Note from Lone Star Knife & Supply: The black aluminum Amphibian Mini in Apocalyptic is the understated version of the platform. The Apocalyptic finish adds depth to the blade without going loud. 3.25" M390MK, RAM-LOK, North Carolina made.

Great sleeping bag
Color: Ocean Blue, Style: Everyday 3 Season 50-80° F
Great size for my 10 year old son. Nice and long. The material is soft and warm. The zipper zips fast. There is like a hoodie on the top to go over your head to keep you warm.

Great for school trips and camping
Color: Sunburst Orange, Style: Everyday 3 Season 50-80° F, Color: Sunburst Orange, Style: Everyday 3 Season 50-80° F
My daughter went on a school camp trip and needed a sleeping bag, so I decided to get this one. I chose the adult size instead of the kids’ version so we can use it in the future too. It turned out to be a great choice — it’s roomy and comfortable, and even I fit inside easily. The material feels soft and pleasant to the touch, and the zipper works smoothly without getting stuck. It keeps you warm at night but doesn’t feel too hot, which is perfect for cool-weather camping. I did notice that along the edges there’s a section without insulation for quite a bit of distance — not a big issue, but something to be aware of. I tried to show this part in my video. The color is bright and cheerful, exactly as shown in the pictures. Overall, I’m very happy with this purchase — it’s lightweight, cozy, and easy to use. The only challenge is rolling it up and fitting it back into the carrying bag. Even for me, it took some effort since the sleeping bag is quite bulky. The material seems sturdy and well-made, but we’ve only used it once, so time will tell about its durability. Maybe the manufacturer could improve that part in the future. Still, it’s a great option for school trips, camping, and sleepovers.

Warm, comfortable, and great value for the price
Color: Ocean Blue, Style: Everyday 3 Season 50-80° F
I bought this sleeping bag for my son on a recent camping trip, and it performed surprisingly well. It warms up quickly once you’re inside, and the material feels soft and comfortable against the skin. The zipper runs smoothly and doesn’t get stuck easily, which is a big plus. It’s lightweight and packs down small, so it’s easy to carry and doesn’t take much space in his backpack. However, It’s not warm enough for very cold nights below the temperature rating, so if you’re camping in winter, you may need an extra blanket or liner. Overall, for the price, this sleeping bag is an excellent buy—comfortable, warm, and very practical. I would like to give five stars.

I’m very impressed with this sleeping bag! It’s incredibly comfortable, warm, and lightweight, making it perfect for camping trips and sleepovers. The material feels soft on the inside but durable on the outside, and the zipper works smoothly without snagging. It kept me warm throughout the night without feeling too heavy, and it rolls up easily for storage and travel. Overall, it’s great quality for the price, and I would definitely recommend it to anyone looking for a reliable and cozy sleeping bag.
