The Redwood is a heavy duty oversized rectangle bag. The Redwood series use Techloft Insulation. Techloft Insulation consists of multi-hole staple-length micro-denier fibers that have a siliconized finish for maximum insulation, loft, and compactness. The TechLoft insulation will keep you warm and toasty on those colder nights when you'd prefer to have more wiggle room than you get with your mummy bag. It uses 2-layer offset construction to eliminate cold spots. For transporting, the bag includes 3 webbing straps with quick release buckles that keep your "rolled-up bag" secure.
Have not used it outside but I’ve used it in the house and it’s perfect. Quality is top notch, heavy material was used on this bag. I’m going to order another one more so whoever goes camping with me can feel the comfort I’m sleeping in.
Sleeping bag is very heavy and warm. Outside is Carhartt like (very durable)! Took it camping in tent trailer cold night used bag as blanket and was very warm. If you want a warm bag this it is it. Not for hiking . Very heavy and bulky
If you don’t care about weight or size, because it is big and heavy compared to modern backpacking bags, then this is the bag for you. I’m 6’2, 190 and I have plenty of room in this bag, with plenty of extra room for my day time clothes in the bag with me. This bag is warm, I’ve used it in a three season tent in weather down in the teens, as well as in the back of my car. Excellent, excellent value for the money.
