Sea To Summit Watercell X Review: Ultimate Water Storage Option

When camping, bikepacking, or backpacking, proper water storage can make or break your experience.

When trekking out into the backcountry, one of the most important (if not the most important) factors to consider is hydration. Whether you're planning on an extended kayaking trip, a camping excursion, or a several-week expedition, there aren't enough water bottles to make it through the whole thing, which is why the Sea To Summit Watercell X is a must-have piece of camping gear.

If you're a camper and you're tired of using those massive multi-gallon jugs as your water supply when you go off the grid, the Watercell X can hold between 6 and 20 liters, depending on what capacity you select. Water storage is as necessary as sleeping bags and sleeping pads when you're planning for multiple days in the wilderness, which is why it's a great idea to have a quality, easy-to-carry water bag in your camping gear.

The Sea to Summit Watercell X is a lightweight camping water storage bag and dispenser for backpacking, camping, bikepacking, paddle sports, expeditions, and adventure travel. It's effortless to carry with you when empty as it rolls into small sizes, which is way more convenient than other water storage systems.

Its 3D molded shape features an internal baffle for easier filling, packing, draining, and drying. The Watercell X is made from abrasion-resistant, semi-translucent, food-grade TPU, with RF welded seams. An adjustable webbing strap and strong, streamlined grab-handles make it easy to hang, carry, or attach the bag anywhere, while a low-profile fill-handle provides one-handed manageability. The adjustable strap makes it easy to hang this water bladder anywhere so that you can get the best use out of it.

Whether you use it to clean your cookware, take a shower, or fill up your water bottles, the welded lash points ensure it stays put anywhere you hang it.

The screw-top wide-mouth opening is compatible with most industry-standard water filters and replacement lids; the multi-function dispenser cap features flow control and includes a shower head attachment for easy bathing during backcountry excursions. The Watercell X has a solid RF-welded 3D shape with an internal baffle that allows for easy use and compact packing.

The Sea to Summit Watercell X is available in four sizes: a four-liter, a six-liter, a ten-liter, and a 20-liter option. All are BPA-free, PVC-free, and taste-free. I tested the 20-liter option and used it for a single-night camping trip. In Arizona, water storage is a big concern, even if you're only camping for a night or going for a long day hike.

Anyone who is also dealing with the issue of carrying enough water during long hikes should consider adding this to their shopping cart or wish list! Sea to Summit has a flexible return policy, too, as long as you return it with original tags and within 30 days of purchase, so if you find you want a larger water liner exchanging it would be no issue.

If you're looking for something a little less heavy-duty, the Sea To Summit Watercell St is perfect for lighter activities, like days at the beach or other lightweight excursions. This water storage bag works well if you have access to water and want a little extra convenience, like water to cook with over the stove. It would work well for motorcycle camping or snow sports, too, as it's ultralight and easy to carry if you need some extra water to take skiing for the day or something similar.

Sea to Summit products are guaranteed against defects in materials or craft for the lifetime of the product. I love when companies take the quality of their products so seriously. Even if it breaks or has a severe defect, you can exchange it for a new one without any of the hassles that sometimes come with trying to get a replacement product.

I highly recommend the Sea to Summit Watercell X to anyone who loves backpacking, camping, or day hikes. It's a fantastic water storage solution with a ton of different uses, whether you use it for drinking water, to take showers while you're out in the backcountry, to cook food over your camp stove, or for any other need you may have.
