The newest Trek & Train model has been updated to include a magnetic closure and is made with 600D ("backpack") fabric. Superior quality and design makes this a bait bag that will last through who knows how many dogs! Magnetic closure lets you open and close with one hand with ease. Zipper down one side creates a roomy compartment out of the entire back panel (great for an outing when you need to bring money, credit cards, keys, or pickup bags) Grey inside lining allows better visibility D-ring on side for attaching leads or training items. Attaches with a clip, includes loops if you prefer to thread a belt through (OPTIONAL ADD ON) Features include: Magnetic closure with pull tab for easy open/close Front pocket 4" W x 3" H with a velcro closure. Roomy enough to hold various types of clickers, pickup bags or special bait, it keeps its shape and looks attractive if left empty.
