider, and a soft rubber housing at the end that the zipper pull seats into. That makes a completely waterproof seal. In testing, the large pouch was filled completely full of water, roughly 3 liters and around 6.5 pounds, and it did not leak at all.

The one drawback of this design is feel: the zippers are a little stiff, and you need to apply a decent amount of pressure to open them and to seat them properly into the housing. It is a small trade-off for the level of waterproofing on offer.
Night Eyes 311: The TSA-Friendly Liquids Pouch
The 311 is designed as a TSA-compliant liquids pouch, with a capacity of about 1 liter, or roughly 1 quart. You can use it purely as your liquids bag, packed full of 3.4-ounce or smaller bottles, or, if you travel light enough, as your entire toiletry kit.
Hanging is where the 311 really shines. It has two reinforced clip points on either side plus two belt loops on the back, giving it four attachment points in total. You can run cord through the belt loops, tie into the clip points, or clip it up with small locks and string. If you want a pouch you can hang in the shower, this is the easier choice of the two.
Night Eyes Runoff: The Rectangular Dopp Kit
The Runoff toiletry bag is the larger sibling, shaped like a rectangular dopp kit with about 3 liters, or roughly 3 quarts, of capacity. The rectangular form means it packs a ton of gear and is genuinely easy to pack, with no sharp corners to waste volume.
The main limitation is hanging. It has a thick fabric loop on one end and a smaller clip point on the other, so one option is to hang it by the loop and leave the zipper about halfway open to reach your things. It works, but it is not ideal, since there is no way to hang the bag with the zipper facing up.

Packing Comparison: How Much Fits
Packed with a standard minimalist setup, a few larger bottles, basic toiletries, and a shampoo bar, the 311 fills up quickly. Because of its tapered seams at the sides and top, larger round bottles need a bit of Tetris to fit properly, and you lose a little usable capacity to those corners.
The Runoff, at roughly 3 to 3.5 liters, is easily three times the size. In testing, an entire collection of toiletries was packed in with room to spare, more than most people would ever take on the road, and the wide rectangular opening means you can essentially just drop everything in.

The sheer size also opens it up to non-toiletry uses. A travel towel or other small items you want to keep dry fit comfortably, and at only about an ounce more weight than the 311, the extra capacity comes cheap.
Which One Should You Buy?
If you are on the fence, the choice comes down to packing style and size. The 311 forces you to pack quite a bit smaller than you may be used to, and its tapered corners cost a little capacity. In exchange, it is far more versatile for hanging, with four attachment points that also open up a second life as a small dry bag: empty out the toiletries, load in electronics, and hook it to a belt while hiking or paddleboarding.

The Runoff is the better pick if you want generous, easy packing volume and do not need to hang the bag in the shower. Ideally, a future iteration would combine the best of both: a Runoff around half the size, maybe 1.5 liters, or a 311 with corner gussets to make it more rectangular and easier to pack.
Conclusion
Both Night Eyes pouches are extremely well made, rugged, and genuinely waterproof thanks to the ziplock-style sealing zipper. The materials are essentially identical, so the decision is really about size and style: the 311 for travelers who want a compact, hang-anywhere liquids pouch or dry bag, and the Runoff for those who want maximum, fuss-free capacity in a rectangular dopp kit form.
