Written from firsthand experience with a deviated septum and checked against clinical sources. We make Ventriq Nasal Strips, so we are always upfront that a strip relieves symptoms rather than fixing the structural problem. Read our methodology or our editorial policy.
If you climb outdoors or in the gym, the best nasal strips for rock climbing are sport strips with enough spring tension to keep your nasal valve open while you are pumped, breathing hard on a crux, or trying to stay calm a few moves above your last piece of gear. A strip will not add strength to your forearms and it will not turn a hard route into an easy one, but it takes one small variable out of the equation. It keeps your nose open so you can breathe through it instead of gasping through your mouth at the exact moment your arms are screaming and your head needs to stay clear.
I started using nasal strips for sleep after a consultant otolaryngologist at a private hospital in Dublin diagnosed me with a significantly deviated septum and recommended surgery to fix it. I played rugby for over a decade and broke my nose more than once along the way, so the inside of my nose was never exactly straight to begin with. I put the surgery off to keep playing and built Ventriq as a way to breathe properly in the meantime. I am not a climber myself, but the pattern climbers describe to me is familiar. You are calm and controlled on easy ground, then a hard sequence arrives, your breathing gets shallow and fast, and if your nose cannot move enough air you end up mouth breathing at the exact moment you need to stay composed.
Why Nasal Breathing Matters in Rock Climbing
Climbing is not a steady state sport. You move through easy sections breathing normally, then a crux arrives and your effort spikes for ten or twenty seconds, then you find a rest position and try to recover before the next hard move. How you breathe during those rest positions has a direct effect on how quickly your forearms clear lactate and how quickly your heart rate settles before you commit to the next sequence.
Nasal breathing slows your breathing rate, warms and humidifies the air before it reaches your lungs, and triggers a calmer response in your nervous system than mouth breathing does. The nose also produces nitric oxide as air passes through it, and nitric oxide acts as a bronchodilator and a vasodilator, meaning nasal breathing helps open your airways and relax your blood vessels a little, which supports oxygen uptake. When fear or effort pushes you onto your mouth, you lose that calming effect right when you need it most, on an exposed move or a long reach with poor feet.
The catch is that the nose struggles to move enough air once effort or adrenaline climbs high enough, and that limit is lower for some people than others. A deviated septum reduces the cross section of one nasal passage, and combined with the nasal cycle, where the tissue inside your nose alternates which side is more congested on a roughly four hour rotation, the restricted side can feel almost fully blocked exactly when your heart rate spikes on a runout.
How Nasal Strips Help Climbers
A nasal strip works on the outside of the nose. It spans the lower cartilage and uses a spring action to lift the lateral nasal wall outward, widening the internal diameter at the nasal valve. The nasal valve is the narrowest point in your entire airway, and it is the same spot that pinches inward if you press gently on the side of your nose while breathing in hard.
For a climber with a deviated septum, the strip helps most on the side where the deviation crowds the valve area. For a climber with no structural issue, the main benefit is stopping dynamic valve collapse, where the cartilage gets pulled inward under a heavy breathing load, whether that load comes from physical effort or from the adrenaline of being run out above gear. In both cases the practical payoff shows up while you are shaking out on a jug trying to settle your breathing before the next hard section, and on long approach hikes to the crag where nasal breathing keeps your pace controlled.
I use the Ventriq Sport Nasal Strips for anything active. They are stiffer than a standard sleep strip, built to stay put through sweat, and the adhesive holds through a full session at the wall or on rock without peeling at the edges, even once chalk dust gets involved.

What to Look for in a Rock Climbing Nasal Strip
Not all nasal strips are built the same, and for climbing a few things actually matter:
- Adhesive strength: standard strips give up as soon as chalk dust and sweat mix on your skin. You need a strip made for sport, with an adhesive designed to grip through a long session.
- Spring tension: more tension means more lift and a more open airway. A soft strip made for sleep will not give you the same airflow under a heavy breathing load on a hard route.
