Don’t hold up/good Customer Service.
Size: 10.5, Color: Army Green
Please read full review. Where to begin. The boots are comfortable, decent waterproofing, they feel/look well constructed. Unfortunately they did not hold up well, I hikes less than 10 times. My left foot began to hurt on top near bottom of the lace, I tried every lacing method and it still hurt, leading to potential blisters. It was not a break in issue the boots were initially comfortable to wear then around hike 6 they hurt. Reached out to the company they were partially helpful offering a coupon on their website. Their shoes are significantly higher in price on their website. It could have been a lemon pair of boots. Buy with caution. Updated: 4/9/26-CS reached out to me and offered full refund or new pair of boots. I do hike often so I went with the new pair of boots. I will create a new review in the future /update this review. A+ for their CS. Initial review was 2 stars I increased to 3 stars if these boots hold up the score will go higher.

Nice Grill Cover
Size: 55 Inch, Color: black
I bought this as a replacement cover. It's durably made. It's not too thick or heavy. It fits nicely over my grill. The handles make it easy to put on and take off.

Durable, Long-Lasting, Doesn’t Fade in the Sun!!!
Size: 50 Inch, Color: black, Size: 50 Inch, Color: black
I’ve had this grill cover for almost a year now. But it last summer and it has been on my grill that is on open porch (no roof/overhang/cover protect protecting it from the elements). This particular area of the porch gets a ton of direct sunlight all day long as well. Needless to say, I am incredibly impressed by the material of this cover. It looks almost brand new even after a year of use and exposure to the elements. The fact that it didn’t even get faded in the sun a little bit blows my mind. Great product and excellent value! Highly recommend.
