If you searched for Obermeyer I-Grow instructions expecting a plant grow kit walkthrough, here's the important thing to know first: the Obermeyer I-Grow is actually a children's outerwear feature, not a gardening product. If you want the exact step-by-step for using the system at the right time, see the quick release and care guidance below I-Grow instructions. It's a built-in extended wear system on kids' jackets and snow pants that lets the garment grow with the child by releasing hidden fabric tucks when needed. The setup instructions are simple and clothing-based, not horticultural. That said, this guide will walk you through exactly how the I-Grow system works, how to use it correctly at each stage, and how to care for and store the garment so you get the most seasons out of it.
Obermeyer i Grow Instructions: Setup, Care, and Troubleshooting
What the Obermeyer I-Grow system includes (and how to confirm your exact version)
The Obermeyer I-Grow Extended Wear System is built directly into select kids' outerwear pieces, most commonly insulated jackets and snow pants. There is no separate kit, box, or set of accessories. What you have is a garment with extra fabric tucked and sewn into the seams or hem, held in place by a single release thread. When your child grows and the original fit gets too snug or too short, you snip that thread to release the extra fabric, effectively gaining up to one additional size of length in the sleeves, hem, or leg.
To confirm you have an I-Grow garment, check the inside hem, cuffs, or ankle area of the jacket or pants for a small sewn fold of fabric and a visible release thread, sometimes tagged or labeled. The hang tag or care label on your specific piece should also reference the I-Grow system by name. If you bought the jacket or pants as part of Obermeyer's I-Grow collection, this feature is included by design.
- Insulated jackets with I-Grow sleeves and/or hem tucks
- Snow pants with I-Grow ankle/leg length tucks
- A single release thread per tuck point (no tools needed beyond small scissors)
- Care label or hang tag identifying the I-Grow feature
- No separate parts, hardware, or accessories included
Quick start: from unboxing to first use
When you first get the garment, fit it on your child in its default (tucked) configuration. This is the smaller, initial size. The garment is designed to fit well at purchase while still having hidden growth room built in. You do not need to release the tucks right away, and you shouldn't unless the original fit is already too short or restrictive. Think of the tuck as a locked-in upgrade you'll use when you need it, not something to activate on day one.
- Remove the garment from packaging and locate the I-Grow release thread (check cuffs, hem, and ankle seams).
- Try the jacket or pants on the child in default mode to assess the starting fit.
- Leave the release thread intact for now unless the fit is already too short.
- Register your Obermeyer purchase if prompted by the hang tag or packaging inserts.
- Store the garment properly at end of season so the tucks remain clean and intact for next year.
How and when to release the I-Grow tuck

The release step is the core 'instruction' for this system, and it's genuinely simple. When your child has grown and the sleeves look too short, the hem rides up, or the snow pants are sitting above the ankle, that's your signal. Find the release thread on the tucked seam, cut it cleanly with small scissors, and gently pull the fabric fold open. The garment will extend to its full, larger size. There's no sewing required and nothing to reattach.
One important note: the release is one-way and permanent. Once you cut the thread and release the tuck, you cannot fold it back. Make sure the child genuinely needs the extra length before snipping, because you can't undo it. If both sleeves or both pant legs have tucks, release both at the same time so the garment is symmetrical.
Where to find the release thread
- Inside the sleeve hem on jackets (look for a folded cuff seam with a contrasting or matching thread tag)
- Along the bottom hem of the jacket body if body length is also extendable
- Inside the ankle hem on snow pants
- Sometimes marked with a small icon or label reading 'I-Grow' directly on the tuck
- Check both sides independently, as each tuck has its own thread
Ongoing care routine to protect the I-Grow feature

Because the tuck is a structural part of the garment, how you wash and store the piece matters. Aggressive washing or heat can damage the tuck seam before you're ready to release it, or cause premature release if the thread weakens. Follow the care label instructions on your specific garment, but a few general rules apply across all I-Grow pieces.
- Machine wash on a gentle or delicate cycle in cold water.
- Use a mild, non-abrasive detergent, avoid bleach and fabric softeners which can break down seam threads.
- Tumble dry on low or hang dry to preserve insulation loft and seam integrity.
- Do not iron directly over the tuck area, heat can melt or weaken synthetic seam threads.
- Store folded loosely or hung, not compressed tightly in a stuff sack, which puts stress on the tuck seam over months.
Troubleshooting common I-Grow issues
The system is simple, but a few problems do come up. Here's how to handle the most common ones quickly.
| Problem | Likely Cause | Fix |
|---|---|---|
| Can't find the release thread | Thread is hidden in a folded seam or blends with fabric color | Run your finger along the inner hem to feel the fold, then look closely with a flashlight or in good light |
| Tuck released unevenly or partially | Only one side was cut, or thread broke partway through | Check the other side and release the remaining thread fully, then smooth the fabric flat |
| Garment looks asymmetrical after release | One tuck released earlier than the other | Release the remaining tuck on the opposite sleeve or leg to restore symmetry |
| Thread broke on its own (premature release) | Washing or storage stress weakened the seam thread | The extension has already activated, the garment is now at full size, use it as-is |
| Tuck area looks puckered or uneven after release | Fabric was compressed in storage | Wash gently and hang dry, the insulation and shell fabric should relax back to shape |
Safety, cleaning, and storing between seasons
At the end of ski or winter season, give the garment a proper wash before storing. Dirt, sunscreen residue, and salt from snow can degrade waterproof coatings and weaken seams over a long off-season storage. If the garment has a DWR (durable water repellent) coating, a low-heat tumble dry after washing can help reactivate it, and a purpose-made DWR spray can be applied if the shell is starting to wet out instead of beading water.
