A good choice for dependable fast-and-light warmth.


  • Lightweight
  • Accurate comfort rating
  • Sheds water


  • Dri-down is a little clammy
  • Could use a higher fill-power down
  • Cost

This is a well-designed sleeping bad. The hood, draft collar, and overall fit are great.  The bag is a little roomier tan a typical mummy. This is nice for three-season sleeping, but on cold nights (below freezing) the extra space reduces the efficiency of the bag somewhat.  

The Dri-down works as advertised, with a shorter dry time than normal down. The bag's DWR coating also sheds light moisture very well. Given these attributes, I was not surprised to find that the Dri-down bag is a little clammy as compared to my normal down bags.  

It seems that the DWR coating on the shell, combined with the Dri-down treatment, can actually trap a little moisture in the bag. In particular, I noticed dampness around my feet (and cold feet as a result).  This was easily fixed by wearing socks to absorb sweat and reduce moisture in the bag. Compression is great - I can get the "long" version down to something smaller than a water bottle.

One nice feature: the "short" and "long" versions have opposite-side zippers. This means my wife and I can easily zip our bags together (for warmth, of course). The advertised as a full-length zipper, but in reality they use the same zipper for all three lengths, so the zipper on the long version runs about 80% down the bag.  But this is fine, and entry/exit are easy.

Nits include a scratchy piece of Velcro near the hood, and a tiny zipper pull that can be hard t find at night. I also wish this bag used 900 fill down (and weighed 4-6 ounces less) or cost about $100 less. $350 seems a little high for a 750 power down bag.  

The bag is true to its rating. I was comfortable on nights in the 25-60 degree range. With a long underwear top and bottom, it works very well down to about 15 degrees.  Above 60 degrees you can open the bag into a quilt and use only part of it to avoid roasting.  

Overall this is a solid performer that has replaced my synthetic 3-season bag for general use.

Retailers' Descriptions

Here's what other sites are saying:

The Sea to Summit Talus series boasts many of the features seen in higher priced bags and is ideal for a wide range of activities offering comfort, warmth, and moisture shedding capability.The hood is designed to cocoon your head completely in a way that maximizes the available loft without making it feel claustrophobic. There is an adjustable collar to help fine-tune the warmth and seal out drafts. The drawcord channel in the collar and hood are buried deep within the down so there are no annoying harsh edges to push into your neck or face. The discreet zippered pocket is perfect for your MP3 player or valuables, and the main zipper (which can be joined to other Sea to Summit bags) has an anti-snag system that really works!The cut of the bag and baffles are engineered to prevent down shift and allow the down to reach its maximum loft (and therefore its maximum insulation value) simple in theory but complex to execute. It involves using differentially cut, three dimensional side-walls and curved baffles.The Talus features an improved 2D NanoShell outer shell fabric, specially engineered for breathability (Moisture Vapor Transmission Rate: 7500 g/m2/24hr) and excellent water repellency (1000mm). This helps ensure that external moisture (such as condensation on the inner wall of a tent) doesnt dampen your bag or your enthusiasm for venturing into the backcountry.The Talus series is your choice for nearly any adventure in all but the most extreme climates.

The breathable Nylon 2D NanoShell wicks more moisture away from your body for increased comfort. Twenty-denier, soft-touch polyester lining.
