The GENERATION 2.0 WODGrips - 100% Hand Made -Hand Protection Grips - Tear Up WODs, Not Your Hands Our Generation 2 WODGrips consist of a composite of materials to provide flexion for handstands and burpees, and toughness where you make contact with the rig and barbell so you can keep hitting muscle ups and cleans. Gen 2 features military grade 1000 denier ballistic nylon. This is the same ballistic nylon found in military packs, load bearing vests, and flak jackets. The material is thin, rot resistant, tear resistant, and extremely abrasion resistant. You wont have to remove them when transitioning from closed grip to open palm exercises so you can wear them through your entire WOD. Wide wrist straps allow you to use WODGrips with your favorite wrist wraps. WODGrips work even when soaked with sweat -- and they work even better chalked up. Easy to maintain, just wash in warm water and tumble dry. The colors wont bleed and the material wont shrink. SIZING: Measure from your wrist to the base of your middle finger. If you are between sizes, go with the smaller size, as the fabric will stretch to adapt to your hand. YOUTH/XS = up to 3.5" SMALL = 3.5" to 4" MEDIUM = 4"to 4.5" LARGE = 4.5" and up
