I didn’t buy this camelbak from Amazon. I just wanted to leave a review because I like it and I trust it. It’s called thermobak for a reason as it does a decent job of insulating. I use this for hunting. I use its straps to secure to my pack frame. When it’s cold out just put a hand warmer against the water bladder and it’ll keep your water from freezing for about 8hrs. Results may vary based on temps. I impregnated the fabric with silicone waterproofing and it didn’t affect the performance at all. I’ve used it on its own for mountain biking and hiking. Keeps cold water cold too.
