Or, I've skipped the head gap and just kind of tucked it someplace about my neck.

Using a gentle layer of artificial long underwear, then a light-weight rain go well with, accompanied by large fleece my summer time pounds down undesirable provided greater than sufficient insulation to maintain toasty warm at zero levels.

Trouter on February 3, 2016 at 10:53 pm Andrew, thanks with the in-depth clarification on the VBL approach.
