KOLDWR Pro (KoldWear) vs IcedBallz: Which Sauna Cooling Underwear Should You Buy?
KoldWear rebranded as KOLDWR Pro — now taking pre-orders at $59 with 8–10 week shipping from Dubai. IcedBallz ships now at $69 with 45–60 min cooling. Here's the honest breakdown.
⚡ Quick Verdict
KOLDWR Pro is the closest direct competitor to IcedBallz — same concept of cotton underwear with gel pack cooling pockets. At $59 pre-order, it's $10 cheaper. But there are real tradeoffs: 8–10 week shipping, only 30+ min cooling (vs IcedBallz's 45–60 min), flat gel packs (vs anatomically shaped), and Dubai-based shipping with $15 flat shipping for single units. IcedBallz costs $10 more but ships now and delivers significantly longer cooling.
What Happened to KoldWear?
KoldWear — the cooling underwear brand that sold out with 847+ on the waitlist — has rebranded as KOLDWR Pro (koldwr.com). The new version launched as a pre-order, based in Dubai, with Bryan Johnson-inspired marketing focused on male fertility protection during sauna sessions.
The core product is similar: 100% cotton boxer briefs with integrated pockets for BPA-free gel packs. You freeze the gel packs for 2+ hours, insert them before your sauna session, and get active cooling for 30+ minutes. The kit includes 1 pair of underwear + 2 gel packs.

Where IcedBallz Wins
- Ships now — not in 8–10 weeks. KOLDWR Pro is still a pre-order. You're paying today for something that may not arrive until July 2026. IcedBallz ships immediately.
- 45–60 min cooling vs 30+ min. IcedBallz delivers 50–100% more cooling time per session. That's the difference between one full sauna round and needing to re-freeze mid-session.
- Anatomically shaped ice pack. KOLDWR uses flat gel packs. IcedBallz uses a crotch-shaped ice pack designed for proper anatomical fit — better contact, better cooling, more comfort.
- Lower shipping cost for single units. At $6.95 US / $5.95 EU vs KOLDWR's $15, IcedBallz saves you $8–9 on shipping for single orders.
- Proven product. KOLDWR is a rebrand of a sold-out brand with no track record of fulfilled orders under the new name. IcedBallz is live and processing orders.
Where KOLDWR Pro Wins
- Price on 2-unit orders. At $99 for 2 with free shipping, KOLDWR is significantly cheaper per unit ($49.50 each). If you're buying for a partner too, KOLDWR wins on price.
- Multiple sizes. S, M, L, XL sizing may fit better for men at the extremes of the size spectrum vs one-size-fits-all.
- Bryan Johnson angle. KOLDWR leans hard into the Bryan Johnson / fertility biohacking narrative, which resonates with that specific audience.
The Honest Bottom Line
KOLDWR Pro is the first real direct competitor to IcedBallz — same concept, similar materials. If you're price-sensitive and willing to wait 8–10 weeks, KOLDWR's 2-for-$99 deal is compelling. But for most sauna users, IcedBallz delivers better value today: ships now, 50–100% more cooling time, anatomically shaped for comfort, and lower single-unit shipping costs.
When you factor in that KOLDWR charges $15 shipping per single unit (making it $74 total — essentially the same as IcedBallz at $74.95–$75.95), the "cheaper" price advantage largely disappears. You're paying the same for less cooling and an 8–10 week wait.