Store the jacket or pants in a breathable garment bag or a drawer, not in a vacuum-sealed bag or tightly compressed storage cube. Compression over months puts sustained stress on all seams, including the I-Grow tuck, and can cause premature release or seam damage before the child needs that extra length. Keep it somewhere dry and away from direct sunlight to protect the fabric and coatings.
Final checklist and next steps for getting the most out of I-Grow
Whether your child is about to outgrow this season's fit or you're preparing for next year, here's a quick reference to keep the system working as intended.
- Confirm the tuck location on your specific garment before you need it (sleeves, hem, ankles).
- Monitor fit at the start of each season, not mid-season when frustration peaks.
- Release both tucks on matching seams at the same time for symmetry.
- Wash the garment gently before and after each season of use.
- Reapply DWR treatment if water is no longer beading on the outer shell.
- Store in a breathable, uncompressed space away from heat and direct light.
- If the garment is already at full I-Grow size and the child has still outgrown it, check Obermeyer's current season sizing for the next size up.
The I-Grow system is one of those features that works best when you know it's there and plan around it. If you need woombie grow with me instructions, use the same approach: check the label for the system name and follow the release and care guidance for your specific garment I-Grow system. Kids grow fast, and having a jacket or snow pants that buys you an extra season without a full repurchase is genuinely useful. If you came here expecting a plant grow kit guide and this isn't what you were looking for, it's worth double-checking the brand name on your product, as other grow kit systems covered on this site (like seed-starting sets and hydroponic countertop units) can sometimes surface under similar search terms.
FAQ
How do I tell the difference between Obermeyer I-Grow and a jacket that just has removable inner liners or adjustable hems?
Look for a sewn fabric tuck plus a dedicated single release thread inside the seam or hem area (often near cuffs, inside hem, or ankle/leg). Adjustable hems usually use snaps, zippers, or elastic hardware, and removable liners are part of the lining construction rather than a permanently tucked seam held by one cut thread.
What should I do if I cannot find a release thread on my Obermeyer I-Grow garment?
First, check multiple spots along the seam where the tuck would be (cuff/hem for jackets, ankle/leg for snow pants). Then recheck the care label or hang tag for the I-Grow name. If it is not referenced there, you may have a similar-looking design without the extended wear feature, and cutting seams based on guesswork can damage the garment.
Can I release only one side (for example, just one sleeve) if one arm is longer or fits differently?
It is possible in many cases, but it can make the garment look uneven and may shift the way the tuck lay lies under the sleeve or cuff. If the jacket has tucks on both sides, a safer approach is to release both matching tucks at the same stage when they are needed so the fit stays symmetrical.
Is the release completely irreversible, even if I cut the thread accidentally or too early?
Yes. Cutting the release thread permanently frees the extra fabric, and you generally cannot refold it back to the original locked configuration. If you cut by mistake, your practical options are to use the garment in its newly extended size or, for appearance, have a seamstress add temporary closure, but that typically requires sewing.
What is the best time to wash before releasing the tucks?
You can wash at any time, but avoid high heat or harsh cycles before you want to release later. If you plan to keep the garment in its smaller (tucked) size for a while, stick to the care label and use gentler drying methods so the release thread and tuck seam do not weaken prematurely.
Can I reactivate or restore water repellency after washing, without affecting the I-Grow system?
Yes, if the care label allows it. Use low heat only, and apply DWR products specifically intended for the fabric type (shell or coated material) rather than general-purpose sprays. Be careful to not oversaturate around the tuck seam area, since excess chemical buildup can change how the seam fabric behaves.
What should I do if the garment extends but the fabric fold does not open smoothly?
Stop pulling once you feel resistance, because force can snag the seam. Gently loosen the released area by massaging the tuck while supporting the garment, and confirm you cut the correct thread segment. If it still will not extend evenly, do not keep cutting blindly, contact a professional tailor or dealer support.
How should I store the garment when it is not in use for months?
Store it dry in a breathable garment bag or a drawer with minimal compression. Avoid vacuum-sealed bags and tight storage cubes, because sustained pressure can stress seams including the tuck area. Keep it away from direct sunlight to reduce fabric and coating breakdown.
Do I need to do anything to the seams after releasing the tuck, like sewing or patching?
In normal use, no reattachment is needed because the extra fabric is designed to extend once the release thread is cut. However, if you notice loose stitching beyond the intended tuck area after release, keep using the care label guidance and have any unintended seam damage repaired promptly.
