Yoga exercise carpets are usually thin and to some extent cheap in nature, and I don't mean the type of cheap which would make you shy at the thought of going out in society with it either. No, yoga exercise mats are styled with the express purpose of providing a non-slip surface for which to practice your yoga poses on, however definitely the other connotation of tacky can pertain to some of the patterns that can be seen hauling into several yoga class.
Being a quiet saving-minded person myself, I like the notion of my yoga exercise mat being crafted of a renewable source which is biodegradable should it ever come time to change the mat. A best option to that conclusion is a yoga exercise mat crafted of natural rubber. It provides excellent traction even when damp. This makes it a great mat to exercise with at the beach, particularly if your exercise lasts a bit more time than estimated and the waves seize the corners of your mat when waves is coming in. You can just pick your mat up, change place and not have to worry so much about drying it off. A rubber mat is even notorious for being very dense, hard and durable, meaning it will last and might be put during a bit of penalty before it comes time to replace it.
If you don't think of wandering so much for your daily routine and prefer a more padded and comfortable yoga workout mat, then you might look into a mat make up of cotton. Many cotton yoga exercise mats are conveniently rolled up and stored away, entirely with some ties affix to them to keep them rolled up when not in use. With a small layer of cotton batting padding the yoga exercise mat it can aid give additional hold while doing many upturned postures that could give a bit of painful stress on the neck.
