Dark glasses (see also Snow blindness, p. 141.— Glasses should provide side protection against glare and driving snow. They must be adequately ventilated to reduce fogging. Color should be quite dark, preferably in nonbreakable glass. Plastic lenses may not be optically correct, and may scratch easily. They weigh little, however, and do not break readily. Polaroid removes only a small portion of snow glare. Miscellaneous.—Pocket knife should be of good steel with screwdriver and leather punch for repair and adjustment of skis. Matches should be carried in the various pockets and parts of the pack where they are most likely to remain dry. Reserve matches should always be carried in a waterproof case in the emergency kit. Matches may be waterproofed by covering them with nitrocellulose lacquer. |
