I bought this bag for its weight and temp. rating…

Rating: rated 4 of 5 stars
Design: Mummy
Fill: polarguard 3D
Temperature Rating: 25� F
Weight: 2lbs 6oz
Price Paid: $79.99

I bought this bag for its weight and temp. rating at this price-point. The bag is very light and compresses down to 8" x 9" with a compression sack, perfect for backpacking. Inner lining is very comfortable and zippers are of good quality.

My only gripe (and it's kind of a biggy) is that this IS NOT a 25 degree bag. I tend to sleep warm and spending a night at freezing temp. in this bag was not comfortable at all. Finally ended up in full long underwear, a light fleece pullover, and doubling up on socks.

If you're looking for a light ~35 degree bag that compresses well at under $100, this is a good buy. If you're looking for something to keep you warm in cold temperatures, and think you might be able to make do with a 25 degree bag, keep looking. A 25 degree bag this aint!

Rating: rated 3 of 5 stars
Design: regular
Temperature Rating: 25
Price Paid: $55

Bought this bag for my 12-yr-old Boy Scout. It compresses very well, fits easily into the sleeping bag compartment on his backpack. The color is ugly enough that he thinks it's real cool.

Not sure what happened @ Kelty, but we thought we were getting a mummy bag and opened the box to find a square bottom. The color and tags are all the same as the mummy bag.

The only thing to be aware of is that when Kelty says regular size, they mean 5'9" or shorter. Any taller and you'll kick out the bottom. And a temp rating of 25 is closer to 40. My son has ended up sleeping in full fleece when the temp drops below 40 in the midwest.

Overall a very good bag for a 12-yr-old Boy Scout.

Retailers' Descriptions

Here's what other sites are saying:

For most of us, Kelty's Light Year 3D 25 is all the sleeping bag that's required for three-season camping, climbing and backpacking. It's an affordable, well-designed, easy-care bag that offers high-end features like a differential cut and ground-level side seams to minimize cold spots and heat loss on frosty nights. The Light Year 3D 25 also has a practical zippered foot vent that makes it easy to cool your toes throughout the warm early hours on a summer evening. The Light Year 3D 25 is easy to clean and repeated washings won't compromise the insulating properties of the Polarguard 3D synthetic fill. It even comes with hang loops for drying. One thing to consider is that Kelty reduced the weight of this highly compressible sleeping bag by extending the side zipper only to the hip. Backpackers and campers who require more cooling might need a slightly heavier bag with a full length zipper--if so, check out the 20F rated Mistral sleeping bag.

FREE Shipping on orders over $50. 1-800-986-0656 The Light Year 3D is a great down-alternative sleeping bag for 3 season camping and backpacking.

- refers to the men's version

The Kelty Men's Lightyear 3D sleeping bag is an easy-care synthetic bag that's perfect for wetter climates. The Lightyear 3D uses two-layer, offset quilt construction to help trap heat more efficiently and ensure uniform coverage of insulation. Polarguard 3D is not too heavy, packs well, and retains most of its heat even when soaked through. A draft tube runs the entire length of the Lightyear's zipper. In a particularly clever move, Kelty put the Lightyear's side seams at ground level, which means the seams aren't sitting against your body. Loops to tie on a sleeping pad and a zippered foot vent let you get maximum comfort and therefore maximum sleep out of your Lightyear.

Comes with a stuff sack and large storage bag. Differentiated drawcords allow quick identification, even in the dark so neck or hood adjustments are a cinch! Ground-level side seams keep warm air from escaping. Highly durable Polarguard 3D is lightweight, compressible, retains little moisture and continues to insulate even if wet. Locking 3/4-length zipper and zippered foot vent provide ventilation options. Made with a diamond ripstop nylon/polyester shell and soft polyester taffeta lining. Pad loops provide attachment points to keep your sleeping bag and pad together to avoid rolling off onto the cold ground (straps sold separately). The '06 Backpacker Magazine Gear Guide called this a "...dirt-tough 3-season workhorse during months of overnight treks and trailhead campouts.".

- REI refers to the men's version

The Kelty Light Year 25 sleeping bag with Polarguard 3D fill is an easy-care synthetic version of the light and fast Light Year bags. Draft Prevention Insulation tubes are placed along the zipper and at the neck area to prevent heat from escaping. In colder weather bags, the baffle collar can be drawn in to customize the fit. A two-way zipper can be opened from either the top or bottom. When the zipper reaches the end of its track and is fully closed, it locks into place and is prevented from pulling open. vWe all know that heat rises. By placing the side seams at ground-level, they ensure that more heat will stay in the bag. An expanded, three-dimensional area created by inserting fabric between the top and bottom layers at the end of the bag. It provides extra footroom and additional comfort.
