Background – I have been camping for a little over 5 years now, mostly car camping. I have recently begun backpacking, and I am constantly adding new gear to my “collection” in an effort to get my gear list tailored more towards backpacking, specifically lightweight backpacking. Most of my backpacking trips are short duration, not more than one or two nights. I am planning some longer trips in the near future.

Field Information
Locations and Conditions Used
The Horse Thief has been used in locations throughout north Florida, for a total of approximately 20 trail nights. Weather conditions during my use have ranged from lows of 30 F (-1 C) to a high of 90 F (32 C), with humidity levels from 20% to 100% and precipitation from none to a torrential downpour. I have used the Horse Thief exclusively in a Hennessy Hammock, both with no pad under the bag and using a simple closed-cell foam pad trimmed to fit the pad sleeve of the bag.

Product Summary
The Horse Thief is a 35 F (2 C) rated 725 fill goose down mummy sleeping bag. Big Agnes uses a unique system for their bags in that there is no insulation on the bottom of the bag. Instead, there is a sleeve designed to be used with a mummy-shaped sleeping pad. While Big Agnes does recommend their own pads for use in the bag (and what manufacturer wouldn't) they do say that any mummy pad can be used. The pad sleeve measures 21.25 in (54 cm) at its widest point and tapers to 12 in (30.5 cm) at the foot of the bag, and is the full length of the bag. The sleeve itself is stitched around the perimeter of the sleeve to the edges of the top section of the bag or the zipper, depending on the section of the bag the sleeve adjoins. According to Big Agnes, the Horse Thief is constructed of "WRM-breathable, water resistant and wind proof microfiber ripstop" for both the inner and outer.

This bag is a series of 13 sections, each of which contains a separate quantity of down. These sections cover the top of the bag, and a small distance around the sides to the bottom of the bag, ending at the sides of the pad sleeve. The sections are divided by sections of fabric stitched to both the inner and outer fabric, forming a series of "tubes". There is a small Big Agnes logo on the top of the bag, centered on the second baffle from the neck.

The Horse Thief does not have a hood, but does have a pocket attached to the head end. This is for using either the Big Agnes Air Core pillow, or for stuffing clothing into for use as a pillow. There is a draft collar around the neck area of the bag, which is also down-filled. A drawstring cord runs through the edge of the neck section, with a cordlock to hold the cord when it has been cinched down.

The Horse Thief is available in two sizes, regular and long, and in either right or left zip. The zipper is 54 in (137 cm) long and follows the curve of the bag. There is a pull at both the top and bottom of the zipper. The bottom zipper pull allows for ventilation while keeping the bag zipped up. At the top of the zipper is a small flap attached with a hook and loop fastener that covers the zipper. I use this to help keep the zipper in position while tossing and turning at night. The zipper is attached to the filled section of the bag on one side, and to the pad sleeve on the other side. There is no anti-snag mechanism along the zipper, and I have experienced some snagging of the zipper but no ripping of the fabric as a result of these snags.

The pad sleeve is simply an extra layer of the same fabric the bag is constructed of and attached to the bottom of the bag, covering the full length of the bag. There is an opening 13 in (33 cm) from the head end of the bag with a flap sealed by a hook and loop patch for inserting a sleeping pad into the sleeve, and an opening near the foot end to allow me access to pull the bottom of the pad down. There is also a small opening in the sleeve on both sides at the head end to allow the inflation valve of a Big Agnes sleeping pad to be accessed while I am laying in the bag. Big Agnes also advertises with their sleeping pads that the pad can be left in the pad sleeve and the entire unit placed into the stuff sack for ease of carrying. I do not yet have a Big Agnes pad, so I cannot verify that claim at this time.

The Horse Thief comes with two bags, a cotton storage bag and a nylon stuff sack. The cotton bag is used to store the Horse Thief in a uncompressed state between trips, and the nylon stuff sack is for compressing the bag during travels. In addition there are two small loops of webbing on the foot of the bag, used for storing the bag in a hanging position instead of in the cotton storage bag. Hanging has been my method of storage when not on the trail throughout my usage of the Horse Thief. The included stuff bag is a simple cylinder of nylon fabric with a drawstring closure and a cordlock similar to the one on the neck closure of the sleeping bag. There is a flap of fabric inside the opening that is used to cover the open end of the stuff bag after placing the sleeping bag inside. On the bottom of the stuff bag is a strap that I use to help hold the stuff bag when removing the sleeping bag from within.

