GFB Whistling Trumpet (suits all valves)The 5702 can be used in place of the standard trumpet on all GFB valves, and will make the whistling sound more readily than the 5701 (high boost and RPM is required to get the whistle from a 5701), and at a slightly higher pitch.? Like the 5701 however, it is necessary to run the valve so that all (or most) of the air vents through the trumpet ? Respons valves will typically not generate the velocity required to whistle when set to 50 50 venting.

Super big
Color: Light Grey, Size: 36
Bought 4 pairs of these shorts and had to send all four pairs back. They run very big, in the waist and overall. They are super long. My son is 5'10" and he said they were way longer than he wanted them. They appear to be good quality, heavy material jean shorts. I would recommend sizing down if this is the look you're going for. And they're a little pricey.

Shorts
Color: Green, Size: 40
With exception of the seeming low quality zippers and fasteners, the shorts are nice in fit and style.

Pretty good overall just a little long

Nice material and nice baggy fit just a little too long it’s almost at my ankles so I got them cut down.
