All Wenaha Dog Packs are made from high quality 500 denier Cordura nylon. The inside is double-stitched for extra strength. A solid yoke across the back of the pack allows for better weight distribution. Weight is carried low on the sides and maintains a proper balance for the dog's comfort. Wenaha Dog Packs are perfect all-purpose packs, light enough for short walks yet strong enough for mountain travel. A padded under saddle attaches to the pack with a heavy-duty hook-and-loop strip. You can remove the pack quickly and easily without unharnessing the dog. It works well for lunch stops or when you need to remove the pack to cross a stream. Brush guards, made from nylon ballistic, are a basic feature on the Wenaha Dog Packs. This durable outer fabric helps protect packs from undue damage from brush and rocks. A layer of foam is sandwiched between the outer Cordura layer and the under layer of canvas. The canvas absorbs moisture and keeps the pack from slipping. The buckles and straps are stitched to the pack. All buckles are the quick release type and are padded underneath for added comfort. Wenaha Dog Packs come with a 10-12' strap (depending on the size) for use during mountain travel. Training tips and instructions are included.
