Sleeping bags
Weights and prices come from Feathered Friends. Each product page was cross-checked against the store's collection page, but those are the same company, so this is not an independent check. No other seller or outside weigh-in turned up.
Fit rules
The crampon rules come from REI, Needle Sports and Climb On Equipment. The binding rules come from Switchback Travel, SKI Magazine and Glisshop. Glisshop's table lists ISO 5355 boots as working with traditional alpine bindings only. Switchback and an Atomic listing at Backcountry say multi-norm bindings take them too. That disagreement is noted on the binding page.
