We have only the Compact size in stock: 4.6.26 only one left.

The MB5 is a lightweight fiberglass case made for screw bell French horns by Marcus Bonna in Brazil.  The fiberglass shell is surrounded by a nylon cover that is easily removed if repair or replacement is ever necessary.  The MB5 case includes backpack straps, a shoulder strap, several movable foam pads, storage pouch, a double mouthpiece pouch and ID tag. 

The case weighs 7.0 lbs and the dimensions are 23x14x8.5".

Two small interior spaces will hold your small accessories.  The lid includes storage room for two mutes.  The exterior has a small accessory pocket at the top of the lid and a sheet music pocket on the back near the strap mounting rings.

This case protects your horn with a plush interior and a snug fit for the horn body.  The body straps down to the floor of the case to prevent movement.  The bell flare slides into a padded sleeve that rests on top of the body and is pinched slightly when the case is closed.  Truly, we have feared damage from having the bell flare located there, but it never happens.  Never have we heard of such a bell injury to a horn traveling in an MB5 or similar case.  The caveat is that these cases are designed for use as hand luggage, and are not to be trusted to checked baggage or airport baggage handlers. 

This case actually comes in 3 sizes:

  • Standard:  fits nearly all double horns of normal size, Conn, Yamaha, Hoyer, Holton.  Now fits the Alexander 103, though the case is larger than it needs to be
  • Compact: This case is about 2" shorter and has a bit less storage inside.  Fits many Kruspe and Alexander style horns, maybe others.  For Alexander, see the MB5 Baby model.
  • XL: The shell is the same as the standard model, but the interior accessory compartment is smaller and the brace near the bottom to support the horn body is moved outward for larger horns.  Note:  New models a movable interior brace so you should be able to fit a variety of horns into the standard case.  Large wrap Geyer style horns like a Hoyer G10, Duerke LDx5, and Atkinson may be better in the XL

Instruments shown in the photos are a Paxman Series 4 and an Alexander 103.

As with all Bonna cases, many colors are available.  Given a bit of waiting, we're glad to offer this case in any single or two-tone color scheme that you'd like.  We receive shipments four times a year, so 30-90 days is a common wait time.

We try to stock several color combinations:

  • black nylon
  • black & blue nylon
  • black & green nylon
  • black & burgundy nylon
  • black & turquoise nylon

Other colors available include red, yellow, orange, light blue, light green, dark green, purple, grey and pink.

A leather outer cover is also available by special order.  See the drop down menu for pricing.  The leather adds less than a pound of weight.  The leather is stylish and may wear a bit longer than nylon, but you will get many years of use out of either.  The full spectrum of colors is available for leather cases.  Carbon shell is available, which saves less than a pound, but significant weight.

Compared to the MB7 case, this MB5 may be slightly more comfortable to carry as a back for some players, especially those of the petite size, due to its symmetry.  The MB7 may be more comfortable carried as a single shoulder strap case.

Weight: 7 lbs, 12 oz

Dimensions: 8x15x24"

Great fit, simple style, and comfortable for all-day wear
Style: 7" Swim Trunk, Color: Aqua Blue, Size: Small
These swim trunks are a solid find—comfortable, well-made, and true to size. The 7-inch length is just right: not too long, not too short. They dry fairly quickly and have a mesh lining that’s supportive without being annoying. The style is simple and classic, and they’ve held up well through swimming, beach trips, and even some light hiking. Great value for the price.

Not quite as good as top name brands but pretty decent so far for the money
Style: 7" Swim Trunk, Color: Black, Size: Large
I compare these to the Columbia version with similar design. I ordered the large, which is my Columbia size. I note that the Amazon version was slightly tighter in the waist and the lining was significantly tighter in the legs. The elastic bands are both well structured and not flimsy. I live in Florida and I wear these swim trunks as my everyday outdoor shorts, whether working in the yard, biking, walking, or whatever. I note that when I tried to wear these in my exercise classes, the legs tend to stick and not slide up the legs when I squat, which is not a problem with the Columbia shorts. Lest you think it unfair to compare these two brands, Columbia puts their shorts on sale a couple of times a year for about the same price. Of course, you have to pay attention regularly to their website and it doesn't help if you need shorts now. I will continue to use these shorts for outdoor work and activities and they seem to be holding up fine for now. Next time I will probably get the XL for comfort if Columbia doesn't have a big sale (unless I can manage to lose a little visceral fat I have collected the last few years!). One other positive and one negative. I like that the black shorts have a black tie string, but the blue pants have a white string which shows dirt and looks a bit cheaper than if the string was blue. White is fine for swim trunks, but when they are used as all purpose volley shorts it doesn't show well with white string. I saw some complaints in the comments saying these shorts were not quick drying. I note they are every bit as fast drying as my Columbia and Nike shorts which are advertised as quick drying. As you might imagine a few hours working in the Florida sun I can sweat a ton so I can certainly judge drying speed.
