Great backpack. Big pockets, very accessible. A good buy.

Well designed day pack with numerous pouches and ease of accessibility.
I own a Camelbak Mule, which has served well over the last 4 years but the ease of installing the bladder on the Alpine Explorer is a breeze even with the pack
nearly loaded.
I viewed a number of other day packs and this one suits my needs extremely well. The pack rides well and the wider
waist belt is also a great addition.

I recently purchased a CamelBak Alpine Explorer for use as a general purpose daypack. I looked at all of the major brands but kept coming back to the CamelBak. The pack is about 1800cu inches and includes a separate bladder pouch that does not interfere by taking up room in the main pack. The bladder zips into its own space that makes taking it in and out a breeze. The main pocket is quite large and there is ample room for all of your daily hiking needs. You can easily fit in a lightweight jacket and pants, as well as nearly any amount of food plus another bladder. There is an outside mesh pocket that is situated between the main pocket and a smaller, exterior pocket. This can be used for maps, guide books or your rain shell. The exterior pocket is large enough for a first aid kit, medium sized books and trail snacks. Near the top of the main pocket there is also a small zippered pocket that can be used to hold sunglasses, an MP3 or what I used it for, holding my digital camera. There are two cinch adjusters on each side as well as exterior bottle pockets.
The back is channeled for good airflow and also features an internal, frame sheet. The waist belt does what it should, but can not be stored out of the way.
This is a great pack that can and should be used for anything you do. I have so far used it to day hike Mt. Rainier, carry three kids' lunches during a field trip to the zoo for my son's class and use it as an airplane carry on for a short trip.

I am extremely pleased with the pack - it has lots of room and is very comfortable

This is an awesome backpack that is great for one-day ascents or trips. I just recently used it on a two week climbing trip, and it was perfect for bringing up to the cliffs each day. I was able to fit all my climbing gear in it, plus some food and extra clothing. There is also tons of water space between the pouch and the two water bottle holders. It also kept much of my gear dry when the weather got crappy, especially in the front pocket that has a waterproof zipper. Another cool feature is that there are no straps bouncing all around when you are hiking, because they can all be bound up by built in hook-and-loop strips. This is a great pack, and I strongly recommend it!

Pleased with the alpine explorer - really like the updated bite valve with cover and on/off valve. Straps allowing for expanding or compressing the pack depending on size of your load are also nice. Open storage section allows for quick access. Waist belt is comfortable. One nice thing would be to have a drinking tube clip like on other models.

This pack works great for day trips, biking, and winter trips up the mountain. Great fit and plenty of room for all your day-trip tools whether you're packing for bad weather or going backcountry. Reminds me of Dakine pack quality, that's a good thing. Little heavier than I'd like, but that what makes them last. Camelback is just bladders and bottles, they actually put together a decent pack.
