What backpacking gear do you recommend for Colorado trails?—SophiaConcord, New Hampshire

I just got back from a backpacking trip and used my CelBak bladder in the pouch included in my backpack. I liked using this system instead of reaching back for a water bottle, but the bladder is hard to refill when buried in the pack and also takes up pack space. Is there another kind of bladder out there? Maybe a square one that can sit on top my gear, near the top of the pack? This would keep it out of the way and make it easy to access. Joseph Moraga, CA

I hike with a hydration bladder, but I have a couple of issues with the system. When hiking with my friends, I quickly run out of water much faster than they do. Plus, it’s very difficult to gauge how much water remains without pulling out the bladder and then reloading it. Also, when my pack is full, it requires a lot of effort to insert the full bladder. Do bladder-style hydration systems exist with a method to gauge how much water remains? Toby Brussels, Belgium

We never knew that the world needed another polycarbonate water bottle until we wrapped a hand around CamelBak’s 750ml splash-, spill-, and shatterproof beauty. The bottle mates ‘Bak’s bite valve with a plastic straw for no-head-tilt hydration. Just try to find an easier way to suck down agua in the…

I'm looking for a hydration pack with two bladders and a toggle switch to let me move back and forth from one to the other while cycling. Is there such a thing? Scott Corvallis, Montana

I pretty new to running and going to do a 13-mile trail run that is expected to take about four-plus hours. I looking for hydration packs as there will not be aid stations or anything like that. My concern is with the hydration backpacks or lumbar packs that offer only one place to store one kind of drink. What do I do about carrying water and my electrolyte replacement? Are backpacks out of the question? How do you feel about The North Face Dayhiker Lumbar Pack? It has plenty of room for food, and has a dual source for water and my other drink.
