Mask "Krot" with neck.
Made from a helmet-mask from a GP-5 gas mask, gray or black.
Breathing through a glued tube, no exhalation valve.
To ensure that the mask fits comfortably, it is important to determine the correct size.
To do this you need to measure the circumference of your head as shown in the picture:
Then determine your size using the table:
| Measurement result in cm | Helmet mask size |
| up to 61 | 0 |
| 61-63 | 1 |
| 63.5-65.5 | 2 |
| 66-68 | 3 |
| 68.5-71 and more | 4 |
The main photo shows a mask in black.
A silver neck is glued to a gray mask (as the most suitable color), and a black neck is glued to a black mask. If you have any ideas about the color of the neck, describe them in the comments when placing your order.
To make it easier to put on a gas mask, you can glue a zipper or make lacing on the back, but keep in mind that the gas mask will most likely lose its tightness.
The "Hangman's Collar" neck is only possible without zipper or lacing.
