When the weather turns crisp, that's when I want to be outside as much as possible. Fall is great for outdoor activities, whether you're into walks around the block, hiking a trail or biking through valleys full of multi-colored leaves.

With all the confusion (and anger) out there about aluminum bottles with liners and whether those liners are BPA-free or not, why even risk it? Stainless steel bottles do not need to be lined. There are so many stainless steel options out there that there's really no reason to bother with the aluminum.

Since I always carry a water bottle on my outings, I've compiled a list of great ones that are especially activity friendly.

Klean Kanteen 27oz. Classic image

Klean Kanteen Stainless Steel bottles (prices start at $14.95)

Perhaps the most well-known stainless steel bottle is the Klean Kanteen. The bottle is available in four sizes (12 oz., 18 oz., 27 oz. and 40 oz.) with seven colors and two cap styles. The customization options with this bottle are one of the best things about it.

If you plan on biking with your bottle, their website also sells bike cages that fit their 27 oz. Kanteens.

Also, during the month of October, $4 will be donated for every pink bottle sold.

CamelBak 16oz. insulated stainless steel bottle

CamelBak 16 oz. Insulated Stainless Steel bottle ($30)

I love hiking with my CamelBak backpack, so I was excited to learn the company also offers stainless steel bottles featuring their signature straw. (To make the liquid come out, you lightly bite on the straw and sip the water.)

If you're interested in this bottle, keep in mind you shouldn't use the straw if you have filled the bottle with hot water. For this reason, the straw is removable and you can just drink from the lip of the container.

Safe Sporter 16oz. stainless steel bottle

Safe Sporter 16 oz. Stainless Steel bottle ($16)

I like this bottle for its hourglass shape and insulated hand grip. It also has a cap to protect the water spout. If you're hiking in a dusty area (or biking with a bottle in a cage on your bike), this bottle would be a good choice to keep out the grit and grime from the road. No one wants to drink water that tastes like gravel.

Thermos 26oz. stainless steel bottle

Thermos 26 oz. Stainless Steel Intak Hydration bottle ($22.99)

In true Thermos fashion, this bottle keeps contents cold for 18 hours. If your plans involve going somewhere with few opportunities to refill your bottle with cold water, this would be a good choice.

Though it has a top to protect the lip area from dirt, it twists off. Keep in mind that this may require more effort and focus than a protective top that just snaps.

Green Bottle 20oz. stainless steel

Green Bottle 20 oz. Stainless Steel bottle ($16.99)

This bottle comes with two interchangeable tops: a sports top (with a protective cap to keep out the dirt) and a loop top (with a carabiner to clip onto your backpack or belt).

The bottle itself weighs in at 4.6 ounces, which is nice if you plan on carrying the bottle around with you all day.

Another great thing about this bottle is the pattern choices. It is available with the two tops in 22 different colors and prints.

Happy trails and happy hydrating!
