BAM Hoodies - for Violin - fits Hightech Contoured Case

love my BAM but have cold winters to deal with during concert seasons. these hoodies protect and brighten the day. have two for my two instruments cases - violet and grey. both are great.

When I first bought my Bam contoured case, I noticed that it really protected my violin (compared to the bobelock case I had prior that chipped the corners of my instrument.) However, I noticed that in winter (or extreme a/c which way too many buildings
in the US have), my violin would be cold, even with a half wool mini blanket I made for it, covered in a silk violin bag, and a thick velvet/ silk violin blanket. Also, in summer, it'd be pretty warm. After buying the hoodie, many of these troubles have disappeared!
In winter, my violin isn't cold and this past summer, I was in south east Europe where it was 90-95 degrees Fahrenheit daily with barely any air conditioning, and the violin was still okay with the hoodie!! I've also noticed that it's pretty water resistant.
I'm not sure about totally water proof, but without it, I think water can seem into the case. With it, the case is pretty dry. Yes, you are able to still uses backpack straps with it. Seriously, if you own the Bam contoured case, I HIGHLY advise this item!!
