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. For me a bivy is to protect my down quilt from spindrift rain or snow, usually while under a minimal sized tarp.
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.
Many dentists or oral surgeons offer a package deal for extracting all four wisdom teeth at once. In lower-cost regions the total for four extractions plus sedation can be $1,000-$1,650, but nationwide the average cost for removing four wisdom teeth using general anesthetic runs around $1,500-$2,300, and it can be $2,500-$3,000 for extremely complex cases in high-cost regions, with oral surgeons typically charging higher fees than general dentists.