- Fit and position: a strip that sits too high on the bony part of your nose does nothing. It has to sit across the lower cartilage where the nasal valve is, and it should sit low enough to clear sunglasses or a helmet if you wear one.
- Skin tolerance: if you climb most days and spend hours at the wall or the crag, you want a strip that does not leave your skin raw after you peel it off.
I have tried a lot of strips over the years. Most were fine for sleep but failed the moment sweat and chalk got involved. The Ventriq Sport strip holds better and keeps lifting the airway open through a long session.
Does It Actually Improve Performance?
I will be straight about this. The research on nasal strips producing measurable performance gains in trained athletes is mixed. Some studies show small improvements in perceived effort and breathing efficiency. Others show no meaningful change in aerobic measures or power output under laboratory conditions. A strip is a breathing aid, not a strength upgrade, and it will not raise your grade or grow your forearms.
What I can tell you from what climbers tell me is that the subjective difference is real. Breathing through your nose while shaking out on a rest feels calmer and less rushed than gasping through your mouth, and it is easier to hold your composure on an exposed sequence when your breathing is not ragged. Whether that turns into a sent route depends far more on technique and strength than on your nose. If you want the deeper look at the evidence, I have covered it in Do Nasal Strips Improve Athletic Performance.
Nasal Strips if You Have a Deviated Septum
If you have a deviated septum and you climb regularly, nasal strips are probably more useful for you than for the average climber. You are starting every session with your airway already restricted, so anything that gives part of that width back levels the field a little on the moves that spike your heart rate. External strips work best when the restriction sits at the nasal valve rather than deep inside the nasal cavity, which is the most common pattern after a knock to the nose. I have written more on this in Best Nasal Strips for a Deviated Septum.
If your breathing also wrecks your sleep and slows your recovery between climbing days, How to Sleep Better with a Deviated Septum covers what has worked for me overnight.
My Recommendation
For climbing, get the Ventriq Sport Nasal Strips. They were built for active use and they stay on through chalk, sweat and a full session at the wall or the crag. If your main need is breathing and recovering better overnight after a big day out, the Ventriq Sleep Nasal Strips are the right pick for bedtime, and plenty of climbers use both, sport strips for sessions and sleep strips overnight. If you also train grip and pulling strength off the wall, the same thinking applies to weightlifting, and if long approach days are part of your routine I have covered nasal strips for hiking too.

Frequently Asked Questions
Are nasal strips allowed in climbing competitions?
Yes. Nasal strips are a mechanical breathing aid with no drug action, so they are not on any prohibited list, and no climbing competition rule bans them. You will see competitors wearing them at the wall.
Can I wear a nasal strip with sunglasses or a helmet?
Yes, as long as it is positioned correctly. A strip sits across the lower cartilage of your nose, well below where sunglasses rest and well below a helmet strap, so the two do not interfere with each other.
Where exactly should I place a nasal strip?
Position it across the fleshiest part of your nose, over the lower cartilage rather than the bone. If you feel the spring tension lifting your nostrils when you breathe in, it is in the right place. Sit it too high and it does nothing.
Do nasal strips help with the pump you get in your forearms?
Not directly. A strip does not change how quickly your muscles clear lactate. What it can do is help you breathe in a calmer, more controlled way while you shake out on a rest, which makes the recovery window feel less frantic even though the underlying pump is a muscular issue.
Do I need a deviated septum for nasal strips to work?
No. Dynamic nasal valve collapse, where the side of the nose pulls inward under hard breathing or adrenaline, is common even in people with a perfectly straight septum. A strip prevents that collapse and improves airflow either way.
Will a nasal strip stay on during a long day of climbing with chalk and sweat?
A quality sport strip is designed to hold through sweat and dust for a full session. Wiping the skin clean and dry before you apply it will help it grip for the whole day, including on longer multi pitch outings.
