The SUL Waterbear has the same warm air tunnel around the face as the regular Waterbear, but the body is built more like a fitted jacket hood. Instead of pulling it over your head, it has two front snaps to secure it on and the tunnel has a tie drawcord. It fits more snug and moves with your head while active during the day. As the name suggests, it’s also lighter. Coming in at 1.5 ounces, it’s similar in weight to a many hats, but significantly warmer, covering more surface. The front snaps can be used for extra ventilation. It can be worn in a myriad of ways. Cinched closed, open tunnel, folded in tunnel, folded tunnel over mouth, one snap, wide open, even as a hat.
Approximate weight – 1.5oz
Ever have trouble sleeping because you’re breathing cold air, even though your body is toasty warm in a sleeping bag? This hood utilizes climashield and mesh to create a super breathable tunnel around your face so that there is always a pocket that warms the air before you breathe it. The opening is adjustable so that you can adjust the rate of air exchange and even fold it back in if needed. The climashield/mesh is so breathable that you can even close it down and breathe right through it. Climashield is exceptional at dealing with moisture so that condensation from your breath will not cause the batting to lose loft. In the morning you just shake it out and it dries super fast. The body is also built with 2.5oz/yd Climashield with a mesh inner shell for excellent moisture mitigation and a very breathable Argon 67 outer shell.
The Waterbear can be used as head insulation during the day as well, providing an opportunity to lighten your load by using one piece of gear for two purposes. For ultimate modular adjustment bring a light Waterbear and a hat. This way you can adjust for different temperatures on the fly. For instance, hood/hat on cold nights and just the hat when active on cool days. For further explanation on non-integrated hoods see http://www.timmermade.com/non-integrated-hood-sleep-systems.html
Comfortable low temperature range is estimated at 20 – 30f without a hat, below with a hat. How much lower is dependent on the hat used.
