This video illustrates the first stage of the bivyâs evolution into a more comfortable solo shelter with the addition of a mesh screen and collapsible poles to improve ventilation and keep the screen off the userâs face. This bivy has a Gore-Tex top to reduce moisture built-up in your sleeping bag from sweat.This is particularly important in winter when trapped sweat can significantly reduce the thermal efficiency of your bag. often use a bivy, but I chose the alternative to waterproof materials, which is a DWR type made of Momentum.

1 A simple wisdom tooth extraction (where the tooth is fully erupted from the gums and has simple roots) using a local anesthetic costs about $75-$200 per tooth, or $300-$800 to have all four wisdom teeth removed as simple, non-surgical extractions.
To extract a single wisdom tooth, depending on procedure complexity, tooth position and where you live in the country, insured people might pay from $300 to $600 on average per tooth, says Jay Friedman, a general dentist and consultant in Los Angeles who analyzed a survey of fees in 2013 from the American Dental Assn.
