Thinsulate brand insulation can be installed in the case to mitigate the effects of extreme temperature conditions. Thinsulate is installed in the case under the foam and fabric, so you won’t see it. But you’ll know it’s there when you open the case and pick up your instrument on a blistering or freezing day. Thinsulate is made in the USA by the 3M company. Price $120 ($80 for mandolin)
Insulated professional-grade cloth covers are available to protect the case from surface wear, and supply an added layer of temperature control. Colorado Case Co. makes our premium covers in the USA to exactly fit Hoffee Cases. Price $220 ($200 for mandolin)
Comfortable, high-quality padded carrying straps in shoulder (single strap) and backpack (double strap) configurations. Straps clip on and off D-rings securely mounted to the case, and are made for us right here in the USA by Neotech. Price $30 for shoulder strap, $50 for backpack straps.
Twist latches for those who prefer an alternative to locking draw latches. A padlock hasp at the center position allows the user to install a lock of your choice, including a TSA lock. Price $25
