What Makes a Defense Head Different
Defense Head Characteristics
Defense heads are wider than attack heads — the wider face helps you scoop ground balls and gives a bigger catching window when tracking a 90 mph clear. Defense shafts are also longer (60″ vs 42″ for attack), which is why d-poles are a separate purchase from the head. Any defense head will work with a standard d-shaft.
Key qualities to look for: stiffness (so the pocket doesn’t warp when you check), width (for ground balls and catches), and durability (defenders beat their equipment). Weight is less critical — you’re not shooting from 15 yards, so a slightly heavier head is a fair trade for extra strength.
StringKing Mark 2D — Best Overall Defense Head
Price: ~$70–90 | Best For: D-poles and LSMs at any competitive level
The Mark 2D is what you see on sidelines at high school and college D1 programs. StringKing’s Type 2 plastic is legitimately stiffer and more warp-resistant than most competitors — important because defense heads get beaten up constantly. The wide face gives you a big catching window and the offset design makes ground balls easier to scoop cleanly.
StringKing also makes their own mesh (Type 4 and Type 5) which pairs perfectly with the Mark 2D if you want a complete pocket setup from one brand.
Pros
- Industry-leading stiffness from StringKing Type 2 plastic
- Warp-resistant under constant checking pressure
- Used at every level from high school to D1 college
- Pairs well with StringKing mesh for a complete setup
Cons
- Premium price ($70+)
- Wide face isn’t ideal for faceoff-specialist midfielders
Bottom line: The best defensive lacrosse head. Used at every level from high school to D1 college.
STX Hammer 900 — Best for Physical Defenders
Price: ~$65–85 | Best For: Aggressive, physical defenders who go through gear fast
The Hammer 900 is built like its name suggests — one of the most durable defense heads available. The sidewalls are reinforced to handle the kind of abuse that comes from checking attackmen 50+ times per game. The wide scoop is excellent for ground balls. If you play physical defense and go through heads quickly, the Hammer 900’s durability often makes it cheaper long-term than replacing budget heads every season.
Pros
- Reinforced sidewalls handle aggressive checking far longer than budget options
- Wide scoop for ground ball dominance
- Proven durability — a frequent choice for physical D-poles
Cons
- Heavier than the Mark 2D
- Fewer color options available
Bottom line: Most durable defense head. Built for physical, aggressive defenders.
Defense Head vs. Midfield Head for D-Poles
Which head goes on your d-pole?
Use a defensive head if: You’re a traditional lockdown defender, you play heavy contact, or your game relies on ground ball dominance. The wider face and stiffer sidewalls are built for what you do.
Consider a midfield head if: Your coach emphasizes transition and outlet passing, or you play a technique-based defensive style rather than brute force. A midfield head like the StringKing Mark 2M on your d-pole improves accuracy on outlet clears without giving up too much width.
FAQ: Defense Lacrosse Heads
What makes a lacrosse head designed for defense?
Defense heads are wider, stiffer, and more durable than attack or mid heads. The extra width gives defensemen a larger catching surface and more leverage on ground balls. Stiffness matters because defensive heads take constant stick-checking impacts that would warp a softer head.
Can a defensive head be used by a short-stick midfielder?
Yes, and some short-stick middies prefer them for the ground ball advantage. The trade-off is reduced passing and shooting finesse due to the extra width and stiffness. Offensive middies should stick with attack or mid heads. Defensive or two-way middies can do well with a defensive or stiff mid head.
What shaft should I pair with a defensive head?
Defense poles are typically 60 inches and work with any defensive head — all use standard shaft diameters. Alloy shafts are heavier and great for physical play. Carbon or titanium composite shafts are lighter if you want more speed while keeping your reach advantage.
Do defensive heads come strung?
Some do, most don’t. Defensive heads are often sold unstrung because pocket preferences vary — some defenders prefer a channel pocket for quick passes, others prefer a flat pocket that’s harder to dislodge. Have a shop string it or learn yourself. A proper defensive pocket makes a real difference in ground ball battles.
How do I know when to replace my defensive head?
Replace when the plastic shows cracks (especially around the throat and sidewalls), when the head visibly warps during play, or when checks consistently knock your stick out of position in ways they didn’t before. Quality defensive heads like the Mark 2D and STX Hammer 900 typically last 1–2 full seasons of hard defensive play.
Key Takeaways
📋 Key Takeaways
- The StringKing Mark 2D is the best defense head, full stop. Type 2 plastic is genuinely stiffer and more warp-resistant than the competition. The premium price is worth it for any serious d-pole.
- Physical defenders who go through gear: look at the STX Hammer 900. The reinforced sidewalls outlast most options under heavy checking loads — often cheaper long-term than replacing budget heads each season.
- Stiffness is the most important spec for defense heads. A warped pocket is a pocket that holds balls inconsistently. Choose stiff plastic over weight savings every time on defense.
- Consider a mid head on your d-pole if you’re a transition-first defender. The StringKing Mark 2M or similar gives you better outlet passing accuracy without completely giving up the width advantage.
- Don’t skip stringing quality. A wide, stiff head with a bad pocket is still a bad stick. Have your defensive head strung to match your style — channel pocket for quick clears, flat pocket for ground ball battles.
