T-Shirt Sizing Charts
All measurements are approximations. Length and width vary slightly from manufacturer to manufacturer.

Shirt Sizing Chart
Taking your measurements is easy with a measuring tape and good posture. Make sure that the tape lays flat, and that the area you're measuring is in natural position.

• Chest: With your arms relaxed at your sides, measure around the fullest part of your chest, keeping the measuring tape level and parallel to the floor around both the chest and ribcage.
• Neck: Measure a shirt collar that fits you well. Button the collar and place the tape's starting point behind the button. Wrap the tape all the way around the inside of the collar until it meets its starting point.
• Sleeve Length: With your arms relaxed at your side and slightly bent, measure from the center back of your neck, over the point of your shoulder, and down the outside of your arm to your wrist.

Determining Your Hat Size
Choosing the right size fitted hat is an important yet simple process.

• Fitted hats require that you know your head size. You do not have to measure you head if you are buying an adjustable (One-size-fits-all) hat.
• To figure out your hat size, measure your head with a tape measure about a half-inch above your eyebrows where your hat will rest. If you don't have a tape measure, use a string and measure it against a ruler.
• If you are unsure or between sizes, buy the larger size
• Use the chart below to determine your hat size

BDU Size Chart

Taking your measurements is easy with a measuring tape and good posture. Make sure that the tape lays flat, and that the area you're measuring is in natural position.

• Waist: Measure over shirt at your natural waist.
• Inseam: Use a pair of similar pants that fit you well. Lay them flat on the ground with the side seam facing up. Use your hands to smooth and straighten front and back creases. Then measure the length of the inside seam from the crotch to the bottom of the hem.
• Chest: Place the tape line well up under the arms, straight across the back, over the blades, and over the chest in the front.

Fin Fit Tips

Overall, you should wear your fins with a snug, stable fit, but not so tight that they pinch your foot anywhere. If you have room to move your toes and the fins stay on when you try kicking them out of the water, you've achieved a good fit.

Open-heel fins should be worn with a neoprene boot for protection. If you plan to wear a boot underneath your fins, add 1 size to your fin size to leave room.

When getting into adjustable fins, move the strap to the loosest position and insert your entire foot in the foot-pocket. Then make adjustments to the strap according to fit.

For full ankle support, make sure that the fin's foot-pocket nearly covers edge of your heel without engulfing it, and that its upper lip meets your instep.

*Please note: These fin sizes are based on bare feet.  If wearing dive booties, such as the Echo Zip Bootie, we recommend the size XXL fins.  If you wear a size 12 or larger, we do not recommend wearing booties.  We do not recommend molded sole boots such as the Manta Boot for these fins.

OTB Sizing Guide

OTB Footwear fits on the “fuller” side, similar to, but not quite a wide, however we include a spacer or “filler” in each box.

For those of you who are a ½ size, below is an example to help you select the proper size.EXAMPLE:
If you are on the smaller side of a 9 ½ (you sometimes buy a 9 or 9 ½) we recommend you purchase a size 9.
If you are on the larger side of a 9 ½ (you sometimes buy a 9 ½ or a 10) we recommend you purchase a size 10.

We put a spacer in each box to take up the room inside of the boot if the fit is too large. The flat perforated spacer should be placed below the footbed. This will take up space and help you get the correct fit.

Wearing a 3mm neoprene sock or a sock footed dry suit??
One point to note, if you are wearing a pair of 3mm neoprene socks, or a sock footed dry suit, we recommend you purchase the next size up.
