Montbell Trail Lumbar Pack 7 - ThymeMontbell's Trail Lumbar Pack is a hard wearing lumbar pack built for hiking. Designed for comfort and function out on the trail, those adjustable compression straps keep it close to your body so it's not bobbing about as you wander over rocks and roots. With 7 litres of storage, it's big enough for your snacks and supplies, and those external storage straps are the ideal place to carry an extra layer for when you get out onto the hilltops.