Conclusions
The Horse Thief is my first foray into the world of down camping equipment. This required some adjustment in my methods due to the care needed to ensure a long life for the down, such as not leaving the bag compressed and being careful to not let the bag get too wet.

So far, the bag has held up well under use. I have accumulated approximately 20 trail nights in the time I have owned my Horse Thief, and it has just recently had any noticeable loss of feathers through the fabric (and very few at that). The Horse Thief appears to handle humidity well, with no noticeable difference in loft regardless of the humidity level. I have experienced minimal snagging of the fabric with the zipper, but I have not noticed any damage to the fabric from the zipper snags.

The Horse Thief has done a good job of handling surface dirt, with most of the dirt easy to brush off. The bag had recently begun to develop a body-type odor, which is most likely due to not using a separate liner with the bag. Following the directions from Big Agnes, I washed the Horse Thief in a front-loading washing machine, and dried the bag in a dryer set on air dry. I used a detergent designed for delicate fabrics, and also took a hint from several other users of down products and placed a tennis ball in the dryer with the bag to "beat" the down clumps apart. This appears to have worked, as I had minimal issues after washing with any clumping of the down in the bag. As best as I can tell, I have not lost any of the wind and water resistance as a result of washing the bag. I do make an extra effort to ensure the bag remains dry throughout my usage, so water resistance would be difficult at best for me to judge.

In my experiences, I tend to actually sleep within the rated ranges for most of the sleeping bags I have used, neither finding them warmer or cooler than the rated temperatures but usually right on for me. I find the Horse Thief to be a very comfortable bag within its rated temperature range. I do find it a bit too warm for the higher end of temperatures I camp in. However, at the higher temperatures (above about 85 F [29 C]) I tend to not use any sleeping bag at all. In early October of 2005, I used my Horse Thief on an overnight trip with a low of 82 F (28 C). I placed the Horse Thief in my hammock prior to retiring for the night, and climbed in to lay on top of the bag as it was not cold enough to get in the bag. Within 10 minutes of climbing into my hammock, I had to remove the bag due to becoming too warm. I feel this has shown me the upper comfort range for my use.

I have had the Horse Thief down to 30 F (-1 C) during April of 2005 in Suwanee, Florida. This again was in my Hennessy Hammock, and using a closed-cell foam pad beneath the bag but not in the pad sleeve. I wore mid-weight pants and shirt as a base layer, an Ex-Officio Give-N-Go Skivvy top, a synthetic t-shirt, wool hiking socks and a knit watch cap. I was quite comfortable with this setup, and actually had to remove my synthetic t-shirt during the night because I had gotten almost too warm for comfort. This is the coldest trip I have taken so far with the Horse Thief, and feel that I could continue using the bag in similar conditions. My only issue with this use is the lack of a hood system to help keep my head warm, which the watch cap does help with.

I feel given my build, the Horse Thief allows me room to roll from side to side. I tend to not spend the night in any one position and require room to roll back and forth. The girth of the Horse Thief is adequate for me to have this range of movement.

The Horse Thief has lofted well after removing it from the nylon stuff sack throughout my usage. Upon setting up camp, I take the bag out and place it into my hammock to let it loft before going to bed. This gives the bag a minimum of one hour to loft, and on most occasions two to three hours. This appears to be more than adequate time for the bag to loft up.

One issue with the functionality of the bag that I have encountered, and is totally my own fault, is having a right side zipper on the bag I have. This poses a problem for using the bag with my Hennessy Hammock, as I find a left zip bag makes for much easier entry into the bag with it placed in the hammock. I have found that I can still enter and exit the bag while having the bag in the hammock, it just requires a bit more maneuvering on my part to make this work. I would definitely pay more attention to the zip side if I had the opportunity to make this purchase again.

Overall, the Horse Thief appears well constructed. I have not noticed any "wandering" seams, and no loose threads. During my use, I have not experienced any threads coming loose. I have only had a small loss of feathers from the bag, less than six feathers total that I have noticed. The bag has retained its loft well, and has remained comfortable.

Pros and Cons
Pros
1. Personal temperature comfort range (low 80s F [27 C] to 30 F [-1 C])
2. Small compressed size
3. Light weight

Cons
1. The extra care down requires
2. Lack of insulation on the bottom (remedied with the use of a pad)
