Hydration on-the-go with DolfinPack! This minimalist hydration pack sets itself apart from other hydration packs on the market by being form fitting and non-restrictive for those active adventures. A patent-pending three-way adjustable strap system, one across the chest and one on each shoulder, ensure that the pack will stay put, reducing the risk of chaffing or irritation. It’s completely covered with a durable, easy-to-clean, neoprene, even the straps and the hose cover, which also helps to keep the water cool. The hydration bladder is a good size at 1.5 liters and has a nice big, leak-proof opening, making it easy to fill and clean. Smartly, they’ve included 5 drainage holes at the base of the pack so that when you take this little guy out on the water or maybe even through the mud and muck, if you’re into obstacle racing, it drains out and you won’t be weighted down. The minimalist nature of the pack means that it only weighs 5.6 ounces, yet there’s still enough room to sneak in a zip lock bag with a key or two plus ID and money in the main compartment. DolfinPack is a lightweight, comfortable hydration pack for all your TrailblazerGirl activities!
