Inov-8 Race Pro 18: Ultralight, frameless day hiking/cycling/running/adventure racing pack designed for a unique horizontal-position water bladder that sits around your hips instead of in the normal straight up-and-down position.
Hip-level hydration
Likes: Very comfortable. Using the optional bladder (which you must buy to make the horizontal format work), you barely feel the water weight. Very convenient waist-belt pockets for on-the-move access to energy bars. Includes 18-liter cargo bay with separate top mesh pocket for camera or other quick-access essentials. 16.5 ounces.
Dislikes: It takes a little extra time to carefully fit the bladder in place after you remove it for cleaning.
Price: $90. Bladder (sold separately), $25. (877) 88-INOV8; www.inov-8.us

The breeze at your back
Osprey Atmos 35: Mid-size day/overnight pack with unique ventilation, food access pockets and carrying capacity.
Likes: Innovative, practical, comfortable product. Your entire back stays cool against a huge mesh compartment that is created by an internal aluminum frame that props the cargo bay away from your skin.
The space is so huge you could throw valuables or another hydration bladder in it. Great air flow combines with well-balanced 35-liter carrying capacity. Includes massive, zippered, mesh waist-belt pockets big enough to hold fruit, plus a pocket for a hydration bladder (not included) and an access port, four gear loops, lateral stretch pockets for food and hiking poles, and a pair of tie-down straps for a sleeping bag. 2 pounds, 9 ounces.
Dislikes: None.
Price: $159. (970) 564-5900; www.ospreypacks.com
