Photo of Padding OptionsWe use a polyester fiber fill which is quilted to soft yet tough black nylon lining (guaranteed not to bleed color). We have not seen any deterioration in our padding since we started making covers in 1992, unlike foam padding which can disintegrate in time. The photo shows the difference between single and double. The single is approximately 3/8″ thick (a little less than a centimeter) and the double padding is approximately 5/8″ (about 1 1/2 centimeters). Our padding feels more like a glorified moving blanket and folds up easily to store away.

Handle Openings

All openings are reinforced, so they will not fray or come apart like common bound openings. Additional openings for jacks, etc., cost $10 each.

Duffel/Briefcase Style Wrap-Around Handles (for Clamshell Gig Bag)

Photo of Duffel Bags Webbing strapping wraps all the way around the bag to keep the weight off of the zipper. Two handles come together at the top with a Velcro grip (like a duffel bag). Can handle heavy weights up to 75# (34 kg). Let us know if your gear weighs more than 75# and we can discuss ways to possibly accommodate. (Formally known as the Briefcase Gig Bag)

Standard Handle Grip or Cushioned Handle Grip for Duffel / Briefcase style Clamshell Gig Bag

Molded Plastic Handle

As a primary handle (on top when you’re carrying your gig bag), the molded plastic handle is great if your gear is 20# (9 kg) or less. For more weight than that, there’s concern that the weight will put stress on the zipper and it’s recommended that you use the Duffel / Briefcase Style Wrap-Around handles instead.

Sometimes it’s nice to have an extra handle or two on your Gig Bag. They can handle weights up to 75# (35 kg) but do let us know if your gear is over 60# (27 kg) so we are sure to add reinforcement.

Handle Flaps to cover opening with Velcro

Not listed as an option in the cart, but available for $10 each. You can add them to the cart as Custom Work Discussed with Studio Slips and just be sure to put a note on the order that you want them.


For additional storage space, we can add an external zippered pocket. Pockets can be padded or non-padded.

Bottom Closing Strap for Cover

We can add a webbed strap which is sewn to the bottom back of your cover and secures with Velcro to the front to keep it snugly in place.

Leather Strips on the bottom of Clamshell Gig Bag

For extra protection, we can reinforce the bottom of your bag with heavy duty leather. The strips are 1/8″ thick, 5″ wide, and run from front to back on both sides of the bottom of the bag.

Shoulder Pad with Shoulder Strap for Clamshell Gig Bag

Can be added to Clamshell Gig Bags

Caster Openings on Clamshell Gig Bag

Reinforced caster openings are available for $35. Please email to request a template to measure your casters or wheels.

What People Are Saying
I received my clamshell for my Carr Viceroy and just wanted to say thank you so much! It fits like a glove and instantly took my worry out of accidentally bumping my $2,800 amp up against something.

Susan, I wanted to let you know that I received the Studio Slips "Padded Slip Cover" for my Ultrasound Pro250 today. I believe that you indicated that this was the first time that you made a cover for an Ultrasound Pro250. You would never know it. It fits absolutely perfectly. I am impressed. I almost went with a Tuki Cover. I'm so glad that I chose Studio Slips. From the detailed measurements that you require through your well organized website and from our communications before you began the manufacturing process, I had an instinct that you would do quality work and I was correct. It is clearly evident that both the materials and workmanship are absolutely first rate in every respect. I wanted let you know how pleased I am with my Studio Slips cover and I want to thank you very much. It's really nice when everything goes right. Thanks again!
