    Great golf shirt!
    Size: Small, Color: White/Light Blue Stripe
    My son loves this shirt! It has silky smooth wrinkle-fabric and is nice and cool on the golf course. It is true to size, hangs well (no clinging) and allows full range of movement. It washes great! I wash and dry in the machine and stains come right out.

    Beautiful colors, nice golf shirt
    Size: XX-Large, Color: Aqua Blue Stripe
    I always read reviews before I purchase and this golf shirt had positive ones. I ordered one so I could see the fit (true to size), and see how it laundered. Both are a thumbs up from me. Beautiful vibrant color, at a price comparable or less than what you might find in store. The SPF protection is a plus. I will be ordering more.

    Golf shirt
    Size: Large, Color: Aqua Blue Stripe
    I like the shirt is comfortable, but I thought the ad said three of them and Allie got one. Haven’t looked to see how much I paid for it.

    I like these fleece-lined pants
    Color: Black, Size: 32W x 32L
    For these specific pants, the 32" inseam is accurate and fits as expected. The fleece lining was great in high 40's and did not feel too warm when the temp climbed into the 60's. I was impressed enough to buy a second pair. They appear to be well made and look great.

    Perfect. Warmth without bulk
    Color: Grey, Size: 34W x 30L
    Perfect thickness and insulation level. Warmth without bulk. Stylish and do a good job disguising what they are. Cut is similar to "regular" or "straight" cut jeans. Will be ordering other colors...
