Hi Sherpadog! Great first post!

The weight of your pack is truly impressive! Are you able to keep this BOB from freezing? Things like power gels turn into solid ice and making eating them challenging in the winter.

Would you consider adding a bear-pepper-spray to the pack? In an emergency, you may need to travel silently and the last time I was in B.C. I remember seeing a few big bears that I wouldn't want to sneak up on. As a plus it can be used for other things like keeping the BOB on your back instead of on someone else's. Also, once those sprays have been discharged I find they are great for spicing up food (may not be healthy but spice-tastic).

All in all that is a great looking pack and it is obvious you've put some thought into it.
