Lucky Bums Sizing Chart
Backpack Sizing & Load:
Our packs are engineered for kids and therefore sized based on torso length. Fit is the key to pack performance so take the time to get it right. To find torso length, measure the back along the spine from the level of the iliac crest (the top of the hipbones) to the C7 (the knobby bone at the base of the neck). Our adjustable shoulder and hip belt straps will enable the necessary fit after selecting the suitable pack. A properly fitted hip belt rides centered over the hipbones and needs to be snug for maximum carrying efficiency.
When is comes to the backpack load, we recommend less than 1/4 or 25% of the child's own body weight in total backpack weight. That's why we engineer our packs carrying capacity in conjunction with size/torso measurements. We cringe when we see kids with adult sized packs strapped on practically falling backwards under the weight of the load - most noticeable during the school year. We're working on this problem so stay tuned.close

Definitely a winner

I bought these speakers for the Boston Avon walk (39.3 miles to raise money and awareness for breast cancer). They do not allow ear buds/head phones but I wanted music to keep our spirits up. I attached these babies to my fanny pack (yes, fanny pack) and we rocked out for miles of smiles! Only had to change the batteries once which is amazing. AND they were loud enough for my group to hear and then some. I am thrilled with this purchase thus far. I can't wait to take them out kayaking next.Pros: Great design, Build quality, Performance, Ease of use, Great value, good volume for the size, no distortion at max volume
