starting to border on not ultralight, but i have had need to keep water from freezing on long day rides in the shoulder season and in the middle of winter. and planning to do an overnight this year if i can upgrade a few pieces of gear...

these will fit into anything cages (which are great, BTW, if you don't overload them) on the pugsley or the fargo. pugsley if we get good snow, fargo if its cold and icy and i run studs.


Granite Gear bottle snugglies by mbeganyi, on Flickr\

granite gear aquasack - fit a nalgene into a sleeve with some bubble insulation. might not be workable below 0dF, but should work in the mid teens to 30s. will probably have to get something like the aquatherm or move to the outdoor research water bottle parka.
