Sleeping bag expander-- for big people
I just came across a device made for / by Big Agnes they call a "Wedgie."
Comes in two lengths for two typical sleeping bag (sb) zipper lengths.
Simple, but too damned expensive: A 50"-60" V shaped down-filled draft tube with zipper halves that mate to the zipper halves on the sb .
I just mistakenly bought a fine 20 degree bag......for some narrower people. I intend to use it as top quilt. 59" at shoulders should be plenty / too much width in a hammock. But for other uses of the bag, this expander might be the ticket to make a trade unnecessary.
Any experience here? Are sb zipper's standard enough so one or 2 products would be compatible across bag mfgs?
I wonder if there might be enough demand for one of the cottage industries to make a product with same function. Or knowledge to tell me not to bother even trying one.
Once free to move in a hammock w top quilt
I lost interest in expanding the bag. I see that Western Mountaineering recognizes that some would their mummy bags be larger, so a couple of their models are larger twins of previous ones.
Related to this thread is my TQ for a chilly but rarely freezing November in Oregon. I opened the back of one of the RAB top bags that was discussed here -- a sleeping bag with just fabric on the bottom except for a fully enclosed and insulated foot box. Expectation is that the user would like in a pad and his body. Or just his body, and then lay on a pad. I, instead, slit and sealed the fabric to just below the neck, leaving an intact collar. I can then step into the footbox, pull the collar around my neck, to keep the the bag / quilt over me, and yet have freedom of movement between and neck and knees.
