These are the perfect sizes for most situations, with the rigid aluminum mesh promoting airflow to keep your bait cool in hot conditions, while also reducing weight.
The Large model (bottom right of main image) is twin knuckled with the capacity to hold 6 3-pint bait boxes with further space for other items.
The XL model (top left of main image) is constructed in 2 sections which simply slot together. It's recommended that support legs and arms are used due to the larger size, and because of this – two 36mm legs are supplied. You can also use this as a single piece with one support leg if required.
